摘要： An amplifying device is provided that reduces power consumption and quickly starts amplification of an audio signal of a channel to be used. A control section 17 inputs a control signal for instructing operation or standby into post-amplifying sections 11b and 12b, and inputs a control signal for instructing standby to post-amplifying sections 13b and 14b. In the post-amplifying section 11b, when the control signal for instructing standby or operation is input from the control section 17, a modulation circuit 52 modulates the analog audio signal into a switching signal. An output stage circuit 54 amplifies the output signal. When the control signal for instructing the operation is input from the control section 17, a driving circuit 53 drives the output stage circuit 54 in response to the switching signal, and stops the driving of the output stage circuit 54 when the control signal for instructing standby is input.
