音乐再生装置
Abstract:
音乐再生装置。本发明的目的是利用简单的结构实现将放大电路的反相输出设置成接地的主动控地。DAP(1)包括：正极侧DAC(7)，其将数字音频数据D/A转换成模拟音频数据；正极侧放大电路(9)，其对DAC(7)D/A转换成的模拟音频数据进行放大；负极侧DAC(8)，其将数字音频数据D/A转换成模拟音频数据；以及负极侧放大电路行放大；以及CPU(2)。在将放大电路(10)的输出设置成接地的ACG模式的情况下，CPU(2)使DAC(8)静音。(10)，其对DAC(8)D/A转换成的模拟音频数据进
Abstract(English):

The invention provides a music reproducing device. 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.
