About the DMP128 Digital Matrix Processor
The Extron DMP128 Digital Matrix Processor is a 12x8 audio mixer featuring
ExtronProDSP, automixing, and I/O expansion capabilities, and is available with
AEC - acoustic echo cancellation plus Dante™ audio networking. The DMP128 offers
a configuration approach to DSP to simplify mixing, routing, conferencing, and room
optimization. Quick and intuitive configuration using the DSP Configurator™ Software allows
DMP128 installation in very little time, with easy-to-learn adjustments heard in real-time.
A digital audio expansion port allows two DMP128 units to be linked together to expand
input and output signal management and routing capabilities. The DMP128 is ideal for
presentation and conferencing applications in boardrooms, courtrooms, and conference
centers that require advanced matrix mixing with DSP.
The DMP128 has no front panel controls. All configuration 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 presence and
clip LEDs for the twelve input channels and eight output channels are on the front panel.
