Gallo Reference 3 SA Owners

Volume control on SA amp is pretty much personal preference. The manual even indicates that you may want to set the volume control at different levels for different types of music. Mine are set at zero at all times. Spectron amp.

Bostonbean, your SA volume controls are set at zero? How do you get any sound out of it that way?

The "volume controls" work more as tone controls, not for loudness. The SA fills still fills in the lower octaves on your Gallo 3.x's with the so called volume controls set at flat or zero. The manual explains it much better than I can.

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.

I just checked the manual again, Bostonbean, and I can't figure out where you're getting that. We're not talking about the Booster Control but the volume (Level) controls.
