CD player developed aiming at the ideal of CD player which an Akai considers.
Vibration suppression-ization of the main part of a player is thought as important, and the anti Resonance construction is developed and carried.
compounded type laminated-damping-steel-sheets anti Resonance new metal which
sandwiched the polymer material original with a cabinet arm top cover with the
metal sheet steel is adopted. This sheet steel does not vibrate easily compared
with an ordinary griddle, and the damping characteristic is also very short.
Moreover, the new-materials anti Resonance special rubber excellent in the
oscillating damping characteristic is adopted as an insulator, and external
vibration is absorbed.
Furthermore, rubber and a spring were combined and
the double insulated floating mechanism which insulates mechanically the whole
Mechanism Block including an optical system/drive system from a main part is
adopted,Vibration of comparatively high frequency is absorbed by a spring, and
the oscillating ingredient of low frequency is absorbed with special rubber.
Strengthened the power-source part, a digital system and analog system
including a servo circuit were made to become independent of the winding
wire of a power transformer, and the separate power supply which also separated
the rectifier circuit completely is adopted. Moreover, the rectifier circuit
of an analog system has the composition of having made the object for amplifier,
and the object for D/A converters becoming independent further. Thereby,
the shake of the power source from a digital circuit and mixing of detrimental
constituents, such as a noise, are eliminated.
Moreover, since the allowance of a power-source part is related to massive
[ of a low-pitched sound region ] etc., it has adopted two 2,200-micro
F electrolytic condensers of special edition as the current supply circuit
of each digital one / analog at a time,Resonance is dumped, a paint also
carries out what is not mixing a metal ingredient, has it, and nonmagnetic-ization
the reading mistake by the blemish or dust is likely to be prevented applying a
usually comparatively light servo and a trace mistake is likely to occur in a
sudden external vibration, the servo control system of a new method which
strengthens a servo is adopted as a servo circuit.
Traceability is improved
greatly by this and a large change of the amount of servos is suppressed.
The digital filter with the amount of attenuation of 90dB is developed
and carried, and a sharp damping characteristic and delay characteristics [
almost flat in an audio zone ] have been acquired.
After the digital filter,
the 7th low distortion low pass filter was inserted, and the remains ingredient
is removed in the loose curve. The Copper-foil styrene capacitor by which the
result of having excelled in few coils (high core type) and listening
comprehension tests which cry was obtained was adopted as this filter, and sound
quality degradation is prevented.
In addition, parts, such as a Copper-foil
styrene capacitor, metal tunic resistance, a high-speed Bi-FET operational
amplifier, are thrown into the key point of analog circuitry including a
The It's Logic function which is a programming
mechanism original with an Akai is carried.
This is original with the Akai
which constructs a program combining a ten key and three keys called And, To, and Without, and when performing even the 6th music from the 1st music, for
example except the 4th music of a disc, it presses 1 To 6 Without 4 and a key.
This program makes one key operation a step, and the programming of a
maximum of 27 steps is possible for it.
Functions, such as a music
search, an index search, a manual search of 2way speed, a section (A<=>B)
repeat, and a program skip play, are carried.
