Can anyone explain to me what exactly this is? Its found under the custom equalizer settings. Theres Gain -6 to +6, Frequency 60, 120, 180, and Q 1, 1.25, 1.5, 2.0. Also the Mid has the same Q to adjust, but the treble doesn't.

I've actually had the unit (an 835 I believe) for a few years, but finally got the rest of the amps and subs hooked up, so I'm tweaking now.

Thank you for all your expert help and guidance,

Lorne

Q factor in an EQ is the center frequency divided by the bandwidth. It determines the slope of the EQ curve at its peak, or the steepness of the "knee." Higher Q means you are controlling a narrower band with the boost or cut of the EQ. Lower Q means the control functions over a wider effective area. High Q is useful for cutting out particularly bothersome peaks or resonances, low Q works more like a traditional "bass" "midrange" and "treble" control.

Thank you very much... That was quite helpful. I'm going to go out to my truck and try playing with it right now. Thanks again,

Lorne

Just for my record then, if its set at 1-Q and the centre frequency was 60, that means its pretty much adjusting from 30 to 90 Hz, and if it was at 2-Q it would be 45 to 75?

but if I changed the frequency to 180, my gain control would be boosting from 90 to 270 hz at 1-Q, or 120 to 240 at 2 -Q

That would be correct.
