C-MARK networked audio platform, Guangzhou Huangpu Theater Systems Engineering Analysis.

Guangzhou Huangpu Theatre - K series of digital audio networking platform for speakers and network systems engineering analysis of recent years, with the development of digital audio systems, people have become increasingly demanding audio systems. .Signal transmission, digital transmission needs; in the audio system processing section, you need to try to deal with bigger space. .As a PA system, the hardware level after a lot of people have not limited the use of powered speakers. .Control of powered speakers because the position itself and far apart, so, people need a desire to circumstances in a remote, capable of active speakers and the working status of the system hardware and techniques are fully and effectively. .So, C-MARK networked audio systems, has been completely solved the problem. .C-MARK brand platform digital network audio system, CobraNet technology is the digital audio system. .Where K series network digital hardware high-tech speaker is one of its five tracks are completed by a transfer audio, monitor and debug signals. .This article refers to the Guangzhou Huangpu theater projects, application of this system make a brief introduction. .Systems Engineering: blazing as fire in July, in the beautiful coast of the Pearl River - Flower City of Guangzhou, I am honored to participate in the PA system works in this installation. .The network audio system with a series of works made of K, due to the harsh conditions of the installation site, the indoor temperature reached 40 degrees, no cooling measures in the control room, so the sound system is facing a very severe test. .Denon cd audio broadcasting system has put local and sony md player, shure wireless microphone system is mainly used, the mixer of choice is c-mark cb2846 analog mixer. .Transmission system in a network transmission of audio hardware platform drc0808a, this is a 8 x 8 signal interface port, processing center uses network audio system drb-1 processing platform, the platform must deal with the signal input and output port .use. .The device itself without the analog input and output ports, signal processing in the system as a scene memory and other functions. .After the K-level system is used in the network speaker series, from the stage listening to the main sound reinforcement K12 K15, K18, and extended low frequency woofer. .In previous works, the most delays, the most tedious production of the signal cable. .However, the author used in this project in less than 3 hours to finish all the systems jumper, which is totally dominant network audio system. .In the conventional analog systems, equalization, etc. all have to make connections around, and now only need to do in the software system of virtual completion of the module connected to the connection application, the only source to do is two or three units, there .wireless systems is the signal cable, the other is five lines. .To make a RJ45 head only 1 minute, and do a XLR cable to the welding head is estimated from the cut may need 5-6 minutes, maybe you will feel movement a little slow, but the construction point of each speaker requires only a network cable laying .and a power cable. .Of course, can also lay a backup five lines, in this project, to be safe, we also laid a path for backup analog signal line, when the digital audio platform hardware failure again when enabled. .Obviously, this is under the conditions of insufficient funds, a good backup program. .Connect the power supply system hardware, the next step is to debug. .In the RS1200's software platform, the MAC code to each speaker (speaker hardware in the system ID) to add up, activate the hardware, ease of application, then the original digital system will find the preliminary work, also need to spend a lot of time. .Connection is normal in every hardware system, all the work to be fully completed in the software. .If you want to add the speaker icon on both the balance column in the processing module is called, if in some speakers with Compression, can call a number in the module column pressure limit processing module, do the sound system, trimmed ., expressive speaker pretty good. .Overall co-ordination, will feel part of the speakers need to add delay treatment, then calls the appropriate column in the module delay time delay module. .After two days of listening to a sense of agonizing trial, the system automatically trimming, performance of the hardware state is very stable. .Although some more complicated operation, very troublesome, but they are preliminary system design work to be done. .After doing the preliminary work will be recorded in the processing platform debugging a good scene. .Specific operation is very convenient and fast, only need to deal with the platform to operate with three buttons. .Three keys are: procedures on the recognition software programs: K series speaker monitoring software debugging software is based on the RS1200 platform, software platform in the RS1200 to add the K series of hardware. .Activated, double-click the speaker module monitors the debug window will appear. .Figure A, you can keep abreast of the remote speakers are in working condition, but also can monitor information such as current. Voltage, temperature, output volume, output gain, but also can set the warning signal point, the remote switch machine control. .Figure I Figure II: The engineering system connection diagram Figure III: The engineering software platform signal routing diagram Guangzhou Huangpu, Guangzhou Huangpu theater picture theater picture theaters picture Guangzhou Huangpu Huangpu, Guangzhou, Guangzhou Huangpu Theatre Theatre speaker sound system connection diagram.
