Audio Equalizer 10 CH With TL074

10 channel audio equalizer has a range of audio frequencies at the bass tones from the frequency to 31Hz and treble tone frequency to 16kHz. As an op-amp for the equalizer 10 channels uses a TL074 IC in a symmetrical supply of DC voltage ± 15VDC. IC TL074 is a low noise JFET Op-amp so the audio equlizer has optimal output quality.

Circuit Of Audio Equalizer 10 CH With TL074

For audio equalizer circuit power supply should have the quality of DC is completely free from riple, therefore the power supply for audio equalizer should at least use a voltage regulator chip and double-capacitor filters. The quality of power supply is intended to get the audio quality and low noise output and hifi from audio equalizer 10  channel of this.
