The Extron DMP 44 LC Digital Matrix Processor is a compact 4x4 audio matrix processor featuring a digital signal processing (DSP) platform for audio signal routing, processing, 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 with quick and intuitive configuration using the DSP Configurator™ Software.

NOTE: For full installation, configuration, and operation details, see the DMP 44 LC User Guide available at

Installing the DMP 44 LC

1.Disconnect power from all equipment.

2.(Optional) Mount the unit to a rack or furniture.

3.Connect the audio input. Connect up to four balanced or unbalanced mono line level input devices to line input connectors C above (see the wiring diagram on the right).

4.Connect the audio output. For balanced or unbalanced audio output, connect up to four output devices to line output connectors D above (see the wiring diagram on the right).

5.Connect a control device. Connect a host device, such as a computer, to one of the following DMP 44 LC ports to configure and control the DMP via Simple Instruction Set (SIS™) commands.

•RS-232 port (rear panel) — Connect a host device to the Tx, Rx, and _ (ground) pins of this 6-pole captive screw connector (E). The default baud rate for this port is 38400 baud, 1 stop bit, no parity, 8 data bits, and no flow control (see the wiring diagram on the right).

6.Reset button. The recessed reset button is used to access various modes of resets. The

green power LEDs on both the front and rear panels indicate the reset mode that was accessed. The reset modes are detailed in the user guide.

7.Connect power to the DMP 44 LC by connecting the included 12 VDC external power supply

to the rear panel power connector (see A in the rear panel diagram). The wiring diagram is shown on the right.
