Front/Rear configurations
Channels are driven by PC36 (PC36 always takes signal from IN1)
Sub is driven by IN1 + IN2 NO FADING SUB (with active Constant Bass)
Multichannel Configurations
Channels are driven by PC36 (PC36 always takes signal from IN1).
Sub is driven by IN1 + IN2.
IN2 = Sub level: Sub is driven by IN1 + IN2. Fader is used to adjust sub level.
IN2 = Not used: Sub and Front driven by IN1.
