Abstract
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 sectioninputs a control signal for instructing operation or standby into post-amplifying sectionsand, and inputs a control signal for instructing standby to post-amplifying sectionsand. In the post-amplifying section, when the control signal for instructing standby or operation is input from the control section, a modulation circuitmodulates the analog audio signal into a switching signal. An output stage circuitamplifies the output signal. When the control signal for instructing the operation is input from the control section, a driving circuitdrives the output stage circuitin response to the switching signal, and stops the driving of the output stage circuitwhen the control signal for instructing standby is input.
