~INSTALLATI~N STEP I )

SELECTING THE SPEAKER OUTPUT MODE

The RUBICON Class A 10.2 and 5.2 amplifiers have the ability to operate in any one of the following modes:

Stereo (STACT/Mjx& 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).

( INSTALLATION STEP 2 )

The RUBICON 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 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:

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).

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 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.If vou exDerience alternator wine or other instal- lation noise with both switches in the “UNBAL”position, try movina the LEFT channel inout signal switch to the “BAL”Dosition. This should remove any system noise due to the installation.

Using the “Balanced” RCA Input

When using the Balanced 6-pin DIN audio input, both switches MUST be 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 configuration, see the dia- gram below:
