| Zusammenfassung: | An amplification apparatus comprises: an amplifier circuit (4) that amplifies an input audio signal and outputs an output audio signal; a first signal level determining unit that determines whether or not a signal level of the output audio signal outputted from the amplifier circuit (4) is lower than a silence determination reference value; and a power-supply control unit (7) that shifts the amplification apparatus from a power-on state to a power-off state, when the first signal level determining unit determines that the signal level of the output audio signal outputted from the amplifier circuit (4) is lower than the silence determination reference value. |
