| 5 band graphic equalizer |
This circuit uses an individual chip, IC BA3812L to realize the five band graphic equalizer for use in HI-FI audio systems. The BA3812L five-point graphic equalizer that has all the necessary functions integrated into one IC. This IC
consists of five tone control circuit and input and output buffer amplifier. The BA3812L features low distortion, low noise and wide dynamic range, and is an ideal choice for Hi-Fi stereo applications. It also has a wide operating voltage range (3.5V to 16V), which means that it can be adapted for use with most types of stereo equipment. The five center frequencies are independently set using external capacitors, and as an output stage buffer amplifier and tone control circuits independent clause, fine control over part of the frequency band is possible, with two BA3812Ls, it is possible to build a 10-point graphic equalizer. The number increases and the cut can be set by external components. The recommended power supply is 8V, but the circuit should work for 9V supply as well. Voltage limit is 16V. Circuit diagram is given in operation for around five frequency bands:
