Commentary
Stereo cassette deck with emphasis on basic performance.
Hard WIDEX head is used for the head part.
The WIDEX head uses hard permalloy as a magnetic material, and the head surface is extremely hard and smooth, achieving abrasion resistance approximately three times that of conventional products. In addition, the entire head surface is provided with a special shield to minimize the influence of external
The erasing head uses a double-gap ferrite type with high erasing effect.
A motor equipped with an electronic governor is used for the drive part, and a double belt system with excellent wow flutter characteristics is adopted.
In addition, the main belt is made of flat belt with high processing accuracy to achieve more stable running performance.
Equipped with AMCS (auto-music control system).
If you operate the PLAY lever at the same time in the FF or REW mode, the FF or REW mode will be activated for only the part of the tape where the signal is recorded, and the tape will automatically switch to the PLAY mode at the part where the recording is interrupted. This allows you to start the track.
Equipped with independent 3-stage switching of bias and equalizer that allows you to select the bias and equalizer constant according to the characteristics of the tape.
Equipped with a Rec Mute lever, unnecessary parts can be cut with one touch during recording.
Equipped with a timer standby mechanism that can be used in combination with an audio timer (sold separately) to record messages or play an alarm clock, a headphone output that supports low / high impedance, a full auto-stop mechanism that automatically puts all mechanisms into a free state after the tape has run, and a soft eject mechanism that can be used in combination with a dump mechanism to gently and smoothly take out the tape.
Equipped with various indicators and large level meters.
