The compact disk player which adopted newly
developed 4DACs and 18-bit conversion system.
4DACs and 18-bit
conversion system are adopted as a D-A-conversion part.
In this circuitry, Lch, two Rch each, and a total of four D/A converters
are adopted,While banishing zero cross distortion theoretically by carrying
out the unity coupling of the digital analog converter for exclusive use
by newly developed 4DAC processor LSI by the negative Masanobu number of
both channel, and signal side, respectively, an 18-bit high-resolution
operation is realized. Thereby, the reappearance capacity of a minute signal
is raised sharply.
Moreover, the 266th 18-bit
high-order-accuracy oversampling digital filter is adopted as the digital filter
which removes an unnecessary RF component 4 times, and the high fidelity play is
enabled by decomposing signal level into 18 bits from the conventional 16-bit.
classAA which is a high-quality sound circuitry technology original with
a lineout circuitry and a headphone circuitry is adopted. This has realized the
faithful waveform transmission also to a complicated connected load, and the
super-low distortion and the high-resolution are realized.
speed linear-access system which used the linear motor is adopted as the actuator of the traversal mechanism to which a pickup is moved. The rapid access
is realized by applying a polish to the original control system which made full
use of a microcomputer, and a high endurance and silence are realized at the
same time it raises an operationality.
Moreover, the pickup has acquired the
signal read capacity to really have excelled by adoption of the molding glass
lens, and a high robustness.
By adopting the multilayer structure base
which consists of a heterogeneous metals, and a multilayer structure top plate,
the reduction of the oscillation which has an ill effect on a tone quality is
Moreover, to the floor oscillation directly transmitted from a
setting stand, the reduction is aimed at by adopting the multiplex insulator
stream composition by the double floating of four large-sized insulators and
Two digital outputs, light and a coaxial, are carried.
Moreover, the digital output ON/OFF switchpoint which can intercept the
influence of a digital output at the time of an analog play is carried.
The independent 2 coil power transformer with which the audio system and
the digital-servo system became independent is adopted as a power circuit, and
it has prevented the influence of the intense digital circuit of a variation or
a servo circuitry attaining to an audio system.
Moreover, the powering
stabilized by adoption of the low-noise active servo power supply is realized.
The edit guide functionality is carried, and only by choosing the enrolment time (90 minutes/60 minutes/46 minutes) to a tapes, the number of music, the sequence of music, and sound-recording time which can be recorded on a tapes A side / B side are calculated automatically, and it can display on a display device.
After carrying the digital peek search and carrying out the autmatic
detection of the peak level of disk all songs or special-NetWare-program music, a part and a total of 6 seconds are repeated for peak-point order }3 seconds, and it can perform. The optimal recording level by the side of the deck can be
easily set up by using this functionality.
