Actuator in sound reinforcement system connection?

Sound signal input is divided into two road, all the way through R. Direct output, all the way through the drive level adjustment to the high-pass filter, high pass filter on the tuning knob to acoustic signals in high frequency components given tuning remaining amplified, arrived in amplification of the signal after synchronization harmonic signal generator, the harmonic generator output high-frequency components in phase and amplitude and acoustic signal sound mixing ratio related to the regulation to the acoustic signals, thus making it in the treble and overtone on compensation. At the same time, also increased bass dynamic processing circuit, made on bass, this bass compensation by bass and bass flow control, thus allowing more resonant and more bass. · Exciter in sound reinforcement system how to connect? actuator in sound reinforcement system of connections in two ways: (1) conspiracy into left and right channels, and before the power amplifier, but then after the other peripheral equipment. String into left and right channels, compensation is integrated sound signals, due to the left and right channels in various musical sound and vocal music are mixed together, only for the overall compensation. In the PA amplifier before is because power amplifier frequency response curve best, generally within 10HZ ~ 100KHZ its gain change 0 ~-0.2dB and actuators on the treble and overtone of compensation only 0.5 ~ 1dB, through power amplifier that can become a success rate of the signal, direct drive speaker. If the add-in before other peripheral equipment, most likely because these devices are ideal frequency response performance, compensates the quantity is small in the treble and overtone components are missing, this contact information is usually used in a normal drive level. (2) the use of effect machine and mixer are connected to some or a certain sound signal tone compensation. Because this kind of compensation is in the vicinity of a mixer, so must adopt the high level of motivation, to power amplifier in the response. Debug methods are as follows: (1) close the OVERHANG and GIRTH knob, so that compensation for treble and overtone, bass masking treble. (2) press the IN/OUT keys to actuator access voice channel and TUNE knob is placed in the position of the "12 points". (3) from small to large, adjust the MIX knob, listen, until you hear a chrome, (double). (4) adjust TUNE knob again to enable sound clear and bright. (5) will MIX knob at a slightly lower position, not banded. (6) open GIRTH knobs and adjustment knob to OVERHANG the bass was rich, yet not turbid. (7) the knob to adjust the GIRTH is full-sounding bass.
