|The compact disk player which carries virtual
battery operation and the S-advanced MASH class A DAC.
MASH class A DAC is carried in the digital analog converter.
consists of 3LSI which used S-advanced MASH and two PWM output ICs, and builds
the 4th noise shaping circuitry and the digital demphasis circuitry in the
conventional advanced MASH in the MASH section.
moreover, by having 3 chip
stream compositions of LSI, the separation of the PWM output IC of MASH section
LSI and each L/R channel was carried out, the influence of a digital noise was
avoided, and the crosstalk between channels is improved.
Furthermore, it is having adopted Class A DAC as a D-A-conversion part,
and changing the PWM output unit into Bipolar from conventional C-MOS,The
occurrence of the penetration electric current by the abrupt change of
the electric current in the changing point of pulse shape was reduced,
and the occurrence of overshooting on a PWM wave or a under shoot is controlled.
By this, the peak value of the pulse was stabilized and the ideal PWM wave
Furthermore, the clock Jitter
is reduced by arranging a crystal oscillator near the digital analog converter.
In order to prevent the wraparound of the noise from a power source or a digital circuit, the virtual battery operation power circuit is carried.
In this circuitry, during a music play, only the voltage charged by the
capacitor is made into criteria potential, it is a thing of FET to do for gate
control, and the noise from a power source is intercepted. This has prevented
that a noise is mixed with a sound signal.
In order to reduce the ill
effect by oscillation, THCB (technics hybrid construction base) is adopted, and
the periodic-damping property which was excellent with an effective combination
of a steel plate and a viscoelasticity object is acquired. Furthermore, the
oscillation from a floor is intercepted by four insulators.
optical deck mechanism is arranged in the good central part of a weight balance, and the oscillation of a mechanism is controlled.
The bamboo fiber ¬´
separator is adopted as an electrolytic capacitor, and the play which stopped an
unnecessary incidental sound is enabled.
The digital servo is adopted as
a servo circuitry, by adjusting the amount of servoes according to a different
condition for every disk, the stable drive is enabled and the improvement in a
tone quality is aimed at.
The weight balance and the center mechanism
with a sufficient stability are employed as a disk tray.
optical termination is carried.
The line-output termination in which
gilding was given is adopted.
The peek search function is carried.
A music carries out the autmatic detection of the location which
actually starts, and stands by for it, and the Autocue functionality which can
be started in an instant is carried.
The A-B repeat in which the repeat
performance of arbitrary zones is possible is carried. .
The length of
the tapes to record is carried out, it volunteers, and compact-disk
sound-recording edit function in which the edit without a sound piece is
possible is carried. .
An Output-voltage coordination is possible per
2dB from 0dB to -12dB. .
Time fade and a random play functionality are
