• Converts music signals (analog voltage waveform) from the audio unit to digital signals, then amplifies and outputs them.
• The 2-channel (left and right) audio signals are converted to simulated 5-channel in the audio amplifier and output to each speaker. Due to this, surround sound can be enjoyed with the source from a 2-channel recorded CD.
