AIWA XK-S7000 Cassette Deck , way far form simple build , breath taken.. 25khz on Metal tape recording!
This will beat any decks ever made , even some or most reel to reel decks. This deck is serviced and working. The XK-S7000 opens up a new realm in cassette audio, with several important advances to push sound performance to the highest level possible including digital inputs cassette deck that pushes the limits of analog decks and adopts Super A / M / T / S and stress-free 6N winding pure amorphous head. Dolby S type is adopted as a noise reduction system.The Dolby S type is a noise reduction system that optimizes professional Dolby SR (spectral recording) used in recording studios for consumer cassettes, with a noise reduction effect of up to 10 dB in the low range and up to 24 dB in the high range. In addition, there is no pumping (dynamic side effect) that is common in conventional NR, and natural high-quality sound is realized. Since the Dolby S type is audibly compatible with the B type, it can be played on a cassette deck equipped with the B type. In order to completely prevent tape vibration, super A, M, T, S (Super Anti Modulation Tape Stabilizer) is installed. Super A / M / T / S is an advanced version of A / M / T / S, which is Aiwa's unique stabilized mechanism. The cassette box inherits the two-layer structure of non-magnetic aluminum plate and non-repulsive rubber, while strengthening the pressure applied to the front surface of the half body from the conventional 1 kg to 1.5 kg, and the non-repulsive rubber with different properties from the back side. Further vibration reduction is achieved by crimping with. In addition, the capstan motor, which is the vibration source inside the deck, is supported by two damping steel plates with a three-layer structure and special damping rubber, and is floating. Furthermore, the mounting of the recording head and the reproducing head is strengthened from two-point support to three-point support, and it is precisely fixed to a heavy weight head block, and a head stabilizer that dumps from both sides with non-repulsive rubber is also installed.
With these structures, a thorough vibration control mechanism has been realized to achieve even higher sound quality. The BTOR (Blank Tape Optimized Recording) system which is a recording position only for raw tapes is carried. In the conventional cassette deck, even when recording on a tape that was never used, it passed through the erase head and affected the signal system by the erase current.Sound quality is improved by improving this with BTOR. The real 18-bit linear dual D / A converter is carried and a digital source can be directly connected as it is digital. The D / A converter section has an independent dual configuration dedicated to the left and right channels, and it is a mutual independent by adopting a complete independent power supply system composed of a winding dedicated to the D / A converter, an independent rectification circuit of digital system / signal system, and an independent power supply circuit Interference is eliminated.
Moreover, the digital part is isolated by the exclusive shield case and the influence on the audio system is suppressed. In addition, it also has an ON / OFF switch that can stop all digital clocks. The stress-free 6N winding pure amorphous head is adopted as a recording-play head.
In order to pursue high sound quality, stress free-6 Nines purity 99.99997% or more of ultra-high purity copper is adopted for the head winding, ignoring cost. LC-OFC and PC-OCC were 99.99% or more copper called 4Nines, but in 6N, impurities decreased from 100ppm to 1ppm, distortion of atomic arrangement disappeared, and disorder of electron flow was suppressed. Moreover, the 12-layer laminated pure amorphous head with an extremely high magnetic flux density which has the characteristic outstanding as a magnetic head for audios is adopted as a head core. Sendust material is adopted as an erasing head. Compared with the single capstan, the dual capstan mechanism applies a constant high tape tension, and the adhesion between the tape and the head is also high.Therefore, if a normal ferrite material is used for the erasing head and the recording / reproducing head, the spontaneous magnetization action due to the coercive force of the ferrite material = Hc (0.1 to 0.15) causes high-frequency deterioration of the tape signal. By using a sendust erasing head with a very low Hc of 0.007 to 0.02, deterioration of the sound quality of the tape is prevented. The vibration damping mechanism is adopted, and in addition to the heavy-duty high-rigidity chassis and cabinet, the resonance damping wood base by the coniferous MDF board with high density is adopted in the bottom, and the external vibration is reduced. In addition, a vibration damping type with fast vibration damping characteristics is used on the printed circuit board. Furthermore, paying attention to the microvibration that the power transformer brings, we attach a large anti-vibration and magnetic power transformer externally.
In addition, we are thoroughly pursuing vibration control with heavy-weight insulators, head stabilizers, head blocks with a bias shield structure, and 3-point support high-rigidity head base. Electronic switches, switching circuits, connectors, and routing of printed patterns that cause deterioration of sound quality are eliminated as much as possible to achieve simple and straight signal transmission. In addition, the MPX circuit with a through position and the open type muting circuit at the time of performance by a gold-plated relay are equipped with a transmission mechanism that does not deteriorate the sound quality when turned off.The digital system, the mechanical logic system, the display system, the signal system, and the Dolby S NR system printed circuit board are made independent of each other, and mutual interference is eliminated by placing them at sufficient intervals. Moreover, the mechanical logic system and the display system are separated by an internal chassis to eliminate interference with the signal system, and the printed circuit board for the D / A converter is isolated by a dedicated shield case.
The manual calibration which draws out tape performance is carried. In addition, the built-in oscillator is set to 400Hz and 10kHz, allowing wide frequency characteristic adjustment. In addition, since the level meter is expanded in 0.5 dB steps during calibration, highly accurate calibration is possible.The low output impedance power source by a discrete composition is adopted. The PC-OCC low capacity head wire is adopted and it is directly attached to the reproduction equalizer. The PC-OCC winding trap coil using the low distortion core is adopted. The Dolby HX Pro circuit of the discrete composition which can be turned ON / OFF is carried.
Equipped with an ultra low distortion Dolby NR IC. The copper plating heat sink is adopted.
The low contact resistance type input / output pin jack plated with gold is adopted. It uses high-quality sound capacitors and high-precision parts.
The gilding terminal is adopted as a headphone jack. The auto-loading cassette door is adopted, and it automatically closes when the cassette is inserted. The super bias circuit is carried. It is equipped with a 3 mode display ON / OFF switch. When turned off, the clock stops.
A low distortion oscillator output that can be used for calibration of other decks and phase check of speakers is possible. Uses a quick response AI mechanism. The linear counter with a pre-end turn signal is carried. It is equipped with a large FL multi-mode display and a peak meter with 24 segment x 2ch peak hold (Auto / Manual Reset is possible). Comes with a wireless remote control.
Aiwas original AMTS (anti-modulation tape stabiliser) cuts resonance for clearer sound, while the Bias Shield Head Block works during recording to shield the playback head for the detrimental effects of recording flux. Amorphous heads are used for both recording and playback, with internal coils wound with PC-OCC copper wire for optimum conductivity.
This translates to greater audio accuracy, particularly in music with delicate passages and subtle transients. Unique only AIWA's motorized front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape loading/unloading is operated motorized and the cassette needs to be placed with the side to be played facing forward in the cassette well.Level meters used on the XK-S7000 are generic digital peak reading meters with peak hold for easy adjustment of optimum recording level. Full-logic transport controls used on the XK-S7000 let it respond to the slightest finger contact for fast and effortless transport function selection. Cue and review can be used to easily and quickly locate the beginning of a passage. To ensure the best response from the wide variety of tapes available adjustment of, bias and sensitivity, to optimum levels can be performed prior to recording. Dolby S-type noise reduction gives cleaner transient response, provides lower noise levels, both at low and high frequencies, and allows higher signal levels to be recorded safely on the XK-S7000.
Dolby S-type noise reduction provides 24 dB of high frequency noise reduction plus an additional 10 dB of low frequency noise reduction. The Dolby HX PRO system provides precise bias control during recording to reduce distortion and improve linearity in the high-frequency range, the result is recorded sound that is highly faithful to the original.
The three-head configuration of the XK-S7000 requires a Double Dolby system, one for recording and one for playback. The 19kHz multiplex pilot slgnal present in FM stereo broadcasts can cause false triggering of the noise reduction system. The switchable MPX filter of the XK-S7000 filters out the pilot signal, and assuring proper Dolby processing of FM stereo programs.
For undisturbed listening a jack connector for a pair of stereo headphones is supplied. Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
