2 Audio Distribution Amplifier - RB-DA6G
2 RB-DA6G 6 Way Stereo Distribution Amplifier With Output Gain Control
Introduction
Fig 2-1: RB-DA6G Front Panel
The RB-DA6G is a high performance 6 way stereo analogue distribution
amplifier for splitting a source to a number of different outputs.
The RB-DA6P has 1 stereo input and 6 stereo outputs with gain control
on both inputs. It can also be configured so that 1 mono input can be
distributed to 12 outputs. As a variant of the RB-DA6, the RB-DA6G, has an
individual gain control on every output.
On the RB-DA6G the XLR-3 inputs and outputs are electronically balanced
and can be wired unbalanced. Each output is individually buffered so that a
short circuit on one won’t affect the others.
The RB-DA6G has master left and right gain controls which are pre- set
potentiometers accessible through the front panel. Each channel has
an individual output gain control (normalising) which are all pre-set
potentiometers, also accessible through the front panel. The 1-12 mono,
1-6 stereo switch is recessed on the front panel to prevent accidental
knocking. An LED power indicator on the front panel displays the power
supply connection.
