I just got a Behringer A500 to power some small DIY 10" subs. I'm using an active crossover upstream of the A500. The high-pass output is going to active loudspeakers, and the crossover is expecting the low-pass amplifier to have a voltage gain of 25x (28 dB). The A500 has gain knobs on the front, but the knobs are only labeled with dots, no unit of measure whatsoever!
For those of you who have used the A500 in your systems, do you have any idea what the gain knobs actually do? I want no gain/attenuation engaged whatsoever - as the spec sheet lists 28 dB as the nominal gain. I could pull out a voltmeter and a test disc, but I was hoping someone could come back with a simple answer like "the knob provides attenuation only; for 28dB gain turn it all the way up."
Thanks.
