ABSTRACT:
An improved tone control device for controlling a tone within an audio frequency range in a combined mode of fine compensation for frequency characteristic as in the graphic equalizer and coarse tone control as in the bass/treble tone control circuit by making use of corresponding circuits in common for the both control without increasing the scale of circuitry, whereby the audio frequency is divided into N and M (<N) bands and the first manipulation input is fed to each one of the N bands while the second manipulation input is fed to each one of the M bands, the second input is converted into weights for each band in the N bands as by increasing or decreasing the gain thereof with a conversion means and setting the gain of each band by utilizing a gain setting means in accordance with the amount of first manipulation input as well as the weighted gain for an intended tone control.
