摘要： To reduce signal output and wiring to a D/A converter (DAC).A DAP 1 comprises a DAC 7 that D/A-converts LR 2 channels digital audio data into LR 2 channels analog audio data, an amplification circuit 9 that amplifies the LR 2 channels analog audio data that the DAC 7 D/A-converts, a DAC 8 that D/A-converts the LR 2 channels digital audio data into the LR 2 channels analog audio data, and an amplification circuit 10 that amplifies inverted LR 2 channels analog audio data that the LR 2 channels analog audio data that the DAC 8 D/A-converts is inverted.

摘要： To realize active control ground that sets inverted output of an amplification circuit to ground with simple configuration.A DAP 1 comprises a positive side DAC 7 that D/A-converts digital audio data into analog audio data, a positive side amplification circuit 9 that amplifies the analog audio data that the DAC 7 D/A-converts, a negative side DAC 8 that D/A-converts the digital audio data into the analog audio data, and a negative side amplification circuit 10 that amplifies the analog audio data that the DAC 8 D/A-converts, and a CPU 2. The CPU 2 mutes the DAC 8 in case of an ACG mode that sets output of the amplification circuit 10 to ground.
