Commentary
An adres loaded cassette deck with a detachable wireless remote control.
Comes with a removable wireless remote control.
This remote control is equipped with a special lens filter to increase the sensitivity. Also, it is equipped with a magnet hold. In addition, it can prevent erroneous operation with the rhythmic operation function to check the operation (can be ON/OFF).
The Super AP (High-B Hard Permalloy) head permalloy) head with a high maximum magnetic flux density and a wide magnetic saturation level. Since this head uses a hyperbolic shape, it has excellent head touch, low level fluctuation and low distortion. In addition, abrasion resistance is improved.
The erase head uses a 2-gap AF (Aurex ferrite) head with high erase efficiency.
A 2-motor IC logic new simple mechanism is used for the mechanism part.
In this mechanism, the capstan and reel stand are driven independently to simplify the mechanism. In the automatic take-up mechanism, a swing-head gear drive mechanism has been introduced in place of the conventional reverse idler mechanism. The high-precision gear and the design that does not require friction in the reverse mechanism increases the rotational control capability of the reel stand motor.
In addition, the accuracy of the rotating system is improved by laying out the main rotating shaft on the same chassis, which reduces modulation noise.
Equipped with MQSS mechanism that can be used for head-tracking.
When you want to listen to the next song during playback, this function detects the unrecorded portion before the next song and stops if you fast-forward with it turned ON. It automatically returns to the regenerating condition. When you want to listen to the next song, you repeat it. This function can also be used when rewinding.
This switch also turns ON the MPX filter to prevent malfunction during air check.
As a noise reduction system, it is equipped with an adres unique to Aurex.
As for adres, we have achieved high sound quality by greatly reducing hissing, which was a major drawback of cassette, and expanding dynamic range at the same time, and avoiding bleeding noise and distortion.
You can also play back adres records.
Dolby NR is also installed as a noise reduction system.
± 2 power supply system is adopted.
Equipped with FL electronic digital counter and FL peak program meter.
Equipped with pause / mute function.
In this function, the Rec mute is activated while you press it, and the pause is activated the moment you release it.
It uses a one touch recording method, and recording can be started only with the REC switch.
Timer standby mechanism is adopted.
It has an output volume.
It has a headphone port.
The microphone terminal is mounted on the back.
