Inputs (Left and Right)
The XLR-3 input connectors can take balanced professional levels, or unbalanced by using
the front panel gain controls, and by connecting the non-phase to the signal ground. The
input can be congured as either a stereo input with six stereo outputs or a mono input
with twelve outputs. The XLR 3 pin input has the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Stereo Outputs 1-6 (Mono Outputs 1-12)
The XLR 3 pin outputs are electronically balanced, and can be wired unbalanced. Each
output is individually buered so that a short circuit on one output will not aect the others.
They have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Input Gain Control (RB-DA6)
The input gain on the RB-DA6 can be varied –8dB to 18db by adjusting the pre-set
potentiometers. These are accessible through the holes in the front panel. The RB-DA6 has
separate left and right master gain controls.

Output Gain Control (RB-DA6G)
The output gain on the RB-DA6G can be varied –8dB to 18dB by adjusting the pre-set
potentiometers. These are accessible through the holes in the front panel. The RB-DA6G has
output gain controls on every output.
