Working of Audio Equalizer Circuit: IC UM66 is used in the circuit to alter the melody which is produced by the melody generator. Oscillation is generated by the voltage controlled oscillator at the time when constant voltage is applied. For the purpose of the VCOs phase locked loop IC (i.e. 4046) which is IC1 and IC2 in the circuit is used.

The output of VCOs at the pin 4 of IC CD4046 is a time-multiplexed by a CD4051 multiplexer IC (which IC 4 in the circuit diagram). The signal which is selected for the multiplexer is produced by 555 timer (IC3) which is working as a astable multivibrator. 4.7 is the time taken by the each high as well as low pulse which is upcoming from 555 timer.
Audio Filters: Designing an audio equalizer – Part 7

For this project, we’ll design a three-band, graphic equalizer circuit using audio filters. So, it will have low, high, and band-pass filter circuits to separate the low, high, and mid-range frequencies of the audio signal. The circuits will be active filters using an operational amplifier (op-amps).

Below we present an Audio Graphic Equalizer circuit, based on Philips Semiconductors Application Note 142 (published on October 1984). The circuit itself has great performance and uses a top performance operational amplifier; the NE5532.. The graphic-equalizer consists of an input buffer (IC1 -a), a variable-boost/ cut active filter (lC2-a), and an …
