DVDO 4x4 DSP Audio Processor

DVDO-DSP44-1 is a compact, high-performance digital signal processor with four balanced analog inputs and four balanced analog outputs.

It is designed for small to medium-size commercial audio installations requiring flexible routing and mixing as well as advanced signal optimization.

It features advanced audio technologies including Acoustic Feedback Canceler (AFC), Adaptive Echo Cancellation (AEC), Adaptive Noise Suppression (ANS), Automatic Gain Control (AGC), Active Noise Cancellation (ANC) & Auto Mixer (AM).

Its configurable DSP engine supports EQ, dynamics, filtering, delay, summing and full matrix routing, all controlled through an intuitive software interface or via RS232/RS485.

Additional features include voice tracking for PTZ cameras, a USB port for audio recording/playback & video conferencing, and front-panel status indicators.
