FISHER MT-6360 (1980) - Micro Processor Controlled

turntable

The MT-6360 "programmable, full automatic, infrared remote control" turntable was introduced by Fisher in 1980. It is actually a rebranded Sanyo TP 880, Fisher being a Sanyo brand by this time. It is not really programmable, but it does have an infrared sensor next to the cartridge which can "read tracks" on the vinyl allowing you to select a track you want to listen. This can also be achieved with the use of the supplied remote control. Technically the turntable features a DC Servo Direct Drive motor, strobe light for speed adjustment and the tonearm came factory equipped with a Audio Technica MG-S100 cartridge. (Wow and Flutter is 0.035% and rumble is -70dB). The was sold both as a separate unit but also as part of various Hi-Fi system. When sold separately it was named MT-6360 and it came with it's own remote. When it was sold as part of the Fisher 9000 System it was called the MT-9000 and it was intended to be remote controlled through the CB-9000 control center of the system and its M-9000 full system remote control. Size of the unit is 440x135x385 mm, weight is 8.2 kg and it was originally sold for 798 DM in Germany.

Bang & Olufsen Beogram 8000 (1981) - Danish State-of-the-Art

turntable

In 1973, Bang & Olufsen launched the world's first record player with an electronically controlled tangential arm, the 4000 series. Beogram 8000 was the third generation of tangential arm decks. Although it shares some basic concepts with the 4000 Series, the Beogram 8000 is a completely new product. There are two parallel arms on a single carriage, one carries a light source and detector to sense the presence or absence of a record on the turntable. The other arm holds the top-ranking MMC 20CL cartridge from Bang & Olufsen. This cartridge has a sapphire cantilever and a line-contact diamond stylus that tracks at a 1-gram force. A stylus brush, mounted inside the tangential arm compartiment, keeps the diamond free from dust and microparticles, and thereby enhances the gentle treatment of your records. To secure constantly accurate rotary speed the Beogram 8000 utilizes a Tangential Drive system. It incorporates a quartz-controlled flywheel, similar to the system used in electricity meters. Like the electricity meter, the system is highly reliable and extremely accurate and there are no motor vibrations to distort the sound. A digital display keeps you informed of speed during play. Computerized control system allows one-touch automatic operation with pause and repeat functions. There is possibility for fast and slow arm scan for inner track play and there is a manual over-ride for non-standard disc speed/size and record cleaning. Technical data: Rumble>70dB DIN weighted | Wow & flutter <0.02% WRMS | Speed deviation 0.02%. Pitch control gives +/-3% speed variability | Frequency response 20-20,000Hz +/-1dB | Dimensions: 49x9x37 cm | Finishes teak/rosewood/oak/white | Weight 9kg | Original sale price 1798 DM in Germany.

ELAC 250 4Pi (1985) - German Engineering

loudspeakers

The ELAC 250-4Pi loudspeaker system was designed as a 4-way unit. Each of the loudspeaker chassis used only has to transmit the frequency range in which it works best. The playback quality is clearly audibly better because the amplitude frequency response (the evenly loud playback of all frequencies from the deepest bass to the highest treble), the phase behavior and the directional characterteristics are optimal. The - compared to conventional three-way systems - smaller frequency band, which is transmitted by the speaker chassis, eliminates the otherwise frequently heard sound discoloration in the mid-range, for example, and the sound radiation is more even, less directed.

The low frequencies are transmitted up to around 550 Hz by four small special low-frequency drivers. The comparatively small cones are lighter and more stable than those with a larger diameter. The lower dead weight and the powerful coating due to the four large magnets result in an optimal power/mass ratio. Great acceleration is essential for the realistic bass reproduction and therefore no problem. The unintentionally precise impulse reproduction has an overwhelming effect. A total of four loudspeaker chassis - all special developments for the 250-4Pi - work in parallel, falling through the transmission line. The bass systems and the transmission line were designed in such a way that the lowest frequencies down to 20 Hz can still be reproduced cleanly.

The midrange, which is so important for the natural sound image, is transmitted by two fabric dome speakers. Frequencies from 550 to 1450 Hz are reproduced by the 80(!) mm dome system. It can transmit this frequency range precisely and without distortion. The MT 25 high-midrange system, a special ELAC development, transmits the frequency range between 1450 and 4000 Hz.

For the reproduction of the high tones from 4000 Hz, the 4Pi uses a technology newly developed by ELAC engineers and patented together with the Dutch group Bakker/van den Hul is used for the first time. Instead of the usual dome or cone diaphragms, a cylindrical aluminum strip that is only 5 thousandths of a millimeter (5 μm) thin is used. This extremely light cone has unmistakable advantages: an exceptional impulse reproduction is achieved thanks to the low surface weight. Only sound-radiating parts are moved in this innovative tweeter system. There are no longer any drive coils, which ignite the oscillating mass in conventional tweeter systems and thus round off the finest impulses during playback. Two powerful toroidal magnets arranged above and below the cylindrical ribbon holder generate the force field to move the aluminum ribbon. With the ELAC 4Pi technology, high frequencies are emitted evenly in the room, a basic requirement for homogeneous sound propagation in the listening room.

High quality crossover network. The 250-4Pi contains only selected components. The high-quality air coils are manufactured by ELAC itself - only then can the exact optimum values ​​be maintained within the narrow tolerances specified for this high-quality speaker system. Only film capacitors are used so that the first-class sound impression is retained for years to come. They guarantee long-term stability of their physical parameters. Even the influence of the connection cables on the sound was taken into account: oxygen-free copper cables connect the chassis to the network, the network to the connection terminal.

Technical data: 4-way Transmission Line | Dimensions: 1550x460x460mm | Weight:90kg | Crossover frequencies: 560/1450/4000Hz | Power: 350/250W (impulse/nominal) | Frequency range: 18-28000Hz| Sensitivity: 83 dB/1W/1m | Minimal impedance: 2.3ohm | Original sale price: 2x7498 DM, Germany.
