About this Guide
This user guide contains installation, configuration, and operating information for the Extron DMP 44 xi.
NOTE: Throughout this guide, the general terms "DMP," and "processor" are used interchangeably to refer to
the DMP 44 xi.
About the DMP 44 xi
The DMP 44 xi, digital audio matrix processor, is a compact, standalone audio mixer with four line-level inputs and
four line-level outputs. It features a digital signal processing platform for audio signal routing and control and
offers several audio digital signal processing (DSP) tools for mixing, routing, and room optimization. All
configuration of DSP processors and the matrix mixer is performed using the Extron DSP Configurator Pro from a
host computer via RS-232 or USB communication ports.
Two operational modes, Live and Emulate, allow for working offline from the DMP to set up a configuration and
create presets and group controls as needed before loading the configuration to the processor. DSP settings
developed offline can be saved to the disk as a configuration 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 user presets and up to 16 group
master controls can be created and stored on the DMP. Control systems connected to the DMP 44 xi by RS-232
or USB can control a subset of device functions using Extron Simple Instruction Set (SIS) commands.
Features
•
4x4 line level digital audio matrix mixer — The DMP 44 xi is a compact matrix mixer with DSP. It features
four line level inputs that can be processed, mixed, and routed to four line level outputs.
•
Inputs: Four balanced or unbalanced line level on two 3.5 mm, 6-pole captive screw connectors
• Outputs: Four balanced or unbalanced line level on two 3.5 mm, 6-pole captive screw connectors
•
Digital audio signal processing on all inputs and outputs
• Expanded dynamics and filter DSP blocks — Comprehensive dynamics block includes compression,
limiting, AGC, gating, and ducking. Filter DSP includes 4th order HPF/LPF.
• DSP Configurator Pro provides an intuitive graphical user environment — A powerful and user-friendly
PC-based software tool for managing all audio operations of the DMP 44 xi. It enables complete setup and
configuration of digital audio processing tools with a clear view of all inputs and outputs, audio processing
blocks, routing, and mix points in a single window.
•
Four digital input ports for remote triggering — Four configurable digital input ports are provided, so that
external switches and sensors can be connected to the mixer for remote triggering of functions within the
DMP 44 xi.
•
Predictable, low latency hardware DSP — Input to output latency is fixed within the DMP 44 xi, regardless
of the number of active channels or processes. Predictable, low latency processing keeps audio in sync with
video, and prevents distractions to a presenter resulting from delayed live audio.
