DVDO DVDO-DSP44-1 4x4 DSP Audio Processor

The DVDO DVDO-DSP44-1 is a compact 4x4 digital signal processor designed for professional audio optimization in small to medium sized commercial installations. It delivers flexible routing, mixing, and advanced signal processing for conference rooms, training spaces, and integrated AV environments.

Equipped with four balanced mic line inputs and four balanced line outputs, the processor supports 48V phantom power and a comprehensive DSP engine. Integrated technologies such as Acoustic Feedback Canceler, Adaptive Echo Cancellation, and Automatic Gain Control help maintain clear and intelligible audio in real world conferencing scenarios.

The DVDO-DSP44-1 offers powerful control and integration through RS232, RS485, and Ethernet with intuitive configuration software. Additional capabilities including voice tracking for PTZ cameras and a built in USB audio interface make it ideal for modern conferencing, recording, and hybrid collaboration systems.
