K-03
Commentary

This is a cassette deck that inherits the techniques used in the K 05 and K 04.

GT transport is adopted for the mechanism part.
The GT Transport has a structure that reconsiders the driving system mechanism as a whole and pursues accuracy. The capstan bearing and pinch roller bearing are integrally molded into the motor frame chassis using technology applied to camera body manufacturing, etc. This ensures that the capstan and pinch roller axes are strictly perpendicular to the chassis and that the axes are perfectly parallel to each other.
In addition, the two capstan bearings provide a difference in peripheral speed to give a stable tension to the tape and ensure proper tape touch to the head.

The head part uses LUX original ultra-precision combination head.
With this head, the head gap positions for recording and playback are very close, and the position can be fixed accurately. The K-03 has finished the azimuth adjustment at the time of head manufacturing with accuracy of micron order.

Equipped with 2-speed FF/REW function which adds high-speed FF and high-speed REW.
Also, a music search that automatically searches for and plays a song just by specifying the number of songs you are listening to. By setting the length of the tape in advance, it displays the remaining time of the tape during playback and FF/REW. It is equipped with functions such as a time memory that automatically stops the tape after running it for any time.
It also includes 18 other features such as blank search, auto-space, and MPX filter.
