The compact disk player which adopted virtual
battery operation, and advanced MASH and 1-bit DAC.


Virtual battery
operation is adopted as a power-source part.
This power circuit is a
circuitry developed using the property of MOS-FET to the maximum extent, and
high-quality sound-ization is attained by cutting the wraparound of the noise
from a power source or a digital circuit.


In order to reduce the ill
effect to the tone quality by the oscillation from the outside, the newly
developed THCB vibration proof design is adopted.
With this structure, the
external oscillation is cut with an effective combination of a steel plate and a
viscoelasticity object.


Newly developed advanced MASH and 1-bit DAC are
adopted as a D-A-conversion part.

By the differential circuit of 8DAC stream compositions, the noise component
was cut and high S/N, the low distortion, and the high linearity are realized.
Moreover, the high order accuracy and the high fidelity play are investigated
by adopting as a differential circuit the instrumentation circuitry currently
used for the measuring instrument etc.


The digital servo is adopted.
In this
circuitry, the fluence of an electric current is stopped to the minimum by
adjusting to the amount of servoes which was proper and was stabilized according
to the condition of compact disk, and the ripple of a servo electric current is
decreased.


SL1 is carried in the loading mechanism.
The product made
from TNRC excellent in the periodic-damping property was adopted as the disk
tray, and the original swing arm drive system has realized the smooth operation.



The class AA circuitry is adopted as a lineout circuitry, and the
faithful waveform transmission which is not influenced by the load intensity is
realized.


The high-quality sound carbon film resistor which used the
non-magnetic-material cap is adopted as a resistor. Moreover, high-quality
sound-ization is attained by adopting an electrolytic capacitor and the
polypropylene capacitor for audios.


The digital optical output-terminal
is carried.


Gilding is given to the line-output termination.


The
display-device mode functionality in which a display-device window can be
switched off is carried, and function-logic-diagram window noise can be stopped.



Wireless remote control is attached.
