( INSTALLATION STEP 1

SELECTING THE SPEAKER OUTPUT MODE

Channels 1 through 4 of the RUBICON204, 404 and 604 amplifiers have the ability to operate in any one of the following modes:

Stereo @TACT); Use this mode for stereo operation (left and right channels).

Bridged Mono; Use this mode to get a bridged mono output while using only the right channel input and gain control per pair of channels (for use with a singular mono input.)

Please follow the wiring schemes below for the correct operation:

BALANCED / UNBALANCED INPUT

The RUBICON amplifier has the ability to accept either a standard Unbal- anced 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:

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 RlGHT 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 you experience alternator wine or other instal- lation noise with both switches in the “UNBAL”Dosition, trv movinq the LEFT channel inout sicanal switch to the “BAL” position. 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 thatwhen 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:
