1. MIC/LINE INPUT Jacks: Accommodate both XLR and 1/4” con-
nectors at mic or line levels. They are electronically balanced.
2. Signal/Clip LEDs: Color indicates the signal status of the corre-
sponding mic/line input:
LED Color Signal Status
Green Signal present
Yellow Nominal Level
Red Signal clipping
3. CONCENTRIC LEVEL/PAN Knobs: The inner knob controls
the input level; the outer ring pans the input signal between the
1/L and 2/R mix outputs.
4. MIX OUT Output Jacks: 1/4” TRS jacks provide the line level
mix created with the level/pan knobs.
5. AUX IN Inputs: Signals from two 1/4” TRS input jacks are com-
bined with the mix created by the level/pan knobs. Front panel
settings do not affect these jacks.
6. DC IN Locking Connector: Plug the PS40 AC adaptor into this
connector.
7. DC OUT Locking Connector: Powers a P4T transmitter or
another P4M mixer. A DC jumper cable is provided with the mix-
er. NOTE: A PS40 can only power two Shure devices.
8. SPLIT OUTPUTS: Each male XLR output provides a duplicate
of its corresponding mic/line input. Front panel settings have no
effect on split outputs.
