A, digital sound processing system is introduced

Digital audio processing system is, in fact also includes digital speakers controller, the system will amplification of peripheral equipment integrated together, form a device, through the function of the digital processing way to complete a variety of equipment, implement quality amplification or record. It greatly simplifies the connection of sound equipment, reduced equipment takes up space, reduce the fault in the process of amplification, feed the system noise, reduce the distortion degree of the voice. At the same time, the input and output are adopting modular, strong interchangeability, easy to maintenance.

At present, many of the world's famous companies have production this kind of audio equipment, such as: the United States DBX company's Drive RackTM PA, 480, 260; EV company DX38; JBL company DSC280: McCauley MCS2.6; Ashly company Protea SYSTEM II 4.24 c; German Behringer company DCX2496; British Xta DP226; Japan's SONY SRP - F300, etc. Some famous speaker manufacturer in order to give full play to its beautiful sound performance and sound quality, specially configured digital speakers controller, including the equipment parts and digital audio processing system is basically the same, the BOSE speakers NEXO speakers such as France and the United States, etc.

Second, the characteristics of digital sound processing system is introduced

1, the input channel 2 and 4 road, every channel arrangements have input level adjustment, input level indicator, A/D conversion, master graphic equalizer, delayer, some feedback suppressor with channels.

2, each output channel configuration the delayer, electronic frequency divider, parametric equalizer, phase shifter, digital level adjustment process, pressure limit, D/A conversion, output level adjustment, output level indicator, retuned buttons.

3, some equipment installed inside the pink noise generator, by measuring the microphone, the real-time spectrum analysis, and use the automatic balance adjustment room isostatic compensation.

4, some machines are equipped with the factory preset and user memory protection, easy to use.

A/(5, has A high precision A/D) and several/modulus (D/A) conversion functions, quantitative ＆#118alue of 24 b, almost can reach 110 db dynamic range.

6, some models are equipped with RS - 232 port connected to the computer, using the software which can adjust the various offers.

7, by matrix circuit connection between input and output, the output channel is less 4 road, more than 10 road, each model is not the same.

8, general MIDI jack, HouGaiBan equipped with digital voice signal processing.

9, some machine is equipped with subharmonic synthesizer, increase the mega bass effect.

10, some still arrange the navigation keys for commonly used power amplifier and speakers provide typical adjusting parameter ＆#118alues.

Generally contains no effect in this system, because a sound source corresponding to the effect of the sound source can only be used for processing, if put it into the system, will appear with a handle multiple sound source sound effect phenomenon, such not only can beautify the sound, to rhyme sound lasting appeal, on the contrary make sound quality to drop, less than using effect is achieved. In addition, don't put the driver into the system, the actuator is often used in the original sound compensation, and compensation amount little, for different sound source, complement harmonic and high component is different, it is used as the necessity of integrated voice sound compensation is not large, so the actuators in the system with little.
