Commentary
A twin-tray CD player with two trays.
A twin CD has a structure that has 2 trays on top and bottom, so you can enjoy 2 CDs like 1 CD.
In the twin-tray system, the disc change time is short, and the change time is almost the same as the blank time between normal songs.
One CD can be moved in and out while the other CD is being played. This allows you to play multiple non-stop relay games by changing disks alternately.
In addition, it is also possible to play auto-eject in which one tray automatically retracts and the other tray comes out when play is finished.
You can program play up to 24 songs across DiscI and DiscII.
In addition, you can enjoy multiple program play or random play by using Auto-Eject Play.
It employs a 4 x oversampling digital filter, and the sampling frequency is increased by a factor of 4 to 176.4 kHz by the arithmetic processing of 44.1 kHz. It enables the use of a low-order low-pass filter and realizes low distortion audio characteristics with less phase rotation in the high-frequency range.
Furthermore, the independent D/A converter system on the left and right sides reduces mutual interference and realizes excellent separation characteristics.
In order to protect the optical system mechanism from external vibration, it is fixed to a ceramic mechanical support to reduce unnecessary vibration.
In addition, a honeycomb chassis has been adopted to reduce external vibration.
Equipped with a headphone port with volume.
Equipped with a power on start function that enables timer start.
Equipped with auto program edit function.
