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).
