The circuit diagram below shows a circuit of graphic equalizer 6 band of regulation. The potentiometer RV1-6 regulates each band, and the sliding type is the recommended for better visual indication. . The gain is null (flat) in the center position of potentiometer, but in the maximum and minimum position has +/- 15 dB, boost or cutting off, respectively. It […]

Below is a classic circuit of regulation of tone of three way. With this circuit, we can regulate low, mid and high frequencies of acoustic signal. We can regulate the boost/cut in the range of +- 18 dB/oct. The supply on the the circuit is 15V, but it can be supplied with 9 until 30V. It’s enough to connected pin […]
