Description
 
It is a cassette deck having an electronic formula digital timer.

The audio timer of the system which aligns with a power supply frequency is built in.
Thereby, practical use as an audio timer and a digital timer to absence recording, an alarm clock play and a sleep play, and external sauce can be performed.

The Dolby system is built in.

The DC servo motor is adopted as a motor.

The tape selector which made the equalizer become independent of bias is adopted, and the engine performance of a normal tape or a special tape can be pulled out.

If the full auto stop mechanism is carried and a tape finishes also in the case of "recording / play / fast forward / rewinding" throat, a pinch roller and a head block will be canceled automatically and a manual operation button will be returned.

Receipts and payments of a smooth tape are possible at soft ejection.

The muting mechanism is carried.
