Extron DMP 128 Plus C V 12x8 ProDSP Processor w/AEC and VoIP

Product Overview

The Extron DMP 128 Plus C V is a 12-input, 8-output ProDSP digital matrix processor with 64-bit floating point signal processing, six channels of AEC (acoustic echo cancellation), up to eight independent VoIP lines (SIP 2.0), an ACP bus for audio control panels, eight audio file players, a USB audio interface, and configurable macros. It is designed for use in a wide range of room types from single-room credenza systems to large multi-rack and decentralized campus audio systems. Available at Creation Networks.

Product Description

The DMP 128 Plus C V delivers the ProDSP platform in a full-rack 1U processor for installations requiring comprehensive audio signal routing, processing, and control. The 12x8 analog I/O matrix is expanded by an 52x48 mix matrix that incorporates USB audio channels, expansion bus, VoIP channels (V models), Dante channels (AT models), and virtual bus routing. ProDSP provides a 64-bit floating point DSP engine with 24-bit/48 kHz converters and comprehensive tools including level control, adaptive gain, automixing, dynamics, EQ, delay, ducking, loudness, and feedback suppression. The DMP EXP expansion port connects to a second DMP or DTP CrossPoint for 16x16 I/O channel transport to scale audio I/O for larger installations. The ACP bus connects Extron audio control panels for local level and mute control. Eight audio file players support background music and announcements. Available at Creation Networks.

Key Features

• 12x8 ProDSP 64-Bit Floating Point Processor — 24-bit/48 kHz studio-grade conversion; comprehensive DSP tools including EQ, dynamics, delay, ducking, loudness, and feedback suppression.
• 52x48 Mix Matrix — Routes all analog, USB, expansion bus, virtual bus, VoIP, and program sources to any or all outputs.
• Acoustic Echo Cancellation (AEC) — 4 Channels — Extron AEC with advanced convergence algorithms for clear conferencing audio; includes selectable noise cancellation and automatic level control.
• VoIP — Up to 8 Independent Lines (SIP 2.0) — Supports generic SIP 2.0 connectivity for room POTS/VoIP phone integration into the audio matrix.
• USB Audio Interface — Up to 4 channels digital audio in/out for soft-codec computers without additional hardware.
• DMP EXP Expansion Port — 16x16 I/O channel transport to a second DMP 128 Plus or DTP CrossPoint over shielded CAT 6; scales audio routing for larger rooms.
• Eight Audio File Players — Plays background music, announcements, and chime files directly from the processor.
• ACP Bus for Audio Control Panels — Connects Extron audio control panels for local volume and mute control without separate control system programming.
• Configurable Macros — Automates multi-step operations (preset recall, level adjustments, source routing) from a single control trigger.
• DSP Configurator Software — Intuitive Windows-based software for complete DSP routing, processing block configuration, real-time metering, and preset management.
• Ethernet, RS-232, and USB Control — Multiple control interfaces for integration with room control systems.
• Full Rack 1U Enclosure — 1.69" H x 17.40" W x 9.48" D; 4.5 lbs (2.1 kg).

Technical Specifications

Typical Application

The DMP 128 Plus C V is deployed in conference rooms, lecture halls, divisible training spaces, and large council chambers where multi-microphone mixing, conferencing DSP, AEC, VoIP integration must be managed in a single 1U processor with scalable expansion.
