The compact disk player which carries high-quality
sound technologies, such as S-advanced MASH and Class A DAC, and virtual battery

S-advanced MASH and Class A DAC are adopted as a
D-A-conversion part.
This circuitry is considered as S-advanced MASH and
3LSI stream compositions of two class A PWM output ICs which were adopted from
the high order model, and upgrade is aimed at by building a 4th noise shaping
circuitry and a digital demphasis circuitry in the conventional advanced MASH.
moreover, by 3 chip-ization of LSI, the separation of the PWM output IC of MASH
section LSI and each L/R channel is carried out, the influence of a digital
noise is avoided, and the stroke between channels is reduced.

Moreover, the PWM output unit was changed into Bipolar from conventional
C-MOS, and the occurrence of overshooting on a PWM wave or a under shoot
is controlled by reducing an occurrence of the penetration electric current
by the abrupt change of the electric current in the changing point of pulse
shape. The peak value of the pulse by this was stabilized and the ideal
PWM output is realized.
Furthermore, the clock Jitter is stopped by arranging a crystal oscillator
near the digital analog converter.

The virtual battery operation
circuitry is adopted as a power-source part.
In this circuitry, the FET
element was included in the power circuit, it is a capacitor charge side, the
noise of an AC power source and the noise mixed in an audio circuitry from a
reference-supply occurrence were intercepted, and it has prevented a noise
mixing in a sound signal.

The digital servo was carried and the stable drive is realized by adjusting
the amount of servoes according to the status of each one one-sheet disk.

While having adopted the silence
mechanism and making a disk tray wide with 140мм, the mechanism is arranged in
the good center of a weight balance. Moreover, TNRC by the multilayer structure
of a metals and BMC is adopted, and the oscillation from the outside is reduced.

SL1 excellent in silence is adopted as a loading mechanism, and the clearness
of a sound is secured by suppressing a mechanism's vibration. Furthermore,
the silence operation is realized by adopting an original swing arm drive

The class AA circuitry is adopted as a lineout circuitry,
and the ideal Class-A operation is realized.

The internal and external
oscillation is reduced by THCB (technics hybrid construction base) which
acquired the periodic-damping property excellent in combining a steel plate and
a viscoelasticity object, and four large-sized insulators.
Moreover, the
oscillation of a mechanism is controlled by arranging an optical deck mechanism
in the good central part of a weight balance, and also carrying out a floating
by a double insulator.

The digital optical termination is carried.

The display mode functionality is carried and a display-device window
can be switched off.

The line-output termination in which gilding was
given is carried.

The synchro edit functionality is carried, by
combining with the cassette deck with an exclusive termination of
technics/Panasonic, the deck is interlocked with and an edit sound recording can
be performed.

The peek search function is carried.

remote control is attached.
