Fig 11-3: RB-PMX4 Rear Panel
11.3.1. Inputs 1-10
The XLR-3 input sockets can take balanced professional levels, or unbalanced by using
the front panel gain controls, and by connecting the non-phase to the signal ground
screen. The XLR 3 pin input has the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
11.3.2. Outputs 1-4
The XLR 3 pin output plugs are electronically balanced, and can be wired unbalanced.
Each output is individually buffered so that a short circuit on one output will not affect
the others. They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase

Fig 11-4: RB-PMX4 Front Panel Controls

There are 4 off 10-way switch banks, one for each output. Using these switches, each
input channel can be individually selected to each output. When the switches are up
(OFF) position, they are off and mixed when in the down (ON) position.
Disconnect the mains supply before removing the equipment covers.
