ok: Im gathering info for building a mixer, and the net has been amazingly helpful thus far. Multiple thanks to those who have responded to my questions. My problem: None of the schematics that I have been directed to/given have involved equalization of the channels. This is rather necessary for my application. What I was thinking of doing is using high, low, and bandpass filters to break the inpuut into three bands and running them through 3/4 of a quad op amp, allowing gain control for each band, and using the remaining op amp for the final gain after recombining the "eq'd" signal. My question: Is this acceptable? Will it work? It seems like a good solution to me, but then it was my twisted mind that thought of it. How do real eq's do it? I have a theory that they do the same basic thing, but use active filters instead of the RC and LRC ones I plan to use. Is this assumption true or way off base? Amy pointers/assistance overwhelmingly appreciated. (In case I wasn't clear enough, the above I intend to use for each channel, as well as the final out, to anyone who might say "You need eq for all the channels!!") Thanks.
