5 Audio Distribution Amplifier - RB-DA6RG
Balanced Inputs
Balanced professional inputs are provided via dual XLR-3 connectors or the
single RJ45 connector. The two connector types are wired in parallel and
each can take unbalanced signals by connecting the non-phase of each
channel to signal ground (screen). The inputs can be configured as either
stereo, with six stereo outputs, or as mono with twelve outputs.

Input Selector Switch
The XLR-3 pin inputs have the following connections:
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-Phase
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
Output Gain Control
The output gain on the RB-DA6RG can be varied -8dB to +18dB by adjusting
the pre-set potentiometers. These are accessible through the holes in the
front panel. The RB-DA6RG has output gain controls on every output.
