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.

This circuit takes single audio Input, you can split stereo audio or you can equalize by two LA3600 ICs. Audio input signal is divided by variable resistors and given to separate base Inputs in the equalizer IC. Finally all base inputs are amplified together by internal op-amp and output audio signal comes out from pin 13.

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 …

the Q of a 2-octave equalizer should be 0.85, and that of a 1⁄ 3-octave equalizer should be 5.1. The response of an equalizer stage with these Q values is shown in Figure 7. A filter with a Q of 1.7 (Figure 7) will have a bandwidth that is 1/1.7, or 0.588 of the center frequency. Thus, the 1000-Hz filter with a Q of 1.7 has a bandwidth of 588 Hz.
