10 channelequalizer has a range of frequencies at the bass tones from the frequency to 31Hz and treble tone frequency to 16kHz. As an op-amp for the uses a in a symmetrical supply of DC voltage ± 15VDC. IC TL074 is a low noise JFET Op-amp so the equlizer has optimal output quality.
Circuit Of Audio10 CH With TL074
For audio equalizershould have the quality of DC is completely free from riple, therefore the 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.
