Beovision LX4500

BeoVision

Production: 1990 - 03/1992

Designer: David Lewis

Replacing Beovision LX2502, the Beovision LX4500 was a luxurious 25″ multistandard colour television with the benefit of stereo reception.

Fitted with contrast screen, Teletext and the possibility of using a motorised stand, the television had a very wide range of colour options available for it. It used the Beolink 1000 remote control terminal and offered hi-fi quality sound.

For a novelty value it was able to keep tabs on other TV programmes and sources by way of a Picture-in-Picture module when it could show a small TV image  in one corner of its screen. Likewise it could also offer to the viewer a choice of either four, nine or sixteen miniature TV clips displaying just what the other stations had to offer.

Datalink connections were built in to link the set with another suitable Bang & Olufsen audio or video product, and Power Link sockets were provided for which to add a pair of Beolab active speakers like Beolab Penta III.

The Beovision LX 4500 was eventually surpassed by the arrival of Beovision LX 5000.
