Main Stereo Inputs (Left and Right)
The XLR-3 input connectors can take balanced professional levels, or unbalanced by using
the volume control to increase the input level, and by connecting the non-phase to the
signal ground. The input can be conīgured as either a stereo input with two stereo outputs
or a mono input with two mono paired outputs. The XLR 3 pin input has the following
connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-phase
Stereo Input Gain Adjustment (RB-HD1)
There are two preset controls on the rear panel that adjust the level of the master input
signal to the outputs from -12dB to +20dB gain.
