3 Audio Distribution Amplifier - RB-DA6P
Connections and Operation
Inputs (Left and Right)
The Phoenix style 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 configured as either
a stereo input with six stereo outputs or a mono input with twelve outputs.
The connections are shown in Fig 1-8.
Stereo Outputs 1-6
(Mono Outputs 1-12)
The Phoenix style 3 pin outputs are
electronically balanced, and can be
wired unbalanced. Each output is
individually buffered so that a short
circuit on one output will not affect the
others. The connections are shown in
Fig 3
-4.
Input Gain Control
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.
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.
