Abstract

To reduce signal output and wiring to a D/A converter (DAC). A DAPcomprises a DACthat D/A-converts LRchannels digital audio data into LRchannels analog audio data, an amplification circuitthat amplifies the LRchannels analog audio data that the DACD/A-converts, a DACthat D/A-converts the LRchannels digital audio data into the LRchannels analog audio data, and an amplification circuitthat amplifies inverted LRchannels analog audio data that the LRchannels analog audio data that the DACD/A-converts is inverted.
