The 7000 system was essentially the same and rebadged at a later dateBeoGram CD7000 Compact Disc PlayerLarge photoManufactured: 1992 - 1995Designer: Jacob JensenColours: Silver, Black, White Beogram CD 7000 was distinctive because of its authentic sound reproduction as well as its large dynamic range. It was equally suitable for symphonic music and rock. Its many functions allowed you to pre-programme tracks for playback in any desired order. This CD player was the last in line as far as separates were concerned, replaced with the likes of Beocenter 2300 and Beocenter 2500. Features:Exclusive computer-controlled CD loading mechanism with extremely fast access time CD tray machined from a 4mm solid aluminium plate for maximum mechanical stability and convenient loading Disc tray cut-outs with rubber lining for 12 and 8cm discs Spring-suspended CD mechanism and magnetic disc clamp Special functions, such as scan and sequence programming, were carried out from Beolink 7000 Dynamic readout on Beolink 7000 of all functions, track bar, remaining time, elapsed time, scan, etc. CD players are now among the simplest constructions in the electronic world and standard players are based on very few components, a simple electronic layout and use of economical materials, both inside the product and in the cabinet. In the construction of CD7000 the main objectives were the achievement of excellent mechanical stability, convincing sonic qualities and easy access to the CD functions. The loading mechanism, the way the clamp function and the suspension of the CD mechanism were all points that received special attention. The high quality of the mechanical solutions was continued in the electronic circuitry and both were highly integrated and interdependent of each other. The CD tray was very solid and elegant and the loading mechanism extremely durable. The tray was made from a 4mm thick sheet of aluminium and the conical recess for the CD was milled and diamond polished to the smallest of tolerances - to prevent dust gathering in the recess. The circular rubber profile protected the disc during loading and unloading, while the triangular cut-out facilitated unloading. To avoid static build-up the tray was connected to ground and to avoid ringing, a damping plate was placed at the innermost part of the tray, inside the cabinet. The motorised movement of the CD tray was very fast and gentle. The movement was controlled by the microcomputer via an optocoupler and was a very stable mechanical solution with two parallel chrome plated brass rail tubes and precision plastic roller bearings. A nylon coated steel cord wire was applied for maximum duration and quiet transport. The electronically governed transport was very smooth, started the movement slowly, then speeded up very quickly, decelerating when the disc approached the clamp. Furthermore, it secured against possible damage occurring from obstacles either in front of the tray or in between tray and cabinet. While the tray approached the clamp the disc was gently lifted off the tray and clamped between the CD mechanism and magnet. The magnet was placed on a bridge across the CD mechanism and when it engaged the disc the magnet was lifted away from the bridge. While the disc was rotating, the magnet was not in contact with the cabinet, but only the disc and CD mechanism. This assembly was insulated very efficiently from the cabinet to prevent vibrations from the outside. A special suspension was designed, with 4 steel springs, encased in rubber. The springs ensured that the CD mechanism was fixed in the horizontal plane (i.e. across the disc), while a certain amount of movement was allowed in the vertical plane (i.e. up and down). Test showed that the servo system counteracts movements in the vertical plane better than in the horizontal plane, and the suspension thus was a good compromise with regard to immunity from external vibrations. The inherent frequency of the suspension was placed at 25 Hz to avoid tracking and focusing errors, which were prone to emerge if the CD mechanism was subjected to vibrations around 100 Hz and upward. Furthermore, at this frequency interference with the inherent frequency of the CD cabinet was also avoided. The electronicsThe CD format is one of the most precisely defined audio formats, but it is still possible to design differentiated products. The electronic solutions in CD 7000 were just as elaborate, the computer controlled loading just being one of the elements. Separate power supplies were available for the digital and analogue parts, and in connection with a careful print layout Bang & Olufsen achieved the most respectable electronic specifications. The digital-to-analogue filtering was special as well. First, a standard digital filtering (4 x oversampling) was applied to filter away the sidebands below 176,4 kHz. The analogue filtering at 176,4 kHz was carried out by a modified order filter. To avoid remnants of the 176,4kHz sideband having an effect on the filtering, a special suction circuit cut off the frequencies above 156,4 kHz. The modified filter was known as a Bessel elliptical filter. It had a very gentle filter characteristic and was not susceptible to ripple phenomena, phase distortion or ageing. The functionsAs with the other sources, operation was via the Beolink 7000, with full display readout of all functions. Special functions available included: the space function, where a pause of 4 seconds was added between tracks to facilitate track search on a tape recorded from CD 7000. Scan gave playback of the first 15 seconds of each track and was especially useful in connection with a sequence programming. While you were scanning the CD, tracks could either be selected (compiled) or omitted and when the last track had been scanned, playback of the programmed sequence commenced. Sequence programming could also be carried out independently of the scan function and if you used the select programming, playback could be non-chronological. If you used the reject programming to leave out specific tracks, playback would be chronological. Beogram 7000 could, ideally, be used as part of Beosystem 7000 BeoGram CD7000 Compact Disc Player Product SpecificationsTypes:5151 ( 1992 - May 1995)AUS 5155 ( 1992 - May 1985)GB 5152 ( 1992 - May 1995)J 5154 ( 1992 - May 1995)USA 5153 ( 1992 - May 1995)Frequency range: 3 - 20,000 Hz +/- 0.3 dBSignal-to-noise ratio: > 100 dB / 110 dB A-weightedDynamic range: > 96 dBHarmonic distortion incl. noise: < 0.0025% at 0 dB;< 0.025% at -20 dBChannel separation: > 101 dBChannel difference: < 0.08 dB Converter system: 2 x 16 bit, 4 x oversampling 176.4Low pass filter: Digital + Bessel/elliptical analogueDamping: > 20,000 Hz > 50 dBPhase error between L and R 0 degree at 20 - 20,000 HzOutput analogue: 1.3 V RMS at 0 dBOutput, signal: For digital equipment Power supply:5151 EU 220 V5155 AUS 240 V5152 GB 240 V5154 J 100 V5153 USA 120 VPower consumption: 23 WDimensions W x H x D: 42 x 7.5 x 32.5 cmWeight: 6.3 kg Link compatibility: Datalink Most recent S/W 1.2

Alles einwandfrei. Auch der CD-Player läuft einwandfrei. Beide Geräte sind gebraucht, aber wohnzimmertauglich. Soll heißen: keine Ecken abgestoßen, Chromleisten sauber, Beschriftung klar. Die empfindlichen schwarzen Lackflächen auf der Oberseite haben teilweise kleine Kratzspuren, die mit bloßem Auge kaum sichtbar sind - unter einer Lupe schon. Dazu gibt es noch eine: BeoLink 7000 (Fernbedienung) Die Fernbedienung (inkl. Ladestation) gibt es gratis dazu - sie ist plötzlich ausgefallen (kein Schlag oder Fall). Wahrscheinlich hat der Akku schlapp gemacht. Mitgeliefert wird ein B&O-kompatibles DIN auf Klinkenkabel mit (insbesondere gut für den Anschluss von Mobilgeräten/PC an den AUX-Eingang) sowie ein B&O-kompatibles DIN auf 2x Cinch-Paare für Ein- und Ausgang mit.
