Commentary
Stereo cassette deck equipped with configuration mechanism and convenient mechanism.
In order to improve the stability and durability of the transport part, a smooth operating system that does not impose an excessive load on each mechanism part is adopted.
A gear drive system that converts rotational motion into linear motion, a roller system is used for the head slide chassis, polyacetal resin is used for the slide contacts to minimize friction, and a balanced back tension system is used for the tape drive system that constantly balances the load applied to the mechanism and the head touch with the total balance of the spring.
Uses a 38-pulse FG servo motor.
In addition, stainless steel (SUS420J) is used for the main parts such as the capstan, pinch roller fulcrum, idler lever, and drive lever shaft. The capstan is made of high-precision stainless steel with a roundness of less than 0.05 μ m. The bearings are made of high-purity copper-based oil-less metal. In addition, special polishing flat belt and a center-driven reel spindle that rotates around the center of the cassette hub are used to increase the stability.
Equipped with bias fine adjustment mechanism for LH tape.
This mechanism can be used in the LH position of the bias to improve the sound quality of normal tapes with narrow high frequencies or to compensate for the sound of LH tapes.
In addition to the VU meter, it has a 3-step peak indicator.
Green at -1dB, yellow at + 3 dB, and red at + 7 dB.
Equipped with a timer standby mechanism. If an optional timer is connected, you can record your absence or play an alarm clock.
Equipped with Rec mute function with muting time indicator.
Ferrite guard head is used for the head.
Equipped with Dolby system with built-in MPX filter.
Equipped with a synchronous operation mechanism.
Includes Quick Review Queue functionality.
Equipped with a pure electronic full auto-stop mechanism.
It has a playback volume.
Mic (L + R) jack is mounted.
Oil dump / eject system is adopted.
Equipped with a tape illumination lamp.
