10-Band Graphic Equalizer

Posted on Feb 6, 2014

This circuit allows you to equlize the audio signals in 10 band. It uses low amount op-amps (TL074 - JFET op-amp) to anatomy a able blaster circuit. The affection of the architecture is a classical band-pass alive filter. The VCC is in ambit of 12 ~ 15 VDC and The VDD is in ambit of -12 ~ -15 VDC respectively. As shown in the diagram, there are 10

same units that only differ in capacitance values of capacitors which determine the frequency band of each filter. The potentiometers adjust the predetermined regions of frequency in each unit. If it is intended for stereo use then it will be supposed it is made in two pieces with as much as possible suited the materials, between the channels, so that do not exist differences in the regulation of each band frequencies. Switch S1 isolates the circuit EQ, when him we did not need and it ensures level [ flat ] response in the exit of circuit. The circuit should be connected between preamplifier and in a final power amplifier.
