Description
 
The compact disk player which carries functionalities, such as a preset editing.

The super clean digital filter original with an audio circuitry is carried.
This circuitry is adopting newly developed 96th digital filter MN6618A, and also combining a high precision analog low pass filter, and has removed the unnecessary noise component thoroughly, without spoiling an audio property. It not only raises a phase response and the frequency characteristic by this, but it is raising the tone quality on Hearing impression.

The high precision FF-1 laser pickup by 1 beam scheme original with technics is adopted as a pickup part.
An FF-1 laser pickup has a high utilization factor of laser light compared with 3 conventional beam schemes, and has improved the SN ratio of a regenerative signal sharply.

The oscillation which has an ill effect on a tone quality is prevented by carrying out the floating of the whole traversal mechanism.

The preset editing functionality is carried.
In this functionality, since the residual time of a tapes will calculate and will be displayed when the WAIT TIME MODE key is pressed on the way if the music to edit after setting the enrolment time of the tapes to be used is programmed, it is easy to edit the music corresponding to residual time.

The high speed linear-access system which adopted the high precision linear motor as the actuator of the traversal mechanism to which a pickup is moved is adopted. Furthermore, the servo system using the newly developed microcomputer has realized the high-speed head search for an average of 1.0 seconds.
Moreover, in this system, deceleration mechanisms, such as a gear belt, are lost and silence and an endurance are also improving.

The 6-figure function-logic-diagram multi-display in which 4 mode windows of the lapsed time of all songs, residual time and the lapsed time in performance music, and residual time are possible is carried. Moreover, the attenuation of a digital attenuator can also be expressed as this display device.

Functionalities, such as a 20 music random special NetWare program, a skip / manual search, one music / all songs / special-NetWare-program repeat, are carried.

Wireless remote control with a ten key is attached.
The digital attenuator functionality is carried in this remote control, and a sound volume can be adjusted with a level key every 2dB from 0dB to -12dB.
