Audio Distribution Amplifiers
Audio & Video Interfaces
The RB-DA6G is a 1U rack-mount high
performance 6 way stereo distribution
amplifier for splitting a source into a
number of different outputs. It is identical
to the RB-DA6 with the addition of
individual output gain adjustment, instead
of global stereo gain adjustment.

The RB-DA6P is a version of the RB-DA6 audio
distribution amplifier which uses Neutrik
Phoenix style connectors instead of XLR
inputs and outputs. Each unit is shipped with
the mating connectors so that wires can be
simply terminated using a small flat-blade
screwdriver.
The inputs and outputs are electronically
balanced and can be wired unbalanced. Each
output is individually buffered so that a short
circuit on one output won’t affect the others.
The left and right input gain controls
(normalising) are pre-set potentiometers
accessible through the front panel.
The output gain may be varied from -8dB
to 18dB which is useful for normalising
consumer and
professional signals
to give outputs of
-15dBu and 0dBu
respectively.
