Extron DMP 128 C P - 12x8 ProDSP Processor with AEC and POTS

Product Description

The Extron DMP 128 C P ProDSP processor is a 12x8 digital matrix processor with eight independent channels of high-performance Acoustic Echo Cancellation and an integrated POTS analog telephone interface, engineered for audio conferencing and sound system management in commercial AV environments. Built on Extron ProDSP 64-bit floating point technology with 24-bit, 48 kHz audio conversion, this DSP processor combines 12 mic/line inputs, eight line outputs, an eight-group automixer, and comprehensive per-channel signal processing in a single 1U enclosure. It is well suited to boardrooms, courtrooms, council chambers, lecture halls, and conference facilities that require clear, echo-free conferencing audio and flexible signal routing.

The eight channels of AEC deliver convergence up to 60 dB/sec with selectable noise cancellation up to 20 dB, keeping far-end participants free of echo and background noise during teleconferences. The built-in POTS interface initiates and receives calls over a standard analog telephone line, allowing legacy telephony to participate in modern conferencing systems, while a digital audio expansion port supports integration with computer-based and soft codec applications. Comprehensive DSP, including filtering, equalization, dynamics, delay, mixing, and gain control on every channel, gives integrators precise control over each signal in the room.

The DMP 128 C P is configured and monitored using Extron DSP Configurator software, which provides drag-and-drop signal flow design, real-time metering, and preset management, and it integrates with Extron control processors over Ethernet and RS-232 for unified room control. Commercial AV buyers building a complete control and audio system can pair this processor with an Extron control processor such as the Extron IPCP Pro 350 xi, and can browse related audio and control hardware in the Extron collection.

Key Features
