Fixed Architecture DSP
SR-DSP12
12-channel matrix-mixing DSP audio processor — automatic mixing, AFS / AEC / ANC, built-in USB sound card.
A dual-core, 32-bit floating-point DSP processor with comprehensive matrix mixing and a built-in automatic mixing console (AM), plus feedback (AFS), echo (AEC) and noise (ANC) cancellation. Every input provides preamplifier, signal generator, expander, compressor and 5-band parametric EQ; every output a 31-band graphic equalizer, delay, crossover and limiter. Controlled from a built-in web page, PC client or multiple platforms, with camera tracking and USB sound-card connectivity for Zoom, Teams and other video conferencing.
