In 1987, a design was introduced that allowed for smaller enclosures and extended playback time. A structure was created that balances portability and usage time.
D-600
The D-600 is an AC-powered CD player designed for both stationary and in-car use. It employs an internal circuitry similar to that of home CD players and supports headphone and line outputs. It operates on an external power supply and is compatible with in-car power supplies. It does not support battery operation and is not intended for portable use. Its configuration allows it to be used as both a stationary and in-car unit depending on the installation location, making it an example of a portable system from the early days of CD equipment.
In 1987, a practical structure suitable for everyday use was established. At the same time, a design structure based on miniaturization was established.
