Graphic Equalizer Schematic 10 band Mono

Graphic Equalizer Schematic
This really is ten band graphic equalizer for 1 channel (mono) audio program. You will need build 2 similiar circuits for 2 channel (stereo) audio method. This equalizer construct depending on TL074 low sound JFET op-amp that will give you top quality audio output.
