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
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
