10 Band Graphic Equalizer

  
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. Each unit has common materials with remainder and it differs only in the capacity of capacitors that constitutes the filter in each unit. 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 [ X1 ]. 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.
