Commentary

Reverse deck with a dbx system.

Equipped with a dbx system that achieves a high dynamic range by recording a music signal compressed to 1 / 2 and stretching it to 2 times during playback. In addition, with a 3 nr configuration equipped with Dolby B/C, you can choose the appropriate NR according to your purpose.

The reverse mechanism has an inversion detection function using an infrared sensor.
There are three types of reverse mode : single-sided, double-sided, and double-sided loop. The direction of tape movement can be switched by the direction selector.

The newly developed thrust hold AX rotary head is used for the recording and reproducing head.
This head uses an AX head made of an amorphous alloy, and has a thrust hold rotary structure that eliminates misalignment of azimuth in the forward and reverse directions, so that uniform characteristics are obtained over A and B surfaces.

With a built-in music selector, you can start the next song by pressing the FF key while the tape is playing, and start the current song by pressing the REW key.

It is possible to repeat one song.

Built-in functions such as blank skip and auto REC mute.

Equipped with an auto tape selector that automatically detects the type of tape and changes the position of the tape.

Equipped with a timer standby mechanism.

There are silver and black color variations.
