About this Guide
This guide contains installation, configuration, and operating information for the Extron
DMP128 Plus ProDSP Digital Audio Matrix Processor. In this guide, the DMP 128 Plus may
also be referred to as “DMP 128,” “the mixer,” or “device.”
About the DMP 128 Plus
The Extron DMP 128 Plus Digital Audio Matrix Processor is a 12x8 audio mixer with broad
I/O expansion capabilities including:
• 8 auxiliary inputs via VoIP (V models only), USB, and internal audio files.
• 16 x16 expansion bus
• Dante 48x24 AT channels (AT models only)
• VoIP (V models only)
• Digital I/O
The DMP 128 Plus features Extron ProDSP, automixing, AEC (Acoustic Echo Cancellation),
and USB audio for use as an audio-to-PC interface. The DMP 128 Plus offers a
configuration approach to DSP to simplify mixing, routing, conferencing, and room
optimization. Quick and intuitive configuration using the Extron DSP Configurator software
allows the DMP 128 Plus to be installed in very little time with easy-to-learn adjustments that
can be applied in real-time. A digital audio expansion port (EXP) allows two EXP-capable
devices to be linked together to expand input and output signal management and routing
capabilities. The DMP 128 Plus is ideal for presentation and conferencing applications in
boardrooms, courtrooms, and conference centers requiring advanced matrix mixing and
DSP.
In addition to EXP expansion capabilities, DMP 128 Plus AT models allow connection to a
Dante audio network for transporting audio across a TCP/IP network. This further increases
the DMP 128 Plus input and output expansion capabilities.
DMP 128 Plus V models can register up to 8 VoIP lines per device. The DMP 128 Plus V
can function as a VoIP interface, removing the need for dedicated VoIP hardware.
The DMP 128 Plus has no front panel controls. All configuration is performed using the
Extron DSP Configurator software from a host computer via Ethernet (recommended)
or USB. The rear panel RS-232 port allows for serial control via SIS commands. Signal
presence and clip LEDs for the twelve input channels and eight output channels are on the
front panel. Status indicators for EXP, LAN, and USB audio are also on the front panel.
