It uses Dolby S-type noise reduction system.The Dolby S-type is a noise reduction system optimised for consumer cassettes from the professional Dolby SR (Spectral Recording) system used in recording studios, and achieves noise reduction of up to 10 dB in the low frequency range and 24 dB in the high frequency range. It also eliminates the pumping (dynamic side-effects) common to conventional NR, resulting in natural, high quality sound.The Dolby S-type is audibly compatible with the B-type, so it can be played on cassette decks equipped with the B-type. Super A-M-T-S (Super Anti Modulation Tape Stabilizer) prevents tape vibration.Super A-M-T-S is a development of Aiwas original stabilising mechanism, A-M-T-S. The cassette box inherits the two-layer structure of non-magnetic aluminium plates and non-resilient rubber, while the pressure applied to the surface of the half body is strengthened from 1kg to 1.5kg, and is also pressed from the back side with non-resilient rubber of different properties to achieve further vibration reduction.The capstan motor, which is the source of vibration inside the deck, is supported by two three-layer vibration-damping steel plates and special vibration-damping rubber to keep it floating. Furthermore, the recording and playback heads have been reinforced from two-point to three-point support, and are precisely fixed to the heavyweight head block, which is also fitted with a head stabiliser that is dumped from both sides using non-rebounding rubber.These structures provide a thorough vibration-damping mechanism for even higher sound quality. The BTOR (Blank Tape Optimised Recording) system is a recording position dedicated to raw tape.In conventional cassette decks, when recording to a tape that has never been used, it still passes through the erase head, affecting the signal system due to the erase current. This is improved by BTOR to improve sound quality. Real 18-bit linear dual D/A converters allow direct connection from digital sources in digital form.The D/A converter section has an independent dual configuration for left and right channels, and uses a completely independent power supply system consisting of a dedicated D/A converter winding, independent rectification circuits for digital and signal systems and independent power supply circuits to eliminate mutual interference.In addition, the digital section is isolated by a dedicated shield case to minimise the effect on the audio system. In addition, an ON/OFF switch is provided to stop all digital system clocks. The recording and playback heads use stress-free 6N-wound pure amorphous heads.In pursuit of high sound quality, ultra-high purity copper with Stress free-6Nines purity of 99.99997% or higher is used for the head windings without regard to cost; LC-OFC and PC-OCC had 99.99% or higher copper, called 4Nines, but with 6N, impurities are reduced from 100ppm to 1ppm The distortion of the atomic arrangement has been reduced to 1 ppm, disappearing and reducing the turbulence in the flow of electrons.The head core uses a 12-layer laminated pure amorphous head with extremely high magnetic flux density, which has excellent characteristics as an audio magnetic head. The erase head is made of sendust material.The dual capstan mechanism applies a higher and more constant tape tension than a single capstan and provides a higher degree of adhesion between tape and head. For this reason, using normal ferrite material for the erase and record heads causes high-frequency degradation of the tape signal due to the spontaneous magnetisation effect caused by the coercive force = Hc (0.1-0.15) of the ferrite material.The use of sendust erase heads with an extremely low Hc of 0.007-0.02 prevents deterioration of the tapes sound quality. The mechanism uses a four-motor closed-loop dual capstan mechanism.The left and right capstan drive, dedicated FF/REW and recording/playback motors are independent, and a belt-driven low cogging mechanism was developed based on the concept of an analogue thread drive player. Another motor is used for Super A, M, T, S and cassette box drive.The capstan uses Aiwas unique micro-grained frequency-dispersive capstan, which causes less tape damage, and together with the high-precision flywheel, each of which is precisely and dynamically balanced, achieves a wow-flutter figure of 0.018%. A vibration-damping mechanism is employed, with a heavy, highly rigid chassis and cabinet, and a resonance-damping wood base with high-density softwood MDF board on the bottom to reduce external vibrations. In addition, a vibration-damping type printed circuit board with fast vibration damping characteristics is used.Furthermore, attention has been paid to the micro-vibrations caused by the power transformer, and a large anti-vibration, anti-magnetic type power transformer has been externally mounted.In addition, vibration damping is thoroughly pursued through the use of heavyweight insulators, head stabilisers, a head block with a bias shield structure and a three-point support high-rigidity head base. Electronic switches, switching circuits, connectors and printed patterns that cause sound quality degradation have been eliminated as far as possible to ensure simple and straight signal transmission.The transmission mechanism is also equipped with an MPX circuit with a through-position and an open-type muting circuit with a gold-plated relay during performance, which prevents sound quality degradation when the unit is switched off. The printed circuit boards for the digital, mechanical logic, display, signal and Dolby S NR systems are independent of each other and placed at sufficient intervals to eliminate mutual interference.In addition, the mechanical logic and display systems are separated by an internal chassis to eliminate interference with the signal system, and the D/A converter printed circuit board is isolated by a special shield case. Manual calibration is provided to bring out the best tape performance. In addition, the built-in oscillator is set to 400 Hz and 10 kHz for wide frequency response adjustment.In addition, the level meter is expanded in 0.5 dB steps during calibration, allowing highly accurate calibration. Three recording equalisers can be set to suit the recording source and tape.High is a setting that emphasises low-frequency MOL (Maximum Output Leve), Norm is a standard setting and Low is a setting that emphasises high-frequency MOL. Low output impedance power supply with discrete configuration. PC-OCC low capacitance headwires are used and are directly attached to the playback equaliser. PC-OCC wound trap coils with low distortion cores are used. It has a discrete Dolby HX Pro circuit with on/off capability. The system is equipped with an ultra-low distortion Dolby NR IC. The system is equipped with a high-precision detent-type recording volume. 70 micron thick copper foil printed circuit board. Special triple-layer large metallised polyester film capacitors are used. OFC extra-thick power cord with polarity indication is used. OFC heat sinks and copper-plated heat sinks are used. Gold-plated low contact resistance input/output pin jacks are used. High sound quality capacitors and high-precision parts are used. Gold-plated terminals are used for the headphone jack. Three nitrogen gas-filled gold-plated relays are used. An autoloading cassette door is used, which closes automatically when a cassette is inserted. A super bias circuit is used. Equipped with a low-noise microphone amplifier with gain switching. It has a 3-mode display ON/OFF switch; when OFF, the clock stops. A low-distortion oscillator output is available for calibration of other decks and speaker phase checks. Quick response AI mechanism. It has a linear counter with pre-endo indicator. It has a large FL multi-mode display and a peak meter with 24-segment x 2-channel peak hold (Auto/Manual Reset available). It has heavyweight sidewoods with UV coating.Shipping FedEx?or DHLInternational Buyers - Please Note:Import duties, taxes, and charges are not included in the item price or shipping cost.
