10 Band Audio Equalizer


Posted on Aug 28, 2012

This circuit allows you to equlize the audio signals in ten band. It uses low cost op-amps to form a professional equalizer circuit. The heart of the design is a classical band-pass active filter. The U11 acts as an attenuator to prepare the signal level for equlizing.
