ABSTRACT:
A control circuit for controlling reproduced tone characteristics capable of prestoring sound field characteristics to be imparted to a reproduced tone and frequency characteristics of the reproduced tone in combination and reproducing these characteristics simultaneously comprises a sound field characteristics imparting circuit responsive to an input tone signal for producing a sound field effect signal thereby to impart sound field characteristics to a reproduced tone, a frequency characteristics control circuit receiving the input tone signal and outputting the same after controlling frequency characteristics thereof, a memory for storing parameters for setting sound field characteristics to be imparted to the reproduced tone and parameters for controlling frequency characteristics of the input tone signal in combination, and a control circuit for reading out the parameters for setting sound field characteristics and the parameters for controlling frequency characteristics of the input tone signal simultaneously and controlling the sound field characteristics imparting circuit and the frequency characteristics control circuit with the read out parameters to reproduce a sound field.
