Power Requirements

Operating voltage 14–18 Vdc

Supplied with one of the following external power supplies:

Phantom Power

The P4M does not produce phantom power, but phantom power is allowed to pass through Split Outputs 1–4 to inputs1–4 respectively.

Audio Polarity

All outputs in polarity with all inputs.

XLR Pin 2 is “hot” with respect to Pin 3; Pin 1 is ground. 1/4” TRS tip is “hot” with respect to ring; sleeve is ground.
