What is the pressure limit of the recovery time?.

Recovery time RELEASE TIME, said before starting the input signal is greater than the level after the compressor started to work, when the input signal level below the starting level, the compressor to return to the straight state, through the state from the work resume .Time is needed for recovery time. .In general, if you need relatively large dynamic range, such as DISCO, suitable for faster recovery time, so that the signal fluctuation is relatively large, drum sounds clear, if the recovery time is slower, the compressor easy to produce like a "breathing space" as a .effect. .Recovery time of the method and modulation transfer start time Rather, generally from slow to fast regulation..

What is a divider "order"

What is a divider "order" does not talk about active crossover, only that usually 2.0 speakers after the class is used by the passive divider, in General, the divider is made up of three basic parameters. The first is the divider crossover points, this should not say any more. Second, is the so-called divider "road", which can be entered in the original signal into different frequency band signal, we usually speak of three second frequency, frequency, frequency divider "road". Third, the divider of the "order", also known as the "class". A passive divider, essentially several high pass and low pass filter of the complex, and the number of these filter circuit that is above the "road". But in each filter circuit, there are more granular design, in other words, in each filter, you can individually after many filtering, the number of times the filter, is the divider "order". Here, we see two circuit diagram, the above is "dual-frequency divider", the following is a "dual" second-order divider. Dual-frequency divider dual second order divider from the above figure, we can clearly see, first-order divider is the inductance and capacitance frequency of structure, while the second divider in every way are two filter, this "two filter" is the "second order" really means! "second-order effect, divider" this argument is not normative, because the "order" is not for the whole divider, but one of the "road", so strict that should be "dual, high-frequency prescalers are using second order filter," because although it is rare, but high frequency using second order filter and low frequency adoption of first order filter this design also is available. In addition to first-and second-order frequency frequency, passive divider three-, four-and six-color separation. The benefits of using high-frequency is its filter attenuation slope greater frequency look better, but also to design frequency compensation circuit (because not "separation", the more thorough and more clean divider is good divider, in theory, the frequency of two signal curves in the overlay, fully consistent with the original curve, this is the real good frequency divider), but the higher frequency of power loss, particularly phase high-impact, design is not a good sound is disarray. So not more-order of frequency, the better. As for the capacitor frequency or RC-crossover, it simply cannot be referred to as "divider"!, because it has only one high-pass filter signal, there is no "separation" where's the "reader"?! "-" no "order!" and the "road" confused? market 2.0 multimedia speaker, use a capacitor or RC-frequency of the majority, use divider, and using second-order frequency of less. If Shockwave SB-2000 using first-order divider, and the use of second-order frequency, then only the hivi T200A, M200, movers to S2000, such as the chosen few. 1900TIII (Soomal Note: many high-end speaker is a second-order crossover) Shockwave SB2000 first order frequency divider movers to R1900TIII a second order divider "high-end speaker" resistor divider PostScript: Let me what to say? of course, now the media who are aware of the situation, to little compile not to write their own do not understand technology and to each media incurs an audio expert, not reality. However, we suggest that controlled his mouth to say that they are not aware of it so difficult to Delirium? false expert, when it so pleasant feeling and thinking the same? not long ago in a famous IT website see Super perfect, the small series was considered one of the vice speaker 2.0 versamat played is balanced and auxiliary tank volume, but also very positive in evaluating! X! versamat actually became as volume module that is used to reduce the volume of the box! (actually the contrary that the versamat have absorption acoustic role, its role is equivalent to increasing the volume of the box! so placed within the Deputy Chamber versamat is actually a very unscientific approach)

Effects of classification

The so-called effects, as the name implies, to impose tone effect (the effect, impact), is not only the many musical instruments, electric guitar, choir, use it, when you hear the music, almost all have been processed. Not after processing of music (no, the effector) gives people the feeling of a fly in the ointment. Can be said that the effects in music composition, is essential. In this, the electric guitar is representative for an explanation of the effect. As the effective use of the effects of the getting started guide, hope can be made out of high-quality audio at the same time, can take this as a study on the effects in the other instruments in use, constitute the music all in the effects ideal aspects first step. Guitar if you can only play on words, is not called and qualified. Playing music, phrase, you must be able to quickly fix and playing my personality fit the tone. If the wrong tone, volume, the phrase became meaningless things, sabotages its coordination (Unity). 1. distortion effects (Distortion) in many electrical appliances, in the "Rock" of the world, are so many people are using, use the most is the distortion. In want and no distortion of the clear tone for comparison, the volume is restricted to a certain degree, to issue the distortion sound, distorted exchangers have become quite convenient. The input signal to the intentional distortion is the basic structure of the distortion. Distortion control, usually by regulation distortion, so sound changes TONE on TONE is adjusted by the LEVEL of the three devices. Distortion, even through the guitar itself, its volume adjustment or change in the distortion method. Guitar volume if it is 10, then, is the distortion, slowly swirling low volume small distortion slowly. Moreover, the volume decline at the same time, it is extremely close to the original audio. Therefore, if you use this, you can use a speaker at maximum volume location when playing the same feeling to play. For heavy rock, want to use as marshall as speaker, I would like to advise you in this distortion to into guitar volume control. 2.Over Drive overload effects largely belong to the distortion system effects, but the slight distortion sound is its charm, and the original distortion or there is a difference. There is a clear distinction between them is through the tone differences to distinguish. Distortion of timbre tend to heavy rock more rough distortion method, while Over Drive is much more delicate than the former also pleasing to the ear of many of the distortion method. In order to reproduce when using electron tube speaker sound distortion of natural and manufactured. 3.Phase phase effects because it is the mobile phase (phase), also called phade.shifter. Through the left and change relative to the original audio phase mix together, produce a sense of depth of cyclotron to via electrical and produces a rotary speaker effects created by the effects. (Also called swing effect) 4.Flanger unpredictable effects like chorus, Flanger and give a little more than true Vocality audio delay is, pass into the pitch up and down the scratchy feeling shaken, the tone of an effect. The so-called Flanger is gently press the tape recorder, which deliberately produce Flange of Rotary effect of sound and original audio mixing effect of skills in the name. 5.Equalizer (balancer) Equalizer effects just as its name, is the balance of effects, and mounted on the amplifier on tone.control (tone control is the same function can control more subtle sound quality. Because playing places temperature, humidity, guitar tone will be different. At this point, you should use balancer to adjust the sound, making it the same as usual. It can be said is a studio recording is absolutely necessary. A) Graphic.equallzer (graphic equalizer) by increasing, slashing distribution in several frequency bands in the regulator, the subtle sound quality adjustment possible. B) Parametric.Equalizer (parameter balancer) graphics balancer, the number of frequency band is pre-set, but parameter balancer, you make it variable, and because the center frequency ranges can change, the more precise control is possible. 6.Digital.Reverb (digital reverberation) used to make sound, although guitar amplifier with subsidiary Reverb (reverberation) are the same, but it is not used for Analogue Reverb (analog reverberator) that produce physical vibration, but to make the code entered into digital information quickly. Through the program control results produce sound. 7.Exciter (incentive effects) due to the structure, can be divided into multiple, but the basic effect is: make code extension, manifest, that is to outline the capacity will be gone branch becomes suddenly sounds. 8.Pitch.Shifter (tone changes) as the text indicated, is the effect of changing the pitch. The variety of mixed up between Cheng, to create a lively and sound, plus pitch change of tone, you can get the very nature of chorus (choir). 9.Noise gate (noise reduction) have a certain level of the signal to cut off the effects of the function. In other words: the playing of sound began to weaken, weak to certain volume below come into play so that unnecessary sounds not issued. To which location you can cut the volume. By threshold (threshold). Decision of eliminating the Release time. 10.Limiter (limiter) have limits above a certain volume of peak (peak) of effects. In other words: the Elimination of excess, volume preventsExcessive input of distortion caused by, without changing the tone of the get very pure sound quality continuing effect. 11.Chorus (Chorus effects) Chorus is to extend the left a little to make the tone pitch slightly up and down, then mixed with the original audio, resulting in noise and natural extension. Is the effect of the tremolo system in use at most. No matter how species: clear, distortion. No matter what sound portfolio is its very convenient effects. In addition, efficient use of stereo.out (stereo). We can produce quite vast code. 12.Delay (delay effects) delay unit such as text, by extending the original audio to enable sound effects for extended. Delay time to use msec to indicate, in addition to the Delay time (DTIME), adjust tone repeatedly several feed.back (F.RACK), adjust the level of effect.lever (E.LEVEL). a total of three knobs to control all of the delay. In addition there is the tone duration swich.off repeatedly sustained (hold). 13.Compression (compression) produce close to the original audio, there is no distortion of the effects of sustained results. Compression on larger tone down its volume, tone on smaller, increasing its volume, the volume to sustain averaging. In addition, no distortion, refers to make up the play sound can change form and true Vocality charm different unique Compression.sound. 14.Multiple.Effects (combination of effects) is not to undermine the effects of personality, but put it together in a single, called Multiple.Effects. To date, Reverb, Delay, Pitch Chourus Flanging, Shifter and other effects of effect can be produced, and recently also the guitar player who used in Canada to have the low-Distortion, and other functions and features high quality results. As a small effects, their light is not enough, but for the amateur, become an indispensable things around it is a fact. 15. "Wah Wah (WOW pedals) maintain a specific frequency in peak, through the pedal effects of its movement. Tone knob is pedal, specific range more than true Vocality is conspicuously emphasized, other range sounds like weak, this is its characteristics. In General, step forward, the tone is sharp, returns to the tone becomes smooth. Usually there are side movement while playing against sexual play method, select sound, a little movement pedal play method. Whether romantic melody, or rock and roll, is quite a wide range of effects.

Digital signal processor performance and evaluation criteria

Digital signal processor (DSP) performance can be divided into three grades: low-cost, low-performance DSPs, low energy consumption in the DSPs and diversification of high-end DSPs. Low-cost performance of low end DSPs is the industry's most widely used processor. In this context are: ADSP-21xx, TMS320C2xx, DSP560xx series, their running speed is 20 ~ 50MIPS, and in the maintenance of appropriate energy consumption and storage capacity at the same time, provide high-quality DSP performance. Affordable DSP processor, by increasing the clock frequency, combined with more complex hardware to improve performance, formed the DSPs's in products such as DSP16xx, TMS320C54x series, their operating speed to 100 ~ 150MIPS, are commonly used in wireless telecommunications equipment and high speed modem, requires relatively high processing speeds and lower power consumption. High-end DSPs since being super high-speed processing needs, its structure and really start to diversification, the structure of the next section. High-end DSPs's clock speed reached above, the processing speed 150MHz as 1000MIPS above, such as TI's TMS320C6X series, ADI SHARC for Tiger. Evaluation of performance indicators for many, the most common is the speed, power and memory capacity indicators is also very important, especially in the embedded system applications. In view of the increasing number of DSPs, system designers to be elected in a given application equipment to be able to provide the best performance of the processors become more difficult. In the past, the DSP system designers rely on MIPS or a similar measure, to probably understand different chip provides relative performance. Unfortunately, with the processor technology diversification, such as MIPS increasingly inaccurate traditional metrics because MIPS and not the actual measured performance. Because the DSP application is one of the characteristics of most of the processing work is concentrated in a part of your (core), and therefore can be used with signal processing related benchmarks to test assessment DSP processors. BDTI company has completed the set of core standards, and register a new mixed speed measurement: BDTI score.

To the Beijing Olympics opening ceremony as accounts with large stage sound covers

BOCOG despite the commitment of not more than 8 million (the total cost of the Athens opening) this figure, but in some performance industry, the current Olympic Games opening ceremony cost also is astronomical, absolute need of millions. Have participated in the same song, Daxing, Taizhou, station planning and organization over the famous singers such as Yu Quan concert haoyi Boya, Guo xuefeng thoughtfully said: "any of the cost elements of the charges I'm afraid all to millions. "Guo's basis is very simple, he a friend of mine is the curse of the" global premiere of producer, the premiere of total cost is 10 million RMB. Despite all this the opening ceremony of presumably will be millions, but no one can give an idea of the expected range. The same song "pay with Kyrgyzstan considers opening ceremony cost everyone there is no way to give a specific estimate, because in the industry, even for the same equipment, different operations team to offer is different, moreover, did not see the opening ceremony of the stage. Guo xuefeng holds the same view, that it is difficult to specifically calculated the cost of opening, because even a similar stage effect, if the application of stage technology, the cost differences are also separated by thousands of miles. But in any case, the calculation of the cost of major expenditures in the opening rate is still traceable. The opening of the first accounts: stage theatre art design including the charactor, make-up, costume, scenery, props, lighting, acoustics, sound and lighting accounts for a large scale. Guo xuefeng said SBS from being leaked the opening scenes, the current Olympic Games opening ceremony stage lights may need a thousand million RMB. Because the lighting is very high-quality equipment. Olympic sound Adviser Wei Zeng to teacher explained that the stadium sound reinforcement system is inherent in the use of game sound reinforcement, mainly to meet the General command of the race. But the opening ceremony is actually a form of performance, it is not appropriate to use such a distributed way sound reinforcement. Therefore, in General, the stadium sound reinforcement in the opening ceremony (including concert) are used in addition to rent. But no matter what brand of device selection, section pure import value of the top equipment is expensive. It is the Olympics the dress rehearsal of the audience said, national stadium, for game design position lamp lights of 663, angle, but it was already covered with membrane. Related sources, opening ceremony, Beijing National Stadium original lamps was "retired". General Director Zhang Yimou's "own" lighting and sound equipment to enter the National Stadium. The opening ceremony of the second accounts: personnel costs: production team, staff and the actors, the external guidance experts who know the current Olympic Games opening ceremony of luxury production team up to 300 people, including cost much frightening of external expert guidance. Guo xuefeng considers opening audio lighting experts should be internationally leading roles, and these costs is difficult to predict, but the General performance activities to engage external experts to China for a visit at least ten million. Therefore, although announced the opening of personal remuneration would be better than in many countries, staff are low, Guo xuefeng still believe that the production team of millions of dollars of cost probably need at least, because I am afraid that only external experts will spend this figure. This opening will have 1 million staff and actor has no secret, put aside their wages do not speak, eat to live alone, this is a great cost. Just look at the catering of flowers, even per person per day in only 10 Yuan, the entire team needs $ 1 million every day. Then take into account the cost of living, it is expected that this section will have a few million RMB. The opening ceremony of the third accounts: special effects: stage stunts and Fireworks stage stunts is very difficult to estimate, because the current Olympic games use a lot of new technology, and some special effects lights in other major activities are not using it. Should be the West's system, you may also use the Harvey lights and other advanced lighting equipment, this part of the basic no way to quote in the country. Although the Beijing Organizing Committee for the opening, closing ceremony of the Deputy Minister, on, closing operations center director Wang Ning said shell of less than the entire opening costs 1%, but Guo xuefeng continues to believe that the cost of fireworks. From BOCOG on fireworks and environmental protection requirements, the cost of a second shell may need tens of thousands or even tens of Yuan. July 23, the Beijing Organizing Committee for the opening ceremony of the Beijing Olympic Games has released the firework display. Under the programme, the August 8 opening day will be setting off fireworks 3.5 million, total duration 20 minutes.

World University Winter Games opening ceremony with over 70 10 million audio only

Harbin World University Winter Games opening ceremony held on 18 May. It is learnt that the stage lights splendid sound shock dresses up wumei gorgeous. These are the stage LED screens, plus venue walls are also installed on the LED screen, you can imagine, the opening ceremony of the world to bring viewers, will be a solid, full of beautiful experience. Heavy use of LED most invasive province World University Winter Games opening ceremony at Harbin's stage, it can be said is a Director of the Group crafted — stage is divided into four layers, namely the ice arena, flat stage, the stage and in the high-altitude air stage. And, the stage is composed by the LED screen, plus venue walls are also installed on the LED screen, you can imagine, the opening ceremony of the world to bring viewers, will be a solid, full of beautiful experience. This reporter has learned that the opening of the LED screen up to 3000 square meters, so large-scale use of LED screen, in the province for the first time. Don't underestimate the LED screen, at the opening of the rehearsal process, they embody the beauty of feeling already let reporters ecstatic — — LED screen sometimes play would represent an unique construction, sometimes play would embody the culture of the blue, and it will also be able to cope with the actor's performance transform content and better service for performance. Although only the dress rehearsal, LED yet fully play its power is enough to shock, formal performance results, really make people look forward to. Opening ceremony held executive director Wang told reporters: "stage design style, is to strive to embody the world on the theme of youth. The opening ceremony with a lot of LED screen, use them, what do you want to render the scenery can be realized, no longer subject to the restrictions for props. In addition, the LED screen can also be full realization of the performance and content of the interaction, not only to give viewers a better interpretation of the meaning you want to show, but will also let the program. "Light strip effect brings Visual Feast by LED screens erected stage allowing players to better perform their own programs, if combined with the perfect mix of light and atmosphere of contrast, in front of an audience of it will be a splendid visual feast. So, you want to create a perfect performance, light is an indispensable part. Since the opening ceremony at the international exhibition and sports center stadium, so the specific site conditions decided to perform a square form compatible and theatrical features, this light made very high requirements. "Different performances in the form of light have different requirements, so the Director Group ultimately took out a comprehensive programme with a whole new light. In order to contrast scene atmosphere, the atmosphere light and movement, and other light approach we used, and strive to achieve the effect of a flowery, "Wang said. In order to be able to create a better visual effects, the opening performance used to stage lighting available are upscale, opening stage Director, Harbin Golden songs Optical Engineering Co., Ltd. General Manager Lu Jia Qi told reporters that: "the opening of the equipment used is a high-grade, in line with international standards. Computer lamp with over 200 computer and all imported from Italy. In addition, the high lifting point lights have 200, so much use of lighting, size and quantity are the best in the province. "We may not know, all of the opening ceremony of the lighting design and installation are professionals, for example lifting point of design, is a specialized according to the venue features design Institute. According to Lu Jia Qi's words, it is the "professional design, construction, professional team of specialists on duty". Audio international quality create according to Wang Qi hearing shock, the current World University Winter Games opening ceremony of sound equipment is used by the Beijing Olympic Games opening ceremony, the sound quality is excellent, high quality, with large performance comparable to the rest of the world. Just listen to the device model, make, as the audio aspect of non-professional journalist puzzled, but heard the price of these devices is sufficient to let reporters Raspberry. A speaker 10 million Yuan, in the opening ceremony, the speaker took a total of more than 70; performances are using digital master mixer is the world's top, one has to millions more ... See, the price is not low, World University Winter Games opening ceremony audio hardware facilities, absolute is world-class. In addition, the sound design is by our company, it is a world class production companies.

After the visit to the market, we set-top box karaoke equipment and computer karaoke equipment also have some understanding of, and K family of friends and share it, but also to purchase karaoke song VOD equipment friends some reference. There are many friends in the purchase of household karaoke song VOD equipment hesitant, I do not know what to buy a set-top box-karaoke machine, or the buy computer karaoke machine. We all know, the song of this machine has been in the computer of the 1990s blockbuster, mainly used in the song and dance halls, nightclubs, entertainment, home of the DVD player and karaoke discs. But in a DVD player, you need to keep the purchase Karaoke CD to update the storehouse, for home users, it is not very effective. Set-top box and computer equipment as a karaoke song, the competitive advantage which the competing, then a more suitable home? in visits to the market, we set-top box karaoke equipment and computer karaoke equipment also have some understanding of, and K family of friends and share it, but also to purchase karaoke song VOD equipment friends some reference. 1990s blockbuster computer karaoke machine hard drive is small, the songs are mostly computer Karaoke system features a large, each song average size is 10 MB or so, such as a hard drive can hold 120G thousand songs. In the PC VOD system, DVD version of the computer screen and sound quality VOD system are better, other versions of PC VOD system sound images is not afraid to flattered. STB-VOD system in the storehouse to blend the storehouse, depending on the format used is functional distinctions; General dvd, vcd and ksc format, most of the original human singing, screens and DVD comparable; sound directly from releasing pressure from dvd output to power amplifier, fidelity is very good. Built-in 1000G hard-STB, generally the first number is 18000 songs. While the set-top box capacity not as computer Karaoke system capacity, but the sound quality is very good picture. Today, the rise of the STB karaoke machine extensibility is better is the DVD version of the PC VOD system of a large advantage, some versions of PC VOD system software because specifically for standalone, extended more difficult. Set-top box software and hardware integration itself is relatively high, would like to other version upgrade does not have a computer version of a convenient and flexible.

Feedback suppressor how to debug?

Feedback suppressor eliminates feedback whistling phenomenon, while maintaining a sufficient volume and good-quality methods and procedures. In conferences, performances, lectures, reports and many other occasions, good sound reinforcement systems are indispensable. 10. repeat 9 until all the LEDs of filter, and one in Flash, which indicates all fixed dynamic filter has been set up in the adjustment process Note: 1. the adjustment is complete, if you increase the system volume, the feedback will not be suppressed 2. clipping level of control to fit, too high may signal clipping or distortion, so the end of the letter Mania than low-or produce the "hissing" sound.

The basic principle of divider

Current speakers are primarily dynamic speakers of the world, which in essence is an electro-acoustic energy conversion device that transfers sent signals converted to sound output. It is well known that the human ear can hear the sound frequency range are generally called audible 20Hz-20KHz, acoustic (audible sound) or audio (audio), single horn to cover such a wide range of frequency bands, and a good balance between high and low frequency extension of both ends, achieve low distortion and high transient, high-power load capacity is not possible (in the current technical condition of release is not the speakers to the future it may be possible). Single speaker is very difficult to override the audible sound (audible sound) on this point, the new Hai has a very vivid descriptions: "as the road police, if the pipe is too wide and would eventually and the tube period is much easier", the speakers also is the reason that the solution to this problem is most simple and effective way to replay the band. So there are a work in a different frequency range of speakers, subwoofer unit cell, baritone, bass, treble unit, ultra-treble unit and so on, this kind of "base" of the targeted design, causes the performance of each unit are relatively stable, in order to work in a State of low distortion. Since the majority of speakers now using multiple cell division band replay of design patterns, so you must have a device capable of full-band music signals as needed into different frequency band signal, thereby entered into the corresponding speaker session, this device is the divider: similar to a complex path scheduling, is it the sound signal "classified" arrangements in their respective jobs. Divider will sound signal "classified" arrangements in their respective job if the band signal with a "shunt" direct input to the high, mid, bass unit, the unit replay frequency signal outside the part of the "extra signal" on normal in-band signaling restore adverse effect (the term is referred to as "modulation distortion"), the sound will be messy haze, kept, and this is just a lighter, more serious consequence is the power of bass signal cuanru treble, Alto session, beyond the power of this unit is hosted, thereby directly damage the unit.

Feedback suppressor of Whistler active suppression and passive restraint?

In sound reinforcement system feedback of excessive performance is Whistler, is the microphone audio gain elevation limit performance, is the result of peak overlay. In response to this phenomenon, it proposed a variety of enhanced microphone audio gain methods such as reasonable sound field layout, additional sound absorbing materials, changing sound reflection characteristics and so on physical means to avoid this kind of phenomenon from occurring, meet the functional needs of sound reinforcement of sound pressure. Through electroacoustic device compensation means to achieve improved microphone audio gain goal is also often used. Electroacoustic device compensation means also divided into active mode and passive mode. Shift is a typical active suppression tool, how it works is the audio signal through the shift change in original frequency (entered in Hz signal is 1K, out of the signal is 995Hz) and thus destroyed the peak overlay, so that the frequency response curve tends to flat sound reinforcement system get higher average audio gain microphone margin space to ensure that the initiative of the whistle. Equalizer for feedback control first is found high frequency response curve, through the bumps on the point of control is to be balanced frequency response curve, making sound reinforcement system for maximum audio gain space (-6db). Feedback suppressor works is an automatic equalizer. So said the equalizer and feedback suppressor for live sound reinforcement environment belong to passive feedback inhibition. L audio microphone gain enhancement processor built two feedback inhibition, a pressure point (parametric equalization), second shift. Is ascending tone microphone gain enhancement processor in KTV, conferences, and other environments can be used by very positive recognition, there are two reasons. 1. in the current environment for sound reinforcement feedback suppressor in the l sound microphone gain enhancement processor is the most complete, additional control measures to not mention. It has proactively inhibits (shift) and passive restraint (parametric equalization) means. When the access is most of the environment without debugging you can easily reach the singing, speech, the purpose of the prevention of Whistler. The system's audio gain new skills, the l sound microphone gain upgrade the processor to raise 3-8db. While traditional feedback suppressor can only raise 2-6db and complex debugging. Normal singing of tone: microphone gain enhancement processor almost no aural distortion. General feedback suppressor in automatic mode pressure point range constant-9db will cause great aural distortion. For reasons of speed, a lot of feedback suppressor produces sound lag phenomena. II. is the interface issues, regular feedback suppressor only line interface, many card package amplifier does not have the phone line access point. To give feedback suppression processing start, which caused a general feedback suppressor is not available in this type of environment.

The role of the audio and video matrix

Modern multimedia conference room, in order to meet the needs of different shows occasions, usually with a variety of different audio and video signal source and display terminals, although these audio and video signal source and display terminals or with composite video (Composite-Video), super video (S-Video), component video (Component-Video) or digital video (DVI, SDI) interface, but now in multimedia videoconferencing are commonly used or composite video matrix, the main reason in the following areas: · Composite video with good stability, compatibility and interoperability, transmission bandwidth small distances. But the chromaticity and luminance shared 4.2MHz (NTSC) or 5.0 ~ 5.5MHz (PAL) of a frequency bandwidth, each with relatively large crosstalk, equipment and transport requirements for standard cables, signal source, embedded cable · investment low. Super Video (S-Video) while reducing the luminance loss, brightness/color crosstalk in clear advantages over composite video, but for the present common LCD projectors, DLP projector does not reach the very obvious difference and embedded cable investment is twice as composite video, so the project is not universally by long distance transmission. · Component video signal format level has been significantly higher than composite video and super video, but for now most of the rooms is for computer display (VGA or RGBHV signal formats) services, equipment and transmission cables require a high level (depending on the intended design standards and investment budget), embedded cable · investment is high. Similar R-Y, Y, Y, B-Y, Cr, Cb component video signals are now mainly used in radio, film and television industry, and will gradually to SDI or HD-SDI transition of digital signal format, because the signal source and capital budget constraints, the Conference room use. DVI signal due to the effective transmission distance (5 meters), there is no widespread use. The service that IMIS habits on audio and video matrix no special indication that the default is the composite video format. To the composite video format output of the main equipment: camera, physical stand, cable TV modem, remote video conferencing, video tape recorder, DVD player, audio and video matrix system in the video source and display or multiplexing Terminal, will among different audio/video signal source according to user's preference for centralized control. In accordance with the input and output channel, common video matrix generally have 8 × 8 × 2, 4, 8 x 8, 16 × 16 × 4, 8, 16 × 16, 32 × 32 × 8, 16, 32 × 32, 64 × 64 × 16, 32, 64 × 64, 128 × 128, etc. General understanding that multiply the preceding figures represent the number of input channel, take the number behind the figures represent the number of output channels. Whether matrix input the number of output channels, their control methods are more or less the same: the front panel pushbutton control, isolation keyboard control, third-party control (RS-232/422/485, etc.), and can achieve the following functions: 1) can use needs in different display Terminal at the same time show the same or a different video source content 2) you can set the camera, DVD player, VCR, cable TV, video conferencing, and other various video signal for convenient handling and call 3) administrator can monitor any one channel video signal, but does not affect other terminal display content and effect 4) administrators can on any video signal recording, but does not affect other terminal display of content and results 5) administrators can designate any one channel video signal sent to the meeting of the terminal or other tracks, but does not affect other port displays the content and effect, like the matrix with BGBHV design a basic principle of video matrix is based on the signal source and display the number of Terminal number to determine the rank of a matrix, the matrix of difference (the number of channels) in price reflects the very obvious, in certain cases, the budget, so select a matrix of channels will become more sensitive, for future expansion is also a challenge. In addition, the following describes some problems as equipment selection factors to be considered.

What is pulse divider?

Figure 1 is a D-type flip-flops of ÷ 2 crossover circuit. Pulse divider has a wide working frequency, low frequency-in fact there is no limit, limit frequency main high-end decided to use the device, but also has something to do with the circuit. 1 MHz to the following may use metal-oxide-semiconductor (MOS) integrated circuit, 1 ~ 30 MHz may use the Transistor-transistor logic (TTL) circuit, 30 ~ 60 MHz is the use of high-speed TTL circuits, 60 ~ 300 MHz should adopt emitter coupled logic (ECL) circuit. The N-class ÷ 2 divider in a series, may constitute ÷ 2N non-synchronous frequency divider. This level push level frequency chain have save device and limit the advantages of working frequency is high, but has the disadvantage of delayed accumulation, when the series N is large, the last stage rollover moments and first level compared with great delay, sequential circuits is not allowed. In addition, the crossover frequency is limited to 2N also inflexible. Figure 1 D-type flip-flops of ÷ 2 crossover circuit adopts stage feedback can implement any number of frequency division, as in Figure 2. Diagram of three triggers the same pulse sequences driven, when in need to Flip-Flip, belong to synchronize with a 600 MHz prescalers. It does not delay the accumulation of problems, and non-synchronous divider compared to obtain the same number of fractional frequency shall be more devices, and operating frequency is low. In addition there is also a pulse divider, their number can be used by external frequency signal reset, called program divider. This crossover circuit has been widely used in frequency synthesizer.

How the bidding and procurement activities "cost control"

Government procurement activity's primary purpose is to save procurement costs, due to operational problems, we inadvertently, elevation of the entire procurement activities costs, savings and spend is "upside down" phenomenon, looked very uneconomical, concern, study and control of tendering and procurement activities of costs is very important. Purchase cost of control include tender operation cost, actual cost, acceptance and use cost three key links. A, tender operation cost control (up-front cost control) (a) reduce feibiao occurrence probability. Firstly, enhanced purchasing work planned, and generally not free to cancel the purchase. Purchasing units in insurance purchasing transaction, be sure to prioritize, plan carefully to ensure that the entire organization, and procurement work carried out in an orderly manner to avoid work-order and result in cancellation of the procurement tasks. Secondly, the procurement budget fight foot to avoid unreasonable result feibiao budget, so that procurement budgets remain sufficient tension, it is necessary to achieve low-cost procurement, but also to enable the successful vendor profitable, making procurement budgets both "stiff" and "flexible" quality. Once again, in settings where feibiao and invalid tender as to the statutory conditions prevail, reducing human conventions, tender documents on important matters, particularly where the invalid tender feibiao and should be marked in bold, for potential suppliers to bid to "friendship reminder", as a novice vendors provide business counselling and advice, there is not a valid tender feibiao scenarios and scenarios, you should be too cautious. (2) on the same or similar project with subcontracting tender. Government procurement plan arrangements to tend to focus on, according to the seasonal variations or work needs to be some commonality of purchasing items such as computers, air conditioners, and other arrangements in the relative concentration of time period to purchase, this will be daily sporadic purchases into amounts larger procurement project, centralized procurement by Government to achieve its fragmented procurement of scale cannot be achieved. On the one hand, you can purchase items implement vertical merge, on different procurement projects, such as product category, character, function, etc. are basically the same or similar, should be combined to put together complete, such as printers, fax machines, and so on, can be combined into "Office automation products" to purchase, this will expand procurement scale, improve the efficiency of group purchasing. On the other hand you can purchase items implement horizontal merger, in centralized purchasing of substantive action, breaking units, sectors and even geographical limitations, the implementation of similar projects across units, cross-industry, cross-border merger, to maximize the size of centralized purchasing. (3) improved operational means, promoting e-procurement. Save on Office supplies and venue rental charges, compress the running cost of government procurement. Building electronic government procurement is compression stocking costs, procurement transaction platform to quickly realize the "electronic" localities to actively establish government procurement Web site as "electronic transactions", from Protocol service platform, targeted procurement, accumulated experience, and gradually extended to the entire field of government procurement, the procurement of human needs in the procurement of goods, works or services over the network to the same financial sector submitted directly to the procurement plan, the financial sector through the network for approval, and after the approval of the procurement plan is transferred to the central purchasing bodies or procurement. Tendering and procurement agencies should adopt computer making universal document format of procurement documents, to the vendor at the same time provide paper and e-procurement documents, facilitate vendor making the tender documents, on the distance of the supplier should, through e-mail to provide procurement documents, some regions in promoting free tender documents, the vendor can from government procurement websites free download purchase documents. Evaluation work implementing paperless, places where conditions are to be high standards and construction bid, bid evaluation places to purchase the necessary computer equipment. (4) to promote regional linkage-based supplier procurement agreement. Regional interaction is in the field of government procurement and a new initiative, and the Protocol service is started on the Government procurement area linkage "golden key", the success of regional interaction patterns and enriched the agreement to promote an agreement the supplier supplies. Agreement the supplier era, the city and County Government procurement not stereotype entangled in tube separation or dogma stratigraphic establishment, from a broad perspective on issues, we must firmly grasp the fundamental principles of public procurement and basic objective work. Agreement, the supplier must be decentralized procurement, but large centralized, regional linkage may attract a higher level of the supplier, to a greater extent to achieve lower prices, more efficient, service, better target, in the start area on the linkage of the agreement, the supplier will have more of their abilities, their produce is more visible, so it is proven. Second, the actual purchase cost control (ongoing cost control) (1) the agency cost control 1, belongs to the Government's centralized procurement project should delegate the administration of centralized purchasing agencies, most of them are free services jicai, tender fees, no commissions, vendors will be happy to come to the Agency's project jicai, spending less. 2, non-government procurement projects, including the departments centralized procurement project, as far as possible by purchasing their own actions, such as temporary capacity is not enough to be the principal-agent, you should first select jicai bodies, and then select community intermediary agents, reducing agents service charge costs. (B) the price cost control 1, encourage price reasonable use three assessment methods, of minimum bid evaluation method and cost-effective method of use. In deciding what evaluation methods, according to the specific requirements of the procurement projects and features to choose the most relevant, most advantageous bid of standardized operation, in order to improve the relevance of evaluation method and the applicability to firmly. For standard custom merchandise and of universal service, adhere to the minimum bid evaluation method is used, the minimum bid evaluation method of use, do to prices for main factors determine the winning vendor, that is, all meet the substantive requirements of bidding documents, pursuant to the uniform assessment of the minimum quotation price elements to raise the minimum bid bidders as successful suppliers. Using the grading method, to reasonable setting price points the weights to determine the proportion of price points, not the pursuit of marginalization, which does not artificially set statutory minimum proportion to really reflect price factors, the importance of government procurement. Determine the "benchmark price", uniform use of low-priority process, satisfy the requirements of the tender documents and tender with the lowest priceThe tender offer price for bid basis, its price is divided into full marks, other bidders to price bid by the consolidated in accordance with the benchmark price-based equivalent price score weighting. 2, the introduction of the brand competitive brand competition generated by the huge funds to save space by purchasing a single brand to achieve, and it is inconceivable that traditionally single brand competition inevitable belts have a price protection and supply control color, procurement prices high, conspiracy tender subject to accompany marked quite surrounding. Brand competition then let including manufacturers, suppliers are tensed neural brand competition is not only the requirements of the law on government procurement, in line with the basic principles of market economy, is conducive to promoting free competition, fair competition, is also more conducive to procurement people save money, high quality and low price is no longer a tantalizing. In government procurement for the project will set the configuration for quality service and the introduction of indefinite brand, genuine brand competition, will be dealt a severe blow escort sung with standard behavior, you can really solve the problem of high prices, so that procurement people really enjoy to government procurement from low price good things. On the same brand of the same type of product only allows one vendor quote to chronological or take random lots to determine the supplier of the newspaper brand and model to because of the similar product replacement rates, purchase one choice, typically a procurement activities, purchase at least five brands should be positioned. 3. control of capital interest cost in strict accordance with the winning vendor bid to sign the contract, shall not be additional costs, prevent vendor to seek after considering the additional bid. For payment issues prevailing in instalments in spite of the procurement process in the contract, but in occupies the initiative must longer hire-drag, successful provider of capital interest burden and the greater the opportunity costs, these costs will be passed on to the procurement, leading to the purchase price is high, therefore, the payment of the total period should not be too long, and the first pay scale generally should not be less than 70% of the whole paragraph. For performance bond issues, to the legal rate setting, within not more than 2% of the procurement budget. (3) service cost control procurement practice shows that the purchase of unjustified service requirements or cannot be cashed, or influence the purchase of product quality, person should be based on the principle of equal treatment to participate in the procurement activities of the supplier, the scientific and rational set service requirements, and not through a free request to deter or restrictions on the vendor's free competition, this counterproductive for procurement goals, it is difficult to achieve savings in expenditure in the first place, on the contrary, it increases the cost of procurement. To column-free services and times, reference manufacturer warranty regulations requiring suppliers to tender documentation for specific instructions. To the life of the product, will occur in non-free services included in the purchase cost, require suppliers to quote for later reference implementation to reduce uncertainty. III. acceptance and use of cost control (late cost control) (a) in the procurement requirements to force pushing energy-saving products and the formation of the mandatory specification as soon as possible. All levels of Government Procurement Management Department to promote energy-saving products by supervision of procurement, implementation of the public procurement of energy-saving products, implementation advice to strengthen propaganda, efforts in the Government procurement clients in a broad consensus to promote energy-saving products work on government procurement, local government procurement authorities should consciously safeguard State decrees, timely feedback to the higher authorities in the area of energy-saving product purchasing process, the experience, to guide government procurement agencies specification to do energy-saving product purchasing and effectively safeguard the principles of publicity, fairness and impartiality. (Ii) acceptance should be done by purchasing themselves organizations acceptance, technology complex large-scale special projects can delegate fees low national accreditation of inspection bodies. For technical complex equipment, procurement shall require suppliers to provide relevant training and technical guidance, the use of procurement staff to master operations essentials, in strict accordance with the operating instructions for use, maintenance and care, reduce maintenance costs. True because the product quality problems and vendor installation issues (exclude force majeure factors) causing personal injury and property damage accident compensation, in the tender file description from the successful suppliers.
