should decide upon which signal type you wish to run. There are advantages to
both:
Brr’dged Mono; Use this mode to get a bridged mono output while using only
the right channel input and gain control (for use with a singular mono input).

The
RUBICON
amplifiers’ signal inputs accept a wide range of input level: from
300
mVrms
to 5.0 Vrms for both Balanced and Unbalanced inputs. For the best
S/N Ratio, we recommend that the input level controls be set as far down as
possible (rotated counter-clockwise), while maintaining an acceptable level of
output.
Using
the “Unbalanced” RCA Input
When using the Unbalanced RCA input, the RIGHTchannel (channel 2) input
signal switch MUSTbe in the “UNBAL” position. Also, when first installing the
amplifier using this input configuration, we suggest that the left channel input
signal switch be in the “UNBAL” position as well. If vou exDerience alternator

When using the Balanced

the input level controls be set to the “minimum” position (rotated counter-
clockwise). The system gain should then be adjusted on the BLT Balanced
Line Transmitter, other other balanced line audio source. For the pin
