6-Band Graphic Equalizer

The EQ-2 it is a circuit of graphic equalizer 6 band of regulation. Each band is regulated from the

potesometers RV1-6, that are, for better optical indicate of regulations, Fader. This does not mean

that we cannot him replace with simply potesometer. In the center of regulation potesometer, the
gain is null (flat), but in terminal has +/- 15 db, boost or cutting off, respectively. For stereo

operation, it will be supposed two times.
