The Extron DMP 44 xi Digital Matrix Processor is a compact 4x4 audio mixer featuring digital signal processing with audio signal routing and control. The DMP 44 xi features four line level inputs and outputs, all offering balanced or unbalanced operation. It offers essential audio DSP tools for mixing, routing, and room optimization, such as gain, EQ, and compression. Intuitive configuration using DSP Configurator allows the DMP 44 xi to be quickly and easily set up. The DMP 44 xi is ideal for presentation applications that require line level audio matrix mixing with DSP in a small form factor.

The DSP built into the DMP 44 xi provides wide dynamic range and utilizes 24‑bit audio converters with 48 kHz sampling to maintain audio signal transparency. Several essential, 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 Configuration Software

DSP Configurator software features an intuitive on‑screen layout that offers fast access to all 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 xi 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 xi can conveniently be controlled and configured via RS-232 serial control or USB. It also includes digital input ports, which allow for external triggering.
