Extron DMP 128 Plus12x8 ProDSP Processor

Product Overview

The Extron DMP 128 Plus Series is a family of 12x8 digital matrix processors built on the ProDSP 64-bit floating point processing platform. Six models provide 12 mic/line inputs, 8 line outputs, USB audio, and configurable aux channels — with C models adding 12-channel AEC, AT models adding Dante audio networking, and V models adding up to 8 SIP 2.0 VoIP lines. Available from Creation Networks.

Product Description

The DMP 128 Plus Series is designed for conference rooms, training facilities, and multi-room AV systems that require professional-grade audio signal processing, conferencing capabilities, and flexible routing. All models feature 12 balanced/unbalanced mic/line inputs (8 with 48V phantom power), 8 balanced/unbalanced line outputs, a configurable USB audio interface, an EXP port for linking two DMP 128 Plus units over shielded CAT 6, and an ACP port for Extron audio control panels. The ProDSP engine provides 64-bit floating point processing at 24-bit/48 kHz with automixing (gated and gain-sharing, up to 8 groups), EQ, dynamics, delay, adaptive gain, ducking, loudness, and feedback suppression. C models add 12 independent channels of AEC with selectable noise cancellation up to 20 dB, certified for Microsoft Teams Rooms and Zoom Rooms. AT models add Dante/AES67 networking with 48 Rx and 24 Tx channels and FlexInput. V models add up to 8 concurrent SIP 2.0 VoIP lines. All models include 32 configurable presets, 16 virtual processing loops, digital I/O, RS-232, Ethernet, USB control, and an Extron Everlast internal power supply.

Key Features

• 12 Mic/Line Inputs, 8 Line Outputs — 12 balanced/unbalanced inputs (8 with 48V phantom power) and 8 balanced/unbalanced line outputs in a 1U full-rack enclosure.
• ProDSP 64-Bit Floating Point Processing at 24-bit/48 kHz — High dynamic range DSP with <0.02% THD+N, S/N >107 dB, and half the latency of the previous generation.

Technical Specifications

Typical Application

The DMP 128 Plus Series is deployed in conference rooms, boardrooms, training facilities, courtrooms, and multi-room AV systems requiring professional audio DSP, automixing, and flexible signal routing. C models are the preferred choice for videoconferencing applications requiring AEC. AT models suit campus and multi-building deployments with Dante networking. V models add integrated VoIP conferencing without a separate dial-up codec.
