TONE CONTROL APPARATUS FOR FRONT AND REAR CHANNELS

摘要

A tone control apparatus for a sound system processing audio signals of front and rear channels. By providing front and rear tone control means for independently effecting the tone control in both of the front and rear channels, it is possible to prevent the generation of distortions in the front acoustic output when the control for raising the rear bass level is effected. Also, a tone control balance between the front and rear channels in a vehicle cabin, for example, can be set appropriately.
