Abstract
To prevent that the noise occurs at timing switching between PCM data and DSD data by a simple configuration. An AV receiverincludes a mute circuitthat mutes output from a DAC, a detection circuitthat detects that a digital audio signal is zero data and supplies a detection signal, a microcomputerthat supplies a control signal at timing switching from PCM data to DSD data before switches from PCM mode that the DACconverts PCM data into an analog audio signal to DSD mode that the DACconverts DSD data into the analog audio signal, and an AND circuitthat activates the mute circuitin case that the detection signal from the detection circuitand the control signal from the microcomputerare supplied.
