INSTALLATION STEP 2

SELECTING THE SPEAKER OUTPUT MODE

The

Class A 10.2 and 5.2

amplifiers have the ability to operate in

any one of the following modes:

Stereo

Mono): Use this mode for either stereo operation (left

and right channels) or for Mixed Mono operation (stereo left and right channels
plus bridged mono for a subwoofer).

Summed Mono: Use this mode to get a bridged mono output while using both

the left and right inputs and gain controls.

Bridged 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).

Please follow the wiring schemes below for the correct operation:

The

Class A 10.2 and 5.2

amplifiers have the ability to accept either

a standard Unbalanced RCA signal input, or a Balanced “Pro Audio” style input

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:

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.

Using the “Unbalanced” RCA Input

When using the Unbalanced RCA input, the RIGHT channel input signal switch

MUST be 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.
