DMP 64 6x4 ProDSP Processor 60-1054-01

The Extron DMP 64 Digital Matrix Processor is a 6x4 audio mixer featuring Extron ProDSP™, a powerful digital signal processing platform for audio signal routing and control. The DMP 64 offers a configuration approach to DSP that simplifies mixing, routing, and room optimization. Quick and intuitive configuration using the DSP Configurator™ Software allows the DMP 64 to be installed in very little time, with easy-to-learn adjustments that can be heard in real-time. The DMP 64 is ideal for presentation applications that require advanced line and microphone audio matrix mixing with DSP in a small form factor.


Extron’s exclusive ProDSP is engineered from the ground up using a powerful 64-bit floating point DSP engine to provide very wide dynamic range and reduce the potential for clipping. ProDSP also utilizes studio grade 24-bit audio converters with 48 kHz sampling to maintain audio signal transparency. ProDSP is loaded with powerful, easy-to-configure tools to control level, dynamics, filters, delay, ducking, loudness, and feedback suppression.

Easy-to-Use DSP Configurator Software

The power of ProDSP is easily harnessed with the DSP Configurator Software. The flexible on-screen layout offers fast access to all of the digital audio signal processing tools including level control, dynamics, filters, delay, ducking, loudness, feedback suppression, and matrix mixing. Designers can quickly get a snapshot view of the entire audio system, including processing blocks and routing assignments, all at once.

Flexible Routing

The DMP 64 features six mono mic/line inputs with phantom power. These inputs can be matrixed mixed into any of the four output buses to create finely tuned audio zones for the corresponding outputs. In addition, the six inputs can also be routed to any of the four “virtual” buses to allow inputs to be processed together as a group, before routing back into the output buses. The flexible routing capabilities within the DMP 64 allow system designers to create various signal management schemes to accommodate a variety of sound system application requirements.

Versatile Control Options

The DMP 64 can conveniently be controlled and configured via RS-232 serial control, Ethernet control, or USB. It also includes digital I/O ports, which allow for external triggering such as mic activation and muting.
