The 4CH Digital Audio Processor is a powerful digital audio processor that integrates 4 analog channels and USB sound card functions, designed to meet the needs of modern video conferencing and audio processing. The 4channel Digital Audio Processor uses advanced DSP (digital signal processor) technology and supports a variety of audio processing algorithms, including AEC (acoustic echo cancellation), ANC (active noise reduction) and AFS (automatic feedback suppression), providing users with an excellent audio experience.
1. Analog input channel: 4
2. Analog output channel: 4
3. Built-in two in two out USB sound card, support music playback, recording and soft video conferencing ，Such as: ZOOM, Tencent Conference, Dingding conference, etc.;
4. Two channels independent AEC, tail time: 512ms, convergence rate: 60dB/S, echo cancellation amplitude: 60dB; Independent channel AFC (feedback suppression), using notch algorithm, sound transmission gain increase amplitude: 10dB; Noise suppression (ANS), signal-to-noise ratio increased by 18dB
5. Eight-stage English parametric equalization provides five filter choices:
6. Parametric, Lowshelf, Highshelf, Lowpass, Highpass;
7. Provides customized operation interfaces for terminal users. A maximum of 30 devices can be managed on one interface.
8. With the central control function, support RS232, RS485, UDP three control modes, can be the system power, signal switching, environmental control, audio control and other overall control, to achieve a key to open the system required functions.
