Abstract

PURPOSE: To enable to fit the audio image by monoral audio signal from a plurality of speakers to arbitrary direction, by the interlocking control of the control of delay time and the control of audio volume with a given relation.
CONSTITUTION: As the frequency of the clock generator C is increased, the delay time of audio signal passing through the delay element D is shorter, and the audio signal level obtained with the output terminal Oa with the voltage controlled amplifier A controlled with the voltage converted with the clock signal simultaneously is increased. Further, on the contrary, when frequency is lowered, the delay time is longer and the output audio signal level is smaller. Accordingly, by controlling the variable resistor VR1 or VR2 for the sliders L1 or L2, between the output signals Sa and Sc and the output signals Sb and Sd, the phase delay and the magnitude of the audio level can reversely be changed. As a result, when control is made by using the controller controllable the two variable resistors, the audio image can be fixed to arbitrary direction.
