About This Guide

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

Extron DMP 44 LC Digital Matrix Processor, software controlled digital audio processor.

In this guide, the DMP 44 LC may also be referred to as “the DMP” or “device.”

About the DMP 44 LC Digital Matrix Processor

The DMP 44 LC is a standalone audio matrix processor with four line inputs and four line outputs. Using high-quality 24‑bit A/D converters sampling at 48 kHz, input signals are converted into the digital domain where Digital Signal Processing algorithms process and mix the signals. The DMP 44 LC uses a matrix design providing audio signal processing available in any of the input and output signal paths. A matrix mixer provides extremely flexible architecture, allowing for versatile processing, mixing, and routing scenarios.

An RS-232 port on the rear panel, plus a USB port located on the front panel provide convenient high-speed access. Three digital input ports permit connection of switches and sensors to provide input to the system for triggering a variety of actions within the device.

The DMP 44 LC has no front panel controls, therefore all configuration of DSP processors and the matrix mixer is performed using the Extron DSP Configurator™ program from a host computer via the RS-232 or USB communication ports.

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 DMP 44 LC. DSP Configurator settings developed offline can be saved to disk as a job file that can be uploaded to the device at a later time, or can be transferred directly to the device by switching to Live mode. Up to 16 full or partial presets and up to

16 group master controls can be created, loaded into and stored in the DMP 44 LC. Control systems connected to the device by RS-232 can control a subset of DMP 44 LC functions using Extron Simple Instruction Set (SIS™) commands.

Features

•Consumer and professional audio compatibility — Line inputs provide gain settings to accommodate consumer (-10 dBV) and professional (+4 dBu) operating line level sources.

•Inputs — Four balanced or unbalanced line on 3.5 mm, 6-pole captive screw connectors.
