M-Audio DMP3 [4/10] Rear panel

P3 | User Guide

Rear Panel

1. 9vAC Power Supply Jack: This power jack accepts a 9v AC 1 Amp 2.5mm

power supply. This power supply is included with your DMP3, and ONLY the

proper supply should be used.

2. Output Jacks A and B: These 1/4” TRS jacks are the main outputs for the

pre-amps. Using a TRS (tip-ring-sleeve) 1/4” plug, the DMP3 will provide a

balanced line-level output. Using a TS (tip-sleeve) 1/4” plug, the outputs will

be unbalanced.

3. Phase Inversion Switches: Each switch will invert the phase of the signal for

the selected channel 180 degrees (see section, "Phase Inversion").

4. High Impedance Instrument Inputs A and B: These high impedance (100k

Ohm) inputs are optimized for guitars or high impedance microphones. These

jacks are 1/4” TRS, and will accept either 1/4” TRS or TS plugs (balanced or

unbalanced, respectively). When an instrument is plugged into this jack, the

corresponding channel’s XLR input is disabled.

5. Microphone Inputs A and B: These are the balanced, low impedance

microphone inputs to the pre-amp channels. NOTE: When phantom power is

engaged, power is sent to the ground wire on BOTH of these channels. An

XLR jack is disabled when an instrument is plugged into the corresponding

1/4” jack .
