About This Guide

This guide contains installation, configuration, and operating information for the

Extron Electronics DMP 64 ProDSP™ Digital Matrix Processor, software-controlled digital audio processor.

In this guide, the DMP 64 can also be referred to as “the mixer” or “device.”

About the DMP 64 Digital Matrix Processor

The DMP 64 is a standalone audio matrix processor with six microphone/line inputs and four line outputs. Using high-quality 24‑bit A/D converters sampling at 48kHz, input signals are converted into the digital domain where Digital Signal Processing algorithms process and mix the signals using Extron floating point ProDSP™ technology. The DMP 64 uses

a dual‑matrix design providing virtual processing busses, with audio signal processing available in any of the input, virtual, and output signal paths. A dual matrix mixer with virtual paths provides extremely flexible architecture, allowing for versatile processing, mixing, and routing scenarios.

The DMP 64 is IP Link®-enabled, connecting to a host computer via the Ethernet port for fast configuration and setup. Dual RS-232 ports on the rear panel, plus a USB port located on the front panel provide convenient high-speed access. Six digital I/O ports permit connection of switches and sensors to provide input to the system for triggering a variety of actions within the device.

The DMP 64 has no front panel controls therefore, all configuration is performed using the Extron DSP Configurator™ program from a host computer connected by any of the communication ports: RS-232, USB or Ethernet. Signal present and clip LEDs for the six input channels and four output channels are provided on the front panel.

Two operational modes, Live and Emulate, allow a user to work offline from the device to set up a configuration and create presets and group controls as needed before placing the configuration in the DSP 64. DSP Configurator settings developed offline can be saved to disk as a job file to be uploaded to the device at a later time, or can be transferred directly to the device by switching to Live mode. Up to 32 full or partial presets and up to 32 group master controls can be created, loaded into, and stored in the DMP 64. The presets and controls can then be recalled through DSP Configurator, or a control system using Simple Instruction Set (SIS™) commands. Control systems connected to the device either by RS- 232 or Ethernet can control a limited subset of DMP 64 functions using SIS commands.
