Commentary
A cassette deck with improved operability and sound quality using D. P.S. S. and amorphous heads.
The head is equipped with a newly developed amorphous alloy head.
A ribbon-shaped thin amorphous alloy head is completed when a ferromagnet such as iron or cobalt and a semimetal alloy such as a semiconductor are rapidly cooled in a molten state.
This head has high saturation magnetic flux density and high magnetic flux density can be obtained with a small magnetic field, so it can record high-quality sound with high efficiency. It also has excellent insulation properties. The head can be made as thin as 50 μ m, so it has low overcurrent loss and a wide frequency band with an extended high-frequency range.
Equipped with 1D. P.S. Tape travel can be freely operated.
You can instantly select up to 15 songs, randomly select songs that can be registered in the order you want to listen to, various auto operations linked with counter index, auto mute, skip one song, repeat one song, etc.
With built-in RAM, you can select up to 15 songs of your choice and register and play the songs on one side of the tape in any order you like.
Automatic operation is also possible, such as one repeat of the song you want to listen to, or one side full repeat of a BGM tape for a long time by registering in order from the first song to the second and third songs.
A microcomputer servo 2-motor mechanism is used to ensure stable tape travel.
Equipped with a large twin VU meter with a 3-point peak indicator.
Equipped with mechanisms such as 4-stage switching tape selector, ± 20% adjustment mechanism with center click, Dolby NR with MPX filter switching, timer standby, etc.
