(1990) Mono power amplifier, 1x150W, Speaker link, Power link, sold in pairs
Type numbers: 1731, 1732, 1733, 1734, 1735
Beolab 200 replaced Beolab 150 at the same time as the Beolab Penta 2 loudspeaker replaced the original Beolab Penta. Despite the name suggesting otherwise, the power output remained the same at 150W. The difference was that a new type of connector, “Power link”, was fitted. To make room for this the sprung input connectors for loudspeaker cable were removed, though the “Speaker link” connectors remained as a loudspeaker level input. The RCA line level socket also remained. Text copyright © Beocentral. Unauthorised reproduction prohibited.
Power link was and excellent arrangement, it carried both left and right signals, as well and switching commands and data for the displays (if fitted) in one simple 8 pin DIN lead. Because both left and right signals were present in the cable, the loudspeakers could be connected in a chain, reducing the amount of cable and simplifying installation. All that was needed was to “tell” the amplifier whether it was “left” or “right”, and in the case of the Beolab 200 and Beolab Penta 2 (and 3), this was done using a small slide switch located in the pop-out panel at the front (incorrectly referred to as a “transformer” in contemporary catalogues). Because the power link system allowed devices to be connected in a chain, two identical sockets were fitted, one for “in”, one for “out”, though as they were connected precisely in parallel inside, which way round this was done was a matter of indifference. Also fitted to the socket panel under the amplifier was a switch marked “audio/video”, but this was used in connection with the display panels of the Penta 2 and 3 loudspeaker and had no function with the Beolab 200. Because power link carried switching signals as well as data, the amplifiers could be switched on and off instantly was required. Previously all switching had relied on the presence or absence of a signal, and a delay had been included before switch-off so as to prevent the amplifiers reverting to standby during a short break in a piece of music.

Beolab 200 suffered from the same lack of practical purpose as had the Beolab 150. The loudspeaker of choice was now the Beovox RL 7000, an updated form of the Beovox RL 140. The Beocenter 2500, which had no built-in amplifier of its own, would have been well served by the Beolab 200, but this was a very rare combination indeed. As B&O moved further towards loudspeakers with built-in amplifiers, the Beolab 200 was quietly withdrawn and not replaced. Text copyright © Beocentral. Unauthorised reproduction prohibited.
