Abstract
An amplification apparatus comprises: an amplifier circuit 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 is lower than a silence determination reference value; and a power-supply control unit that shifts the amplification apparatus from a power-on state to a power-off state, when it is determined that the signal level of the output audio signal outputted from the amplifier circuit is lower than the silence determination reference value.
