The compact disk player which supplied the
technology acquired by compact-disk-830DS and was developed.
carrying 16fs T.F.C. (Transversal Filtering Circuit) and carrying out the
upshift of the sampling frequency to 705.6kHz, 16 times, by a high precision
digital operation,The digital noise was shifted to the super-high region, and
the smooth wave has been obtained.
Thereby, the latter analog filter became a passive type of the simple sub- compared with the former, and has realized the
extensive modification of an expansion of a passband, element distortion, and
The 4DAC B.S.S. (Balanced Summing System) balance
type-conversion circuitry is adopted as a D-A-conversion part.
of balance type-conversion circuitries in which each two Lch-Rch uses the
digital analog converter specially chosen in the precision at the time of small
level out of DAC chosen by the merit of the linearity. The dynamic range on
Hearing impression is expanded by this, and an exact representation and the
silent clear feeling of a pianissimo are raised.
Moreover, simple-ization of
the signal path of an analog part, such as making a coupling capacitor
unnecessary, is realized by carrying out the balance operation of the method DAC
of an unipolar.
Adopted the large-sized transformer and the OFC power
cord as the power circuit, and the outstanding regulation was obtained, and also
the digital system and the analog system were separated and noise mixing is
prevented with constituting a filter by a good capacitor.
The base with picking of the mechanism of a chassis consists of materials
which were excellent in rigid high & vibration-proof property. Moreover,
the sole plate of the dual structure which added the 1.6-mm-thick griddle
to the sole plate with a usual thickness of 1mm is adopted, and the oscillation
from the interior and the visitor oscillation are reduced.
Moreover, the sintered alloy foot
(phi63.5mm) is adopted as an insulator, and an interview place and a
three-position shorted to ground are possible.
Furthermore, the key point
has a structure dumped by special vibration proof material.
