Abstract

PURPOSE:To control the output balance of speakers by providing a switching means which can connect the input terminal of a second power amplifier to the input terminal of a first power amplifier. CONSTITUTION:A fader VR 2 is connected between input signal paths of first and second power amplifiers 3 and 7, and a switching means 5 which can connect the input terminal of the second power amplifier 7 to the input terminal of the first power amplifier 3 is provided between the fader VR 2 and the second power amplifier 7. External power amplifiers 14 and 15 can be connected to both terminals of the fader VR 2. That is, the switching means 5 is properly switched to control the output balance of respective speakers by one common fader VR 2 at the time of driving speakers by first and second power amplifiers 3 and 7 as well as using external power amplifiers by BTL connection of both amplifiers.
