• 

3+4 = Input signal on channels 3+4 are routed to channels 1+2.  Use this mode when you need a band pass filter

CHANNELS 3 & 4 CROSSOVER CONFIGURATION

• 

Flat:  Full Range Signal.  No crossover filter used.

• 

HP:  Activates the High Pass filter.

• 

LP/BP:  Activates the selection of either a Low Pass filter for woofer or a Band Pass filter for midrange.

• 

MONO Mode:  Inputs 3+4 are mixed to mono for bridge mode operation.  If 1+2 ROUTE is set to COPY then 1+2 

will also be mono subwoofer and the remote volume control will control level. 

The subwoofer remote volume control is activated.  There is a clip distortion light on the remote volume control. 

If you see this light on, reduce volume until the light goes out so that you do not damage your speaker. 

AUTOMATIC POWER TURN ON/OFF

1. 

The best way to automatically turn the amplifier power on and off is to use the REM wire from your source radio 

connected to the REM amplifier terminal.Band Pass for a subwoofer or midbass of a 3 way speaker.

2. 

If your original equipment stereo or source radio has a BTL amplifier then the RCA inputs have an auto turn 

on sensing circuit.  When you connect the high level BTL speaker wires to the RCA input the REM wire is not 

necessary.
