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 .
