Radio cassette player with World Wide Twin Tuner.

Equipped with a World Wide Twin Tuner with two independent tuners.
The tuner comes with two tuners : a home area for daily use and a travel area for travel. You can preset seven TV/FM/AM songs in both areas, so you don't have to fix your preset memories when you return from a trip.
Frequency and step switching for each area of Japan / North America / Europe and the world can be easily performed while viewing the LCD.

Equipped with an automatic memory scan function, you can automatically preset local broadcasting stations in various parts of Japan with one touch operation.

The main body is equipped with a vertically sliding hold shutter.
When the shutter is closed, it automatically enters the HOLD state, preventing operation errors such as accidentally touching the button.

Equipped with the Automatic Music Sensor (AMS), you can find the beginning and end of one song by simply pressing the FF/REW button during Play. This function can be operated from either the remote control or the console.

Equipped with a newly developed comfortable volume switch (A. V. L. S) as a limiter function.
This function constantly monitors the state of the music signal during playback and controls the volume emitted from the headphones so that it does not exceed the point of sound leakage.

Uses a sound swing guard mechanism (anti-rolling mechanism).
This mechanism was designed by analyzing the dynamic characteristics of vibration from the viewpoint of the moment of inertia of the flywheel and the stability of the motor. It maintains a stable rotating state even when subjected to vibration while walking, and reduces sound vibration.

It is equipped with the A side / B side notification function, and you can check whether the A side or B side of the tape is being reproduced and how the tape is running with the LED on the body.

Uses a 0.8 mm thick cassette lid.

A la carte headphone system is used for the remote control part, and the newly developed ultra-small micro plug is used for the remote control part so that the headphone can be replaced. The plug / jack part is gold-plated.

An EX amorphous head is used for the head part.
This head uses amorphous material and an EX mechanism with a special tape guide that keeps the angle between the head and the tape constant.

Equipped with a Dolby B type noise reduction system.

Equipped with an EXD. B. B. (Dynamic Bass Boost) circuit, you can enhance 50 Hz bass by up to 16 times.
In D. B. B., the emphasis is automatically adjusted according to the position of the volume knob at that time. In addition, in EX D. B. B., the amplification amount is linearly changed according to the volume change of the original sound to prevent the sensitivity of the weak sound from being lost.

Equipped with an auto tape selector.

Equipped with a 10 minute quick charge function, it can be charged up to 50% of full charge in 10 minutes and fully charged in 30 minutes.
It automatically switches between fast charging and normal charging according to the remaining amount of the rechargeable battery.

In addition to black, there are gray and blue as color variations.
