This is the circuit of 4 band audio graphic equaliser. The equalizer will cut and boost the four range of audio frequency, that are:
- Low frequency: Freq. 35-680Hz
- Medium frequency: Freq. 150-3kHz
- Medium/semi high frequency: Freq. 450-8.5kHz
- High audio frequency: Freq. 750-15kHz
Circuit note: Use regulated power supply, metalfilm resistor, MKM nonpolar capacitor and tantalum bipolar capacitor for best audio quality result.
