12x8 ProDSP™ Digital Matrix Processor

The Extron DMP 128 Digital Matrix Processor is a 12x8 audio mixer featuring Extron ProDSP™, automixing. The DMP 128 Series offers a configuration approach to DSP that simplifies mixing, routing, conferencing, and room optimization. Quick and intuitive configuration using the DSP Configurator™ Software allows the DMP 128 to be installed in very little time, with easy-to-learn adjustments that can be 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.
