- Page 7 The RUBICON amplifiers incorporate an on-board staggered electronic cross- over, with RCA outputs (RUBICON only) to drive an external electronic crossover is necessary. However, if you do desire to use an external crossover you still have that option. The high and low pass portions of the crossover can be set independently of one another.

Page 8: Installation Step
The circuit consists of two controls. One engages a sub- sonic High Pass filter at 45 Hz, and the other adjusts the of boost (0 to +9 dB) (fixed at +6dB for the RUBCON & 355). The Boost control adjusts the amount of level applied at the set frequency, and is adjustable from 0 to +9 dB (see figure 2). -

INTERNAL The RUBICON255, 355 81 555 amplifier are fused with automotive-type fuses. In the event of blown power supply fuses, replace with the correct value fuse found in the chart below. Never replace the fuse with a higher value than what is sup- This may result in amplifier damage and will void the warranty! plied. -

INSTALLATION STEP 4) SEmlNG LEVEL The input levels are adjusted by means of the input level controls located on the front of the amplifier. This is a unique dual-stage circuit that adjusts both level and gain. This topology maintains better S/N Ratio even when using minimal output. - Page 11 SAMPLE SY$TEllU #2 -All channels of input 4 channels of 2-way high pass, (rear de-emphasis engaged on 555) subwoofer channel in low pass SOUNDI- G?Yh” TOP VIEW +12V REMOTE GND FUSE ‘I FRONT VIEW TOP VIEW CHANNELS 3=4 CHANNELS 1 +12V GND REM - L + - R + I ___ __.~~.
