Abstract

A switching section causes the first amplification section to amplify the expansion left audio signal and supply the amplified expansion left audio signal to the first speaker terminal and causing the second amplification section to amplify the expansion right audio signal and supply the amplified expansion right audio signal to the second speaker terminal when the Bi-Amp function is not used. The switching section causes the first amplification section to amplify the left audio signal for Bi-Amp and supply the amplified left audio signal for Bi-Amp to the first speaker terminal and causing the second amplification section to amplify the right audio signal for Bi-Amp and supply the amplified right audio signal for Bi-Amp to the second speaker terminal when the Bi-Amp function is used.
