A reference model cassette deck that pursues the ultimate in analog decks and aims for
master numbers.
The A, M, T, S (Amti Modulation Tape Stabilizer) is carried in order to reduce the vibration of
a cassette half.
In A, M, T, S, the cassette box has a two-layer structure of a non-magnetic aluminum plate and
a non-repulsive special rubber that has been carefully examined for sound quality, and the half
body is precisely and securely crimped and fixed with a pressure of about 1 kg. doing. Thereby,
the modulation noise and the tape running noise are reduced sharply.
The super stabilized tension dual capstan mechanism is carried in the mechanism part.
In this mechanism, two capstans maintain a constant tape tension from the beginning to the
end of winding. In addition, Aiwa's original micro-grain processing is used for the capstan
on the take-up side, and fine granular processing is performed on the surface of the capstan
to prevent tape slip and prevent deterioration of the tape and capstan itself. It is mitigating.
Moreover, the frequency-separated type dual-p element tongue which changed the shaft
diameter of two capstans is adopted, the overlap of frequency is eliminated, and the resonance
is prevented.
The three motor composition is adopted, one for FF / REW, one for the capstan, and one
for winding at the time of recording and rewinding, each equipped with a dedicated motor.
Furthermore, the take-up motor adopts a belt drive drive to improve the sound quality, and it is
free from the cogging that occurred in the method of educating FF / REW.
In addition, high-precision processing is applied to the zinc die-cast heavy-duty flywheel, and
each one is dynamically balanced before mounting to achieve excellent characteristics.
The heavy-weight zinc die-cast head block of 30g is adopted as a head block. Thereby, the
modulation noise is reduced by suppressing the minute head vibration. Furthermore, the bias
shield is set in the head block, and the bias leakage and the signal leakage from the sound-
recording head wire to the play head wire are suppressed.
The amorphous head which was excellent in the saturation magnetic flux density, magnetic
permeability, wear resistance, etc. is adopted as a sound-recording-play head. Furthermore,
PC-OCC with a purity of 99.997% and an oxygen content of 5ppm or less is adopted as
a winding of a head.
Furthermore, the head shape has adopted Aiwa's original design which paid attention to
the contour effect, and has suppressed the low-pass exposure.
Compared to the single capstan, the dual capstan mechanism applies a constant higher
tape tension, which improves the adhesion between the tape and the head. Therefore, if
a normal ferrite material is used for the erasing head, the spontaneous magnetization of the
ferrite material due to the coercive force = Hc (0.1 to 0.15) causes high-frequency deterioration
of the tape signal. For this reason, a sendust head with a low Hc of 0.007 to 0.02 is used for
the erase head.
As a noise reduction system, Dolby B / C type is installed in dual, and dbx is also installed.
The Dolby HX pro which improves the dynamic range and the frequency characteristic of
a high region is carried.
In Dolby HX Pro, the characteristic is improved by changing a bias amount to the optimum
state in 1/1000 second unit and recording according to a high region signal.
Moreover, by making the circuit of Dolby HX Pro a discrete composition, the optimum circuit
constant is selected one by one according to the head to be used, and the sound quality is
further improved.
The playback head and playback amplifier that use the PC-OCC winding are directly connected
by the PC-OCC wire, and the peaking capacitor that causes a phase shift in the high
frequency range is included, including the connector and coupling capacitor that cause deterioration of sound quality. It is completely eliminated.
Furthermore, the low noise, low distortion, high withstand voltage, high slew rate DC
configuration amplifier developed exclusively for the amplification element is adopted.
Combined with a high-precision equalizer element, the dynamic range is expanded and the
sound quality is improved.
The large capacity power transformer which became independent for a logic system and
a signal system is adopted as a power-source part. The digital signal of the logic system and
the analog signal of the signal system are completely separated, and the signal leakage and
the adverse effect from the digital system to the analog system are suppressed.
In addition, the transformer itself has a vibration-proof design that is hardened with an
epoxy-based filler, and by setting the transformer outside the main body, the adverse effects
of flux and micro-vibration generated by the power transformer on the tape head and signal
system are eliminated. increase.
The printed circuit boards of the mechanical logic system, the display system, and the
signal system are made independent, and the independent separation structure installed
with sufficient space is adopted.
The mechanical logic system and the display system are separated by the internal
chassis respectively, and the interference to the signal system is eliminated. Furthermore,
the recording system and the reproduction system are also completely separated, and the influence to the reproduction system from the recording system signal and the high frequency
bias at the time of recording is prevented.
By eliminating as much as possible the routing of electronic switches, changeover circuits,
connectors, and print patterns that cause sound quality deterioration, simple and straight
signal transmission is achieved.
Moreover, the transmission mechanism which does not cause the deterioration of sound quality
at the time of OFF, such as the MPX circuit with a through position and the open type
muting circuit at the time of a performance, is carried.
The bottom of the main body is equipped with an insulator with a unique structure, and the
side wood is equipped on the side to prevent resonance.
In addition, anti-vibration material is used for the top plate and bottom plate, and the
recycled board is firmly fixed with two special holders and six special screws with flanges.
The manual calibration is carried. In addition, the built-in oscillator is set to 400Hz and
10kHz, allowing for a wider range of frequency response adjustments.
In addition, the level meter is expanded to 0.5 dB steps during calibration, enabling
highly accurate calibration.
It is possible to set a three-stage recording equalizer according to the type of recording source
and tape.
High emphasizes low frequency MOL (Maximum Output Level), Norm emphasizes
standard setting, and Low emphasizes high frequency MOL.
The linear counter is carried and the pulse from the left and right reel stands can be calculated
at high speed, and both tape running can be digitally displayed in minutes and seconds. It can
be displayed in all driving modes.
At the time of sound-recording, the pre-end turn signal which blinks from 3 minutes before the
tape end (when using C-60) is carried.
The MPX filter and the bias trap filter which used the PC-OCC winding and the low distortion
core are adopted.
The peak hold with a peak hold of 24 segments x 2ch is carried.
This meter can be Auto / Manual Reset.
The detent type sound-recording volume which is excellent in separation and crosstalk characteristics, and has little left-right interlocking error and sound quality deterioration is
adopted.
The 70 micron copper foil printed circuit board is adopted.
The AC cord with polarity display using OFC material is adopted.
Gold-plated terminals are used for the input / output terminals and headphone terminals.
The metallized polyester film capacitor which reduced the auditory distortion by the
special three-layer structure is adopted.
The OFC heat sink is adopted.
Comes with a wireless remote control.
