Abstract

PURPOSE:To reduce the heat generation and the power loss and thus to prevent the deterioration of the sound quality for the fader controller which distributes the signals to two units of speakers from the power amplifier, by carrying out the signal distribution through the alternate switching via the high frequency. CONSTITUTION:Square wave signal generation circuit 1 generates square wave signals (a) and (b) of several hunderds ofkHz and the opposite phases to each other, and the variation is secured for the ratio between pulse durations taua and taub. Signals (a) and (b) are supplied to one input end of 1st or 2nd analog switch 2 or 3, and the output signal of power amplifier 4 is supplied to the other input end each. Switch 2 is kept on for the time of pulse duration taua of signal (a); while switch 3 is kept on for the time of taub reach. Through this switching, the contained high frequency component is cut off by high cut filters 5 and 5, and thus the signals distributed in the ratio of taua:taub are supplied to speakers 7 and 8.
