Commentary
A CD player with digital output.
Equipped with an optical digital output.
The D/A converter is equipped with a hybrid pulse D/A converter.
The Hybrid Pulse D/A converter has a built-in noise-shaping digital filter that performs high-precision oversampling operation in the D/A converter itself, simplifying the signal path by making it into a single chip, and improving the effect of the direct digital sync circuit formed in the chip, reducing signal degradation due to jitter.
The servo circuit of the optical pickup is equipped with a high-precision digital servo.
This circuit uses a high sampling rate A/D and D/A converter to achieve servocontrol that better reflects the disc condition.
It is equipped with a custom edit function, such as a time edit function to edit a song according to the length of a tape or disk and a time fade function to edit the end of a song.
It also features a peak search for the highest recording level on the disc, a program edit of up to 24 steps, and a manual fader.
Equipped with a delete shuffle function, you can leave only the music you want to listen to and play it randomly.
Equipped with 3-way Music Scan, you can play only the beginning part of the song in order.
Equipped with a timer function, timer playback is possible by combining with an external timer.
Equipped with a headphone port with volume.
Wireless remote control is included.
