because I'm an idiot. sorry, I can't see the pic you put up and I was going by fuzzy internetz pics.. I just read that it can bp by using the subsonic filter and lpf together. there should be a pdf download of the manual somewhere online that can guide you.
On channels 3&4 set the x-over switch to "LP/BP" set the subsonic dial to 63hz set the other switch to "x-10" and set the dial to 3.5khz. If you want channels 1&2 bandpassed too set the x-over switch to "Clone 3/4CH".
