Gallo Reference 3 SA Owners

Verbatim beginning at the bottom of page 8..."The volume controls on the SA operate much like a bass tone control on a receiver, except that they're far more precise and allow independent adjustments for each channel. Listening to your favorite albums, you can easily set the tonal balance and the subjective amount of bass exactly to your liking. You could even have multiple settings such as 'flat' for classical and 'fat' for pop, rock, reggae and hip-hop. Why not? It's as easy as turning up the two gain controls by a predetermined amount, so it still sounds coherent, but a little bit stronger in the low bass than is perfectly flat".

Well sure, but the point is that you do have to advance the two level controls from the "Min" (zero) position to get anything out of the amp at all. Your contention that these controls work as tone controls is true insofar only as the SA operates as a LOW BASS control as you advance the level settings. I mean, it's just a subwoofer amp and that's its job.

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?

I run mine at about 1 o'clock. My amp is a DK Design VS I Reference Mk.2
