Gallo Reference 3 SA Owners

When I tried turning off my main amps and just use the Gallo amp to power the second voice coil I got no sound when the volume control was set to zero. I didn't start getting sound until I started to increase the gain. I think you are supposed to open up the volume controls until you get " a perfectly seamless and invisible level of bass reinforcement". ( Page 11 in the manual). I believe that is what Gallo means as "flat". The way I read it "flat" is not zero on the volume controls. If you want a "fatter sound" then you would increase the volume. If your volume controls are set to zero I think it may be very possible that the Gallo is not doing anything in your system except wasting electricity. Just to make sure I wasn't imagining things I went down and tried it again. With the level set to "min" I got nothing. I didn't get anything until I started to increase the level.

Dopogue, I just don't think Bostonbean gets it. He's confusing flat with zero. In this case flat is not zero. There is a position on the level control where the bass is neither attenuated or accentuated. If you can find that position then you will have a flat response below 40 hz. If you go above that position you may have too much bass, below that position, not enough bass. The reason why Gallo doesn't mark that position on the level control is because it is system and room dependent. That is why you have do the best you can and do it by ear. That is what I asked in my OP. Where are the owners of the Gallo amp setting the level?
