This circuit uses a single chip, IC MAIN BEARINGS MS226P to achieve a 5-band graphic equalizer for use in Hi-Fi audio systems. The 5-band graphic equalizer is true for radio-cassette players, stereos and car radios. The device features: low distortion and low noise, high power voltage range (3.5V to 16V), low dissipation current (5 mA), Wide Dynamic Range (HOV 2.1Vrms/VCC = = 8V), and built in input and output buffer amplifier.
The MAIN BEARINGS MS226P is a five-point graphic equalizer that has all the necessary functions integrated on a single integrated circuit. The IC is equipped with five channels of sound control and input and output buffer amplifier. The pdf file below contains detailed information on circuit diagrams for the 5-band equalizer with a single IC / chip (MAIN BEARINGS MS226P). The circuit is given in the scheme around the five frequency bands: 100Hz, 300Hz, 1kHz, 3kHz, 10kHz
