3 Band Equalizer - Circuit Diagrams
http://www.circuit-diagrams.net/page/3-band-equalizer
A tone control circuit made with a single op-amp and having three ranges, bass, middle and treble controls. Notes: Using a single op-amp this easy to make equalizer offers three ranges, low frequency,mid frequency,and high. With component values shown there is approximately +/-20dB of boost or cut at frequencies of 50Hz, 1kHz and 10kHz.

With a 3 band equalizer we break up the spectrum in three sections. the bass for the low sounds; the mid for the mid range; the treble for the high frequenceies ; For each of these 3 bands, we create filters in our circuit to control their respective audible volumes. You can pump up that low frequency bass sound or increase those treble high ...
