Abstract

PURPOSE:To increase the spread of the reproduction sound as well as the ambience by providing the desired delay time difference among the reproduction stereo signals produced through plural number of speakers by means of the balancer resistor of single operation plus the stereo signal delay part. CONSTITUTION:The right and left stereo signals supplied to terminals 1 and 1' are supplied to delay parts 2FR and 2RR plus 2FL and 2RL each. The delay time of parts 2FL-2RL are decided by repetitive frequency fc of the clock pulse generated at clock pulse generation part 3 plus delay parts 2FL-2RL composed of the charge transfer elements. And the delay parts supply the input stereo signals to power amplifier part 5 with the delay time mentioned above. Frequency fc is varied by the resistance value of resistor 4, and the resistance value is changed according to the turning direction of a piece of the knob. Accordingly, the control can be given to the arrival time of the reproduction sound sent from the ambient speakers even in the comparatively narrow space. Thus the spread of the reproduction sound and the ambience can be increased.
