For a very specific project I need a fully parametric 2 bands EQ, with independent Q, Freq. and Gain control, to run on a single rail battery power source (+12v/0v). With 'independent' I mean constant Q and no interactions, pretty much resembling the way DSPs do.
I know this is a lot to ask. I tried already a PCB design based on gyrators but I'm quite unsatisfied with the results, because of interactions and high noise. I need it to be as noiseless as possible, but still running on single a rail.
I see around that popular circuits are NetEQ, Urei 545 or an Elektor design, but the schematics are all for dual rail (+/-18v usually) and I don't know how to adapt them. Any hints or advice will be highly much appreciated!

Domingo
