Education series audio all-in-one machine

Descriptions

Adaptive feedback, remote voice echo cancellation digital audio processor developed for normal recording and broadcasting, remote interaction and conference sound reinforcement systems.

The processor has built-in high-quality adaptive feedback (AFC), adaptive echo cancellation (AEC), adaptive noise suppression (ANS), and automatic gain (AGC) voice core processing algorithms;

The 4-in and 2-out processor inputs are equipped with +48V phantom power supply, preamplifier, 4A algorithm, and can be enabled and disabled through the buttons on the front panel.

Processor: ADI SHARC 21489@450 MHz SIMD;

DSP processing capability 400 MIPS, 1.6 GFLOPS;

Sampling rate 48kHz, A/D and D/A 24-bit;

4 balanced microphone/line inputs, supporting 48V phantom power

2 balanced line outputs

2-way AUX loop out

Echo Cancellation (AEC): Tail time: 512ms, convergence rate: 60dB/S, echo cancellation amplitude: 60dB;

Feedback suppression (AFC): feedback suppression tail length: 80-128ms, feedback suppression >65dB,

Noise suppression (ANS): signal-to-noise ratio increased by 18dB;

Automatic gain (AGC): gain increase >16dB;
