High Quality Audio Sound System With AEC,AFC 4CH DSP Effect
Proessor
Main Features:
- Analog input channel: 4
- Analog output channel: 4
- 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.;
- 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
- Eight-stage English parametric equalization provides five filter
choices:
- Parametric, Lowshelf, Highshelf, Lowpass, Highpass;
- Provides customized operation interfaces for terminal users. A
maximum of 30 devices can be managed on one interface.
- 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.
The MU44 audio processor is a freely designed audio processing and
control system.
It adopts advanced DSP processing technology, has a new automatic
mixing, Feedback elimination,Echo cancellation,Noise cancellation
etc, targeted to solve various practical problems in the
application scene.
