About the DMP 64 Digital Matrix Processor

The DMP 64 is a standalone audio matrix processor with 6 microphone/line inputs and 4
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
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 of DSP processors
and mixing matrixes is performed using the Extron DSP Configurator program from a host
computer via any of the communication ports, RS-232, USB or Ethernet (high-speed ports
recommended). 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, and then
recalled through the DSP Configurator or a control system using 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.
