Abstract
There is provided an audio amplifier, including: an AV signal acquisition unit that acquires an AV signal; a television connection unit to which a television receiver is connected; a first audio amplifying circuit to which a speaker is connected; and a control unit. The control unit transmits to the television receiver a command to shut off power for a second audio amplifying circuit of the television receiver when outputting the video signal of the AV signal acquired by the AV signal acquisition unit from the television connection unit toward the television receiver and when inputting the audio signal of the AV signal to the first audio amplifying circuit. The control unit shuts off power for the first audio amplifying circuit when outputting the video signal and the audio signal of the AV signal from the television connection unit toward the television receiver.
