With echo canceller and AFC 4CH mini DSP digital audio processor
for classroom or zoom conference
 |
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.
