The circuit should be connected between preamplifier and in a final power amplifier. Switch S1 isolates the circuit EQ, when him we did not need and it ensures level response in the exit of circuit. The seven band graphic equalizer IC is a CMOS chip that divides the audio spectrum into seven bands. This circuit takes a single audio input and allows you to divide stereo audio or equalize it using two LA3600 ICs. These potentiometers are used to change the output of each band. 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. Working Explanation This circuit is designed to work with a 12-volt power source, with capacitors and potentiometers separating five distinct bands. The quality of all materials should be very good. On the contrary if it is moved to the side of entry, the rung acts as filter of passage of area, strengthening the signals of predetermined area of frequencies. ![]() On the contrary if the runner is moved to a side of exit, the unit acts as filter of cutting off of area and it degrades the signals of predetermined area of frequencies. A typical graphic equalizer consists of several audio filter/amplifiers, each centered at a specific frequency in the audio range. When the runner of fader regulation RV1 until RV10, is in the middle then we do not have no intervention of filter above in the signal that passes from in his and gain of particular unit, is one. ![]() ![]() Each unit has common materials with remainder and it differs only in the capacity of capacitors that constitutes the filter in each unit. The circuit of graphic equalizer, allocates ten adjusting potesometer, that each one from them affects in a predetermined area of frequencies, the central frequency of which abstains a octave (double), from the central frequencies of her neighbouring regions. Audio Equalizer Circuit Simple Audio equalizer circuit constructed by using famous 5 band graphic equalizer IC LA3600, this is a monolithic linear IC from sanyo.
