SONY TC-K555ESII
¥99,800 (released in 1984)
explanation
A reference deck that further refines the TC-K555ES for perfect recording and playback of
digital sources.
The head uses a laser amorphous head that uses an amorphous alloy that does not have
a crystal structure as the core material.
TC-K555ESIINow, by enlarged the crystals of first-class oxygen-free copper (purity 99.995%
or more) in the windings of this laser amorphous head, the number of crystal boundaries is
reduced, and the distortion of the signal due to capacitance and reactance is reduced.
Crystal-Oxygen Free Copper), which enables denser recording and playback, taking advantage
of the quality of digital sources.
In addition, an independent suspension three-head system is adopted, and although
the recording head and playback head are structurally independent, the occupied space is
the same as that of the combination head, and a uniform head touch can be obtained, and
azimuth accuracy can be driven in the manufacturing process.
The driving mechanism uses a closed-loop dual-capstan system that has been proven in
open-reel decks.
It consists of two pairs of capstans and pinch rollers centered on the head tape This method
cuts off the tape vibration transmitted from the reel and improves the wow and flutter
characteristics. In addition, modulation noise can be expelled out of the audible band
by separating the span of tape vibration into short parts, and the tape tension between the
two capstans is used to obtain a stable head touch, achieving high running accuracy.
The complex transmission mechanism between the motor and the capstan has been
eliminated, and a direct drive system is adopted in which the rotating axis of the linear
BSLD.D. motor, which has a simple structure with the removal of brushes and the brushes,
is used as a capstan.
In addition, it is servo with quartz locks to reduce wow and flutter.
The amplifier section is thoroughly based on the simple and straightforward concept, and
the recording and playback amplifiers are all L/R twin mono to cut off mutual interference.
It uses a DC amplifier configuration that suppresses front-to-back and back-to-back interference
by constructing along the signal flow.
In addition, the amplifier section is combined on a single OFC board, which greatly reduces
the routing of wiring materials, and LC-OFC wires are used as wiring materials, making the
design with an emphasis on sound quality.
The ICs that make up the Dolby NR B/C circuit use a newly developed symmetry process
Dolby IC.
This IC is designed with a symmetrical L/R shape, including the amplifier circuit, and the
wiring pattern of the peripheral parts is also symmetrical, thereby reducing the difference
in characteristics between channels and improving localization.
It is equipped with a ±20% variable bias volume in three positions: Type 1 (Normal),
Type II (CrO 2), and Type III (Fe-Cr). It is equipped with a linear electronic yes that digitally displays the amount of tape travel in minutes and seconds.
In addition, it is equipped with a subtraction function that allows you to read the remaining
tape level directly.
It is equipped with a peak program meter that can display a wide range of -40dB~+8dB with an
FL tube.
It uses a double indication method that simultaneously displays the peak value of each
moment and the peak hold of about 2.4 seconds.
Functions such as yes linked memory stop/play, Rec Mute with autospace, MPX filter switch,
etc.
It adopts a gold-plated input/output jack.
The remote control unit, sold separately, allows remote control of wired, wireless, foot
remote control, etc.
In addition, continuous answering recording and alarm playback by Thailand Mar
(sold separately) are possible.
By using the optional RM-65, it is possible to synchronize the start/stop Thailand with the
Sony player.
