Commentary
Double cassette deck with 10-track random program and quick reverse recording mechanism
It is equipped with Dolby HX Pro which applies active servo bias theory.
The Dolby HX Pro keeps the total effective bias constant by adjusting the bias to a deep level when there is a large number of mid - and low-frequency components and to a shallow level when there is a large number of high-frequency components. As a result, the saturation phenomenon of tape, which is easily caused by high-level high-frequency signals, is suppressed, enabling clear recording.
Also, Dolby HX Pro works only when recording, so it can be played on any deck.
Equipped with a 10-track random program function that allows you to freely specify the order of up to 10 tracks to be played.
Equipped with double-speed dubbing function.
A recording / re-quick reverse mechanism is adopted, and a 0.2 second quick reverse is realized by a rotary head system.
Equipped with a multi-functional electronic counter that allows you to enjoy repeated playback between any two points.
Equipped with an editing mechanism that can be used for rerecording.
With this function, you can play the tape in reverse while the switch is pressed, and when you release the switch at the desired point, the auto-rec mute function activates and automatically creates a 4-second inter-song blank and enters a pause standby state.
Equipped with a blank skip mechanism, the deck automatically begins to fast-forward when an unrecorded portion of the tape continues for more than 12 seconds and moves from the beginning of the next song to the playback.
Equipped with a one push recording function.
