摘要： 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 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.

摘要翻译： 切换部分使得第一放大部分放大扩展左音频信号并将放大的扩展左音频信号提供给第一扬声器终端，并使第二放大部分放大扩展右音频信号，并将放大的扩展右声道信号提供给 当不使用Bi-Amp功能时，第二扬声器端子。 开关部分使第一放大部分放大用于Bi-Amp的左音频信号，并将放大的左音频信号提供给第一扬声器端子的Bi-Amp，并使第二放大部分放大用于Bi-Amp的右音频信号， 当使用Bi-Amp功能时，将放大的用于Bi-Amp的右音频信号提供给第二扬声器端子。

摘要： In an audio processing apparatus of the present invention, one or two audio signals selected from a surround rear left audio signal, a left outer audio signal and a left upper audio signal is (are) amplified to be outputted from a speaker terminal(s) corresponding to this (these) channel(s) without necessity to provide amplifiers of all channels. When the surround rear left audio signal is included, a switch S13a is turned ON to supply the surround rear left audio signal amplified by an amplifier 12a to a SP terminal 14a. When the left outer audio signal is included, a switch 13b is turned ON to supply the left outer audio signal amplified by the amplifier 12a to a SP terminal 14b, or a switch 13c is turned ON to supply the left outer audio signal amplified by an amplifier 12b to the SP terminal 14b. When the left upper audio signal is included, a switch 13d is turned ON to supply the left upper audio signal amplified by the amplifier 12b to a SP terminal 14c.

摘要翻译： 在本发明的音频处理装置中，从环绕左后音频信号，左外音频信号和左上音频信号中选出的一个或两个音频信号被放大以从扬声器端子输出， 对应于这些（这些）信道，而不需要提供所有信道的放大器。 当包括环绕左后音频信号时，开关S13a被接通以将由放大器12a放大的环绕左后音频信号提供给SP端子14a。 当包括左外部音频信号时，开关13b接通以将由放大器12a放大的左外部音频信号提供给SP端子14b，或​​者开关13c导通，以供给由 放大器12b连接到SP端子14b。 当包括左上音频信号时，开关13d导通，以将由放大器12b放大的左上音频信号提供给SP端子14c。
