Carvin BX1500 Para EQ/Freq Sweep -Help

[vinxbass]

I just received my BX1500 and need some pointers on how to use the High Mid,Mid and Low Mid freq sweep controls. I know a little about frequencies, but really don't understand them when it pertains to this complex amp. I'm looking for suggestions, thank you.

Plug in, turn knobs, listen.

I didn't need the eq complexity/biamp capabilities, and sold mine a few weeks ago. I had been a longtime Carvin owner/operator, but I tired of the reliability issues of Carvin in general.

Yep that's pretty much it. Listen to what each control does so you can compensate effectively when you get out on a stage.

As others have said, play around with the knobs to get your own idea of how they work. Go easy on the boost, especially with a hollow body, ABG, or upright, unless you are purposely looking for a very colored sound.

There are lots of threads here talking about frequency ranges to cut or boost. Here are some suggestions you can use for a starting point.

Low Mid: a modest boost around 100-120 Hz makes for a fat sound. It's easy to overdo, and many bass cabs already have a hump in the response here. Go to lower frequencies for a reggae rumble, but watch the power if your cab isn't built to handle the low lows.

Mid: Try a cut (scoop) at 450 Hz or so. IMHO it smooths out the tone. Also makes room for the singer in the mix. Try it flat and scooped and see for yourself. This range overlaps with the Contour control of the BX heads.

High Mid: a slight boost somewhere between 800 and 1.2K Hz adds some "definition" to your attack.
