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.
