name this eq...

[pucho812]

there are 4 in this  rack and said to have come from a console that was at bisou studios now known as grandmaster in Hollywood. I know nothing about them other then 3 band eq LF Shelf, MF peak with medium wide Q, HF Shelf, low and high pass filters. each of the filters is adjustable to various eq points. each eq band has a position frequency switch as well has variable =/- gain, runs off bi-polar psu and it's a combo of discrete and chips. chips run off a max of +/- 22V units are working minus the fact on one the filters cut when engaged but the eq still works.

Maybe you old timers have seen them. The knobs were originally not api knobs but got replaced with api knobs at the request of my client when the psu's was wired up.

yeah, now that you mention it. Hmmm that's possible. the original knobs were the orange round one and then a light grey one but smaller ontop. but they variable hi/lo pass filters are a clue me thinks,never seen that coimbo with eq on any quad eight.
