The Class A and amplifiers have the ability to operate in The Class A and amplifiers have the ability to accept
any one of the following modes: either a standard Unbalanced RCA signal input, or a Balanced “Pro Audio” style
Stereo Mono): Use this mode for either stereo operation (left
and right channels) or for Mixed Mono operation (stereo left and channels
plus bridged mono).
input signals with the use of the Soundstream BLT Balanced Line Transmitter or
some other balanced line audio source. Before installing your system, you
should decide upon which signal type you wish to run. There are advantages to
both:
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).
Please follow the wiring schemes below for the correct operation:

The amplifiers’ signal inputs accept a wide range of input level: from
300 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.
the “Unbalanced” RCA Input
When using the Unbalanced RCA input, the (channel 2) input
signal switch 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

the “Balanced” Input
When using the Balanced DIN audio input, both switches in the
“BAL” position. Also, we recommend that when using this input configuration,
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
