4 Audio Distribution Amplifier - RB-DA6R
The RJ45 input is wired according to the StudioHub+ standard and has the
following connections:
Pin 1: Left Phase
Pin 2: Left Non-Phase
Pin 3: Right Phase
Pin 4: Screen
Pin 5: No Connection
Pin 6: Right Non-Phase
Pin 7: No Connection
Pin 8: No Connection
Unbalanced Inputs
The RCA Phono input connectors provide an unbalanced input with an
additional gain of +10dB to compensate for consumer level signals.
Input Selector Switch
This switch controls which input is routed to the outputs; either balanced
(XLR-3 or RJ45) or unbalanced (RCA Phono).
Stereo Outputs 1-6 (Mono Outputs 1-12)
The electronically balanced outputs, which can be wired unbalanced, are
via six RJ45 connectors. Each output is individually buffered so that a short
on one output will not affect the others. They are wired according to the
StudioHub+ standard and have the following connections:
Pin 1: Left Phase
Pin 2: Left Non-Phase
Pin 3: Right Phase
Pin 4: Screen
Pin 5: No Connection
Pin 6: Right Non-Phase
Pin 7: No Connection
Pin 8: No Connection

Input Gain Control
The input gain on the RB-DA6R can
be varied -8dB to +18dB by adjusting
the pre-set potentiometers. These
are accessible through the holes in
the front panel. The RB-DA6R has
separate left and right master gain
controls.
Stereo/Mono Operation
The mode of operation may be switched between a stereo distributed
channel to 6 stereo channels, and a mono channel to 12 mono channels, by
the push button on the front panel, which is recessed to prevent accidental
switching. In mono mode the left input channel is distributed to all outputs.
