Digital OUT is an optical output device

This device outputs information from a compact disc in digital
form, making it possible to play music with an external digital
processor or Digital-to-Analog unit. In addition to coaxial out-
put, an optical output device is also provided, eliminating the
interference of noise and improving audio quality.

Anti-vibration Consturction

A double top cover, anti-vibration weighted bottom, sintered
alloy insulators has been used to improve the anti-vibration
effects.

8-cm CD software, to be introduced in the future, can be used.
8-cm CDs can be played without the use of an adapter.
