The compact disk player which concentrated
compact-disk developer's technology, and the essence of the know-how, and
realized high completeness.
In a D-A-conversion circuitry, the Philips
Marantz develops uniquely, and is constituted from original LSI (TDA-1541A S-1)
to which the enhancement was come in piles.
This TDA-1541A S-1 is the selected type further selected carefully out
of Philips's newest device A version, and the crown multiple asynchronously
communicating hosts is stamped with the model number.
This has usually guaranteed 1least significant bit on level 0.5
least significant bits covering total-temperature width at the time of a very
The stream composition of a D-A conversion carries two
digital analog converters per channel, and, moreover, has adopted the push pull
Two converters serve as combination of a right phase and negative phase, and a wave is compounded through here. An inphase component
is canceled, an eventh included low distortion is also offset by it and the
concurrent, and they reduce the hum and the super-low-pass noise sharply.
In order to employ the performance of single compact disk in the maximum
efficiently, the sensor detected 12cmCD and 8cmCD and the span of a servo
operation was switched by the circuit constant, and it has set up so that the
operating point may turn into the middle point.
The drive mechanism has
adopted CDM-1 type which the Philips Marantz developed.
It is a swing arm pickup of 1 beam scheme borne by the way of thinking
different from the usual linear-tracking. The lens is an RODENSTOCK glass,
and aberration is excellent in the temperature characteristic few, and
it is raising pickup capacity.
Moreover, the samarium cobalt magnet was adopted as the
linear motor used as the source of power, and the servo system which controls a
swing arm, the conjointly smooth and positive bit, and the race are realized.
Moreover, the die-casting base is adopted for a rigid improvement, and the
influence of an extraneous vibration etc. is suppressed.
composition called the large-sized transformer which is equal to power
amplifier, and the electrolytic capacitor of 68,000 micro Fx2 is adopted as a
power-source part. New materials were adopted especially as the electrolytic
capacitor, and the tone-quality serious consideration type is selected carefully
and adopted as it.
Moreover, the power transformer divided the secondary
winding into the object for digital circuits, the object for audio circuitries, and display-device circuitries, and has achieved independent-ization.
noise which a regulator circuitry also adopts a discrete stream composition and
is related to a power-source part is eliminated.
The product made from
die-casting is adopted as a chassis, and also the oscillation is suppressed by
considering it as the firm sandwich construction which consists of a sole plate
of the side panel made from die-casting, and 3mm thickness.
ARC (Aluminium Faft Ceiling) structure original with a Marantz is adopted as a
top cover, and strength improvement and an oscillation mode diffusion are aimed
at by considering it as 3 piece structures where the Raft (raft) cut was
Furthermore, it is isolated from a rotation system and the
preamplifier for laser signals usually mounted in a mechanism is suppressing the
influence of an oscillation.
In order to prevent a harmful cross
interferencee with vibration proof, paying attention to the circuit layout, a
digital circuit, the audio circuitry, the servo circuitry, the microcomputer, and the display-device circuitry are considered as the substrate stream
composition which became independent, respectively.
Two digital outputs
of a coaxial are equipped as it is optical.
If filing bank"FTS" other
than the usual random access special NetWare program (20 music) is carried and
memory of the special NetWare program is carried out once, even if it turns off
the power, it can file semipermanently.
