Audio Graphic Equaliser

Posted on Jan 6, 2013

Audio graphic equalizers are very common as commercial products (for Hi-fi, car audio and stage use) but circuits for them are very rarely published. I didn`t design this one but it`s really very simple. The details shown are for a 7 band but the principle can be extended to almost any number of bands - if you can find accurate enough components.
