q-factor and general advise on eq section cadac

Hi dear people,


I have a cadac b-series console and i'd like to upgrade the eq section.

1 the q-factor is pretty narrow. Can someone point me out where this can be done in the diagram? Or how to calculate this?
2 if i'd want to change frequency range as well in the midrange, extend it a little lower.
3 I want to hard bypass the hi pass filter. Put the switch at output ic 1B to output 2B
4 Any other tips on this board?

Thanks in advance!
