Commentary
An ink-line type cassette deck equipped with an operation system on the inclined surface.
By adopting an ink-line type that incorporates the advantages of top and front operation, we have taken into consideration the balance of performance, operability and durability.
A dolby circuit is installed as a noise reduction system.
It has a queue review mechanism that allows you to fast-forward or rewind a tape in regenerating condition.
Equipped with a full auto-stop mechanism, the operation button is released when the tape is finished regardless of whether recording, playback, fast-forward or rewind.
It is equipped with a memory play mechanism, and automatic heading is possible.
Turn ON the memory switch and set the tape counter to 000. After recording, press Play and REW to rewind to 999. Only REW will be released. The image will be reversed and automatically printed.
It is possible to listen to the same part repeatedly.
The mechanism uses a DC-servo motor with a built-in power generator and a large 94 mm-diameter flywheel. The stable mechanism improves wow flutter characteristics.
It is equipped with a peak indicator that lights up when the sound reaches the level + 5 VU where the sound begins to be distorted.
It uses a tape selector with independent bias and equalizer switching.
Equipped with a timer mechanism, you can record your absence by connecting a timer sold separately.
Ferrite head is used for the head part.
Equipped with a mechanical pause mechanism.
