Circuit of 31 channels
From a simple design a single channel, it will be developed into 31 channels with the way potentiometer in parallel. This is done because it makes the design a more modest considering the number of channels created. Images from the series of graphic equalizer which in parallel are as follows:
Circuit of 31 channels
In the figure above, each channel works on its center frequency itself so that no effect if the parallel between each potentiometer. This is because the potentiometer is in parallel to work as a band pass filter. Schematic of the circuit which will be created that is 31 band graphic equalizer
mono which would then be made of two found on the following image:
Circuit of 31 channels
By combining the graphic equalizer and a potentiometer circuit connected in parallel as much as 31 it is obtained a potentiometer 31 band graphic equalizer. This technique is used so that noise generated can minimized because it does not go through many processes. From the above schematic drawings which is a series of mono will be made again so that one circuit a 31 band stereo graphic equalizer.
