6 Band Graphic Equaliser Using 741 Op-Amp IC

6 Band Graphic Equaliser Using 741 Op-Amp ICWith this circuit you can control and blend frequencies and tones as desired.Essentially, the circuit consists of an IC 741 whose gain at various freguencies is determined by corresponding potentiometer setting.

The audible frequency spectrum is covered in six steps: 50Hz, 160Hz, 500Hz, 1.6kHz, 5kHz, 16kHz. All potentiometers are of 100k linear type. The circuit provides adequate boost / cut for normal use.PARTS LIST
