Look at the attached image. See that little "wishbone" thingy at the top of the frequency selection knob? And see the sort of "Double Wishbone" next to it? What does that indicate, and how do I use it? Understand I have only cursory understanding of parametric EQ's.

The one that looks like a wishbone is indicating that it is a low shelving type of EQ and the rotary dial underneath it adjusts the freq at which it hinges. The one that looks like an eye to the right of it is a peaking type of EQ and its dial selects the center freq of what will either be boosted or cut. With the peaking type, if it's true parametric there would be a "Q" control as well which adjusts how wide of a freq will be affected when you apply boost or cut. With the shelving type, the "Q" control is how steep the edge of the shelf will be (dB/octave).
 
Thanks Track.
Let me see if I understand then.
The closer it is to the "small part of the wishbone" the tighter the hinge? and the less "spread out", over that portion of frequency spectrum, the EQ effect will be?
I have something similar to this in a plug-in, and I can graphically see the effect on an EQ graph, the symbols look a little different though, and I just wanted to be sure I knew what was going on.
 
I'm not sure what you mean by a "Q" control, but here's a pic of the whole thing.

There would only be a "Q" control if it was true parametric. Otherwise, the width of the filter is not adjustable, only the frequency and amount of cut and boost are.

OK, how do I know which direction cuts or boosts?
 
Along with the frequency rotary control there should be another one paired with it that is the boost/cut control. At its 12:00 position, it should indicate "0", or no boost or cut. Turning it clockwise should boost whatever frequency it coresponding freq control is set to, counter-clockwise, a cut.
 
I was just looking at the picture you attached and there only appears to be one boost/cut control and its center is not at 12:00 like most units I've seen but at about the 4:00 position.
 
Hmmm,,, ok, well the inner rotary dial's range is about from 11:00 to 1:00 (not quite a full circle) so I'm thinking maybe 6:00 is "0"?

OK cool.
 
Ah Ha! I was just able to make out that there are concentric dials. Yea, 6:00 is 0 ranging from 11:00 to 1:00. Sorry, the lic is kind of soft.
