Audio Amplifier and Graphic Equalizer 2 Design using Opamps
https://course.ece.cmu.edu/~ee321/spring00/lab2.pdf
Graphic Equalizer Design using Opamps Introduction In this lab you will design, construct, and test an opamp-based audio amplifier and 3-band graphic equalizer. Figure 1 shows the block diagram of the system that you will build. The graphic equalizer will span the audio frequency band (20Hz - 20kHz). If you are using your own Discman/Walkman, make sure that it delivers

Tone control or Active equalizer circuit especially bass, treble, and MID control based Equalizer is an important circuit in audio amplifier design. Generally, three-stage active Equalizer filters require three control bass, treble, and MID. The bass control allows the low frequency to pass but blocks high frequency and the treble control allows the high frequency to …
Audio Filters: Designing an audio equalizer – Part 7
https://www.engineersgarage.com/audio-filters-designing-an-audio-equalizer-7-8/
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).
Audio Equalizer Circuit using LA3600 - circuits-diy.com

An audio input signal is separated into resistors and provided in the equalizer IC for separate base inputs. Finally, the internal op-amp amplifies all base inputs, and pin 13 outputs the audio signal. The circuit can be made more professional with a slide potentiometer instead of a Variable Resistor.

The output might be disrupted due to overlapping of signals obtained from different sources and to avoid that a suitable quality factor (Q) must be selected, doing so introduces coloration into the audio signal. The band graphic equalizer circuit is constructed using two cheap and good quality operational amplifiers which are readily available in the …

In this audio equalizer, we use the LF351* op amp. It is an integrated circuit and it uses an 8-pin dual in-line package, which can easily plug into the breadboard. There is no specific ground connection. For our circuit, use op amp power supply voltages of 12V for the positive terminal (pin 7), and ground the negative power terminal (pin 4).
