The turntable scheme compact disk player which
carries legato linking conversion.
The legato linking conversion system
developed aiming at the more natural music play is carried.
circuitry, between the music signal datas currently recorded on the disk is
connected with the smooth function curve suitable for reproducing the sound of a
nature, and the frequency component of a musical instrument, and the play of the
original sound signal with few ringings (wave-like disorder) is enabled.
presuming the music signal at the time of the sound recording before being
recorded based on the signal currently recorded on compact disk, according to
the 1/f damping characteristics, reappearance with a sound of 20kHz or more was
also attained, and natural sound is realized.
The turntable scheme is
adopted as a mechanism part.
This is a scheme which reads a signal in the
disk which installs upwards the pickup and spindle motor which were under the
disk, and rotates on a turntable 12cm in diameter,Adoption of a spindle motor
with moment of inertia with a big turntable which supports a disk the whole
surface from the bottom, and generous starting torque etc. has realized the
stable rotation performance strong also against a load variation.
high speed pulse flow 1 bitD/A converter which Pioneer developed uniquely is
carried in the digital analog converter by the right-and-left independency.
A 1-bit scheme is that zero cross distortion and a glitch noise have the distinctive characteristics of not generating theoretically, and moreover operate noise shaping on 384fs and a very high oversampling frequency,A smooth output is attained and the noise floor by re-quatization is reduced greatly. For this reason, since the sub- noise shaper of a low degree can be used, the influence of the noise of an out-of-band is suppressed low.
Furthermore, the influence
by Jitter occurrence is also decreased by operating a master clock with a clock
frequency as low as 16.93MHz.
The direct construction was adopted, the
center tray design was adopted, and the pickup mechanism is arranged in the
center of a chassis. Furthermore, main circuitries were arranged along with the
fluence of a signal, and from a pickup to the output-terminal is tied so that it
may become the shortest distance.
This is reducing the influence of an
The twin power transformer which made it become
independent digital one/object for servo circuitries, and for analog circuits,
respectively is carried in the power-source part.
Moreover, the stable
powering is realized by the power circuit's having employed 3 part 7 regulator,
having carried out the independent rectification of the three parts of a
servo/digital one, a digital analog converter, and an audio, and having
eliminated the cross interferencee.
The honeycomb chassis excellent in
rigidity is adopted as a chassis, and the high vibration suppression effect is
demonstrated. Furthermore, in order to suppress a reflection of the sound from
the outside, the insulator has also adopted honeycomb structure.
being alike -- it equips with a resin stabilizer and the vibration proof of the
chassis is improved.
Functionalities, such as a compu-program edit, a
time fade edit, an auto special-NetWare-program edit, are carried.
peek search, the memory hold, the display-deviceoff switchpoint, and the digital
one / analog circuit changing switch are carried.
The compact disk-DECK
synchro termination is carried.
