•Outputs — Four balanced or unbalanced line on 3.5 mm, 6-pole captive screw connectors.

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

•DSP audio signal processing — The DMP 44 LC provides digital signal processing on all input and output paths.

•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.

•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.

•Building Blocks processor templates — A collection of pre-designed processor templates 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.

•Live and Emulate operation modes with configuration file saving — Allows settings to be configured offline, then uploaded to the DMP 44 LC. The software also backs up configurations from the device for archiving.

•Low latency DSP processing — The DSP engine supports an array of concurrent audio processing within an audio channel and across multiple channels, while maintaining extremely low latency from input to output.

•DSP Configurator Software — Powerful, user-friendly PC-based software tool for managing all audio operations of the DMP 44 LC. The software 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 with a clear view of all input and outputs, audio processing blocks, routing, mix-points, and virtual routing in a single window. This allows a designer or installer to quickly view all audio activities without having to access multiple windows or menus.

•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, a user can access any input or output, mixing points, and all audio DSP tools. Using only the keyboard for software access can help expedite audio system setup and commissioning while on-site using laptop.

•Copy and paste for processing blocks — To help speed up audio system design and setup, parameter settings can be quickly copied between individual processing blocks or identical groups of blocks within the graphical user environment, using conventional cut-and-paste commands.
