Power Requirements
Operating voltage 14–18 Vdc
Supplied with one of the following external power supplies:
S
Model PS40: 120 Vac, 60 Hz input
S
Model PS40E, Model PS40UK: 230 Vac, 50/60 Hz input
NOTE: Courtesy DC connector is protected from short by a self–resetting
“Polyfuse”. Maximum recommended load is 250mA. (2 P4Ms or 1 P4T.)
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.
