channels 3 and 4 feature a selectable 12db slope on the Highpass setting and 12db or 24db
slope on the Lowpass / Bandpass setting.

network that allows you to select the crossover mode (Highpass—Full Range) and desired
crossover point for channels 1 and 2. Channels 3 and 4 allow you to select between a
Highpass 12db slope, a 12db Stereo Lowpass / Bandpass slope and a mono 24db Lowpass /
Bandpass slope. For example if you wish to drive a pair of subwoofers on channels 3 and 4

control to the desired frequency setting (make sure to have the Highpass control set to
switch to LP/BP stereo. Once the LP/BP stereo switch setting is selected you will use both
