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.
