SYSTEM 2 adds an additional amplifier to drive the subwoofers. A RGC-1 (Remote Gain Control) has been added to the subwoofer ampli- fier for dash mounted subwoofer level control.

AMPLIFIER 1

Output is configured for high-pass operation.

Left Phase switch set to 0°

Right Phase switch set to 0°

Gain controls can be set together or independently of each other

AMPLIFIER 2

Output is configured for band-pass operation.

The high-pass crossover is used as a sub sonic filter with INTELLi Q.

RCA inputs are connected to both left and right channels

Left Phase switch set to 0°

Right Phase switch set to 180°

Gain controls must be set identically for both left and right channels.

TUNING NOTES:

Amplifier 1: The phase switches can be individually switched for improved sound quality. Try different phase switch positions for best sonic results.

Amplifier 2: The phase switches can be individually switched for improved sound quality. In the summed bridged configuration the left and the right phase must be set opposite from each other in order to operate correctly. The high-pass crossover is used as a subsonic filter with INTELLi Q. Configure the high-pass crossover for “LOW” frequency range operation and set according to instructions explained in the High-pass Crossover Section in this manual.
