[ INSTALLATION STEP 1

The RUBICON Class A Pf@ISSO and RWOIR amplifiers have the ability to operate in any one of the following modes:

Stereo (STACT/Mxed Mono): Use this mode for either stereo operation (left

I

and right channels) or for Mixed Mono operation (stereo left and rigIht channels

 

plus bridged mono).

 

[ INSTALLATION STEP 2

The RUBICON Class A PlclclSS0 and EIUOIR 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:

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).

Please follow the wiring schemes below for the correct operation:

UNBALANCED tNPUl

1.Most preamplifier / source units have

ADVANTAGES Unbalanced RCA outputs (Industry Standard).

2.No Interface module is necessary.

*

BALANCED INFUT

1.Improved Signal to Noise Ratio (S/N Ratio).

2.Excellent noise cancellation characteristics.

3.Immune to noise radiated in the car audio environment.

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 vouexDerience alternator whine or other installation noise with both switches in the “UNBAL”r>osition, trv movincl the LEFTchannel input sianal switch to the “BAL”Dosition. This

should remove any system noise due to the installation.

U&g the “Balanced” DIN Input

When using the Balanced 6-pin DIN audio input, both switches MUSTbe 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 configura-

FAQ

What are the operating modes for RUBICON amplifiers?

The RUBICON amplifiers have the ability to operate in Stereo STACT/Mxed Mono or bridged mono modes.

What signal inputs can the RUBICON amplifiers accept?

The RUBICON amplifiers can accept either standard Unbalanced RCA signal input or Balanced Pro Audio style input signals using the Soundstream BLT Balanced Line Transmitter or other balanced line audio source.

How should I adjust the input level controls for the RUBICON amplifiers?

For the best S/N ratio, it is recommended to set the input level controls as far down as possible rotated counter-clockwise, while maintaining an acceptable level of output.
