SPEAKER CONFIGURATIONS

Many audio systems can be generated from the three basic speaker output configurations of this

amplifier. They are: 4 CHANNEL MODE (full range audio); 3 CHANNEL MODE (2 channel
pass/l channel low-pass); and 2 CHANNEL MODE (2 channel full-range or low-pass subwoofer).
Possible in-car configurations will be covered elsewhere in this manual.

3 CHANNEL (2

Channel
