SR-CM02-DSP
Digital audio signal processor — the cascade hub and DSP engine for the SR-CM02 microphone array.
SR-CM02-DSP is a professional digital audio signal processor built on dedicated embedded architecture for precise, low-latency volume control and mixing. It cascades up to 6 SR-CM02 digital microphone inputs plus 4 linear inputs over simple PoE, USB and Phoenix-terminal wiring, and applies a full audio-processing suite — automatic noise suppression, gain control, echo cancellation, equalization and intelligent microphone mixing — to keep conferencing audio clear. It also converts Dante network audio to analogue output and provides an extended wireless microphone input.
