Abstract
PURPOSE:To decrease the number of circuit elements by respectively causing first and second transistors (TR)s to share the role of a buffer amplifier between the volume of right and left channels and a power amplifier so that an opposite channel signal can be mixed to right and left channel signals in an opposite phase. CONSTITUTION:A mixed signal, in which the right channel signal generated from the collector of a second transistor 9 is mixed to the left channel signal generated from the emitter of a first TR 5, is amplified by a left channel power amplifier 8 and outputted. A mixed signal, in which the left channel signal generated from the collector of the first transistor 5 is mixed to the right channel signal generated from the emitter of the second TR 9, is amplified by a right channel power amplifier 12 and outputted. The first TR 5 operates as the buffer amplifier between a left channel volume 3 and the left channel power amplifier 8 and the second TR 9 operates as the buffer amplifier between a right channel volume 4 and a right channel power amplifier 12.
