ABSTRACT:
A tone control circuit is provided having several parallel channels each of which comprises an electronic potentiometer. In each of the channels is disposed a filtering element. Thus, for an output terminal common to the different channels, each of the channels comprises a filter comprising a series element corresponding to the series element of this channel and a parallel element corresponding to the series elements placed in parallel of the other channels. The present invention simplifies the construction of tone control circuits in the form of integrated circuits.
