DMP 44 LC 4x4 Digital Matrix Processor 60-1095-01

The Extron DMP 44 LC Digital Matrix Processor is a compact 4x4 audio mixer featuring a digital signal processing platform for audio signal routing and control. The DMP 44 LC features four line level inputs and outputs, all balanced or unbalanced. It offers several audio DSP tools for mixing, routing, and room optimization. Quick and intuitive configuration using the DSP Configurator™ Software allows the DMP 44 LC to be installed in very little time. The DMP 44 LC is ideal for presentation applications that require line level audio matrix mixing with DSP in a small form factor.

DSP

The DSP built into the DMP 44 LC provides wide dynamic range and utilizes 24-bit audio converters with 48 kHz sampling to maintain audio signal transparency. Several convenient, easy-to-configure tools are available: level controls, high and low pass filters, parametric EQ filters, bass and treble shelving filters, compressor, limiter, and ducker.

Easy-to-Use DSP Configurator Software

The DSP Configurator Software features an intuitive on-screen layout that offers fast access to all of the digital audio signal processing tools as well as 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 44 LC features four mono line inputs that can be matrix mixed into any of the four output buses to create finely tuned audio zones for the corresponding outputs. This audio matrix mixing is ideal for many applications, such as combining two independent stereo audio sources or switchers into a single amplifier or recording system, or in a divisible room installation for feeding a switcher's audio output to the sound system for each room.

Versatile Control Options

The DMP 44 LC can conveniently be controlled and configured via RS-232 serial control or USB. It also includes digital input ports, which allow for external triggering.
