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.

Features

4x4 line level audio matrix mixer — The DMP 44 LC is a compact matrix mixer with DSP. It features four line level inputs that can be processed, mixed, and routed to four line level outputs.

Inputs: Four balanced or unbalanced line level on two 3.5 mm, 6-pole captive screw connectors

Outputs: Four balanced or unbalanced line level on two 3.5 mm, 6-pole captive screw connectors

DSP audio signal processing — The DMP 44 LC provides digital signal processing on all inputs and outputs.

24-bit/48 kHz analog-to-digital and digital-to-analog converters — High performance converters preserve audio signal integrity in input and output signal conversion, while maintaining latency under 1 ms.

Fixed, low latency DSP processing — Input to output latency is fixed within the DMP 44 LC, regardless of the number of active channels or processes. Fixed, low latency processing keeps audio in sync with video, and prevents distractions to the presenter resulting from delayed live audio.

DSP Configurator™ Software — A powerful yet user-friendly PC-based software tool for managing all audio operations of the DMP 44 LC. It enables complete setup and configuration of digital audio processing tools as well as routing and mixing.

Intuitive Graphical User Environment — The DSP Configurator Software features a Graphical User Environment that offers a clear view of all inputs and outputs, audio processing blocks, routing, and mix points in a single window. This allows a designer or installer to quickly view an audio configuration without having to access multiple windows or menus.

Front panel USB configuration port — Enables easy configuration via the DSP Configurator Software without having to access the mixer's rear panel.

RS-232 control port — Using serial commands, the DMP 44 LC can be integrated into a control system. Extron products use the SIS™ - Simple Instruction Set command protocol, a set of basic ASCII code commands that allow for quick and easy programming.

Building Blocks processor settings — A collection of pre-designed processor settings optimized for a specific type of input or output device, such as microphones and Extron speakers, with preset levels, filters, dynamics, and more. Flexible Building Blocks are available on each I/O strip and allow system designers to fully customize and save their own Building Blocks, further streamlining audio system design and integration.

Console View with gain settings, metering, and routing in a single window — An optional view within the DSP Configurator Software that allows system designers to see all gain settings and routing, together with live metering in a single window. Console View provides overload indication, numeric values for levels, and also mute status for each input, gain stage, mix point, and output, so that settings between inputs and outputs can be easily compared and adjusted in one view.

Three digital input ports for remote triggering — Three configurable digital input ports are provided, so that external switches and sensors can be connected to the mixer for remote triggering of functions within the DMP 44 LC.

Live and Emulate operation modes with configuration file saving — Live mode allows integrators to connect to the DMP 44 LC and make live parameter adjustments while hearing or metering them in real-time. This avoids the need to compile and upload a configuration file to the DSP. Emulation mode allows settings to be configured offline, then uploaded to the DMP 44 LC. The software also downloads configuration files from the mixer for archiving.

16 DSP Configurator presets — Using the DSP Configurator Software, any or all parameters for DSP processing, levels, or audio routing can be saved as presets.

Group masters — The DMP 44 LC provides the capability to consolidate gain or mute control throughout the system. Gain or mute controls can be selected and added to a group master, which can then be controlled by a single master fader or mute control. Up to 16 group masters can be created.

Soft limits provide optimal group master adjustment range — The group master volume range can be limited using soft limits to maintain optimal minimum and maximum levels when using external volume control. This prevents operators from over or under-adjusting levels when using digital input or RS-232 control. The DSP Configurator Software provides quick drag-and-drop adjustment of soft limits from the Group Controls screen.

SpeedNav™ keyboard navigation — SpeedNav enables user-friendly, keyboard-based navigation of the DSP Configurator Software without the need for a mouse or touchpad. Using keyboard navigation keys and shortcuts, the user can access any input or output, mix point, and all audio DSP tools. Using only the keyboard for software access can help expedite audio system setup and optimization while on-site using laptop PCs.
