ABSTRACT:
A device for adjusting audio and video signals includes two rotary encoders, one for plural audio adjusting circuits which are arranged to adjust audio signals and the other for plural video adjusting circuits which are arranged to adjust video signals. The rotary encoders are arranged to selectively actuate the plural audio adjusting circuits and the plural video adjusting circuits respectively. The arrangement not only simplifies the operation of the device but also reduces the number of necessary parts.
