BeoLab 3500 was specially developed as a second-room loudspeaker in a Beolink® system. It was was the first-ever dedicated Beolink® speaker from Bang & Olufsen and effecively replaced the LCS 9000 (Local Control System) loudspeaker in the early 1990s.
Using this active loudspeaker a user could access various sources from a master system and adjust settings using a Beo4 remote control. For example, one could access and adjust the sound of a television via the BeoLab 3500, or listen and control CD or radio playing on a main room Bang & Olufsen music system. A small display, complete with clock and timer function (synchronised from the main system), informed the user about which source was playing. Using its standard bracket the long, thin speaker could be positioned high on the wall or on an optional table stand in rooms around the house. It was perfectly designed for use in a study, kitchen or bedroom.
Ideally the speaker could be used with BeoLink Wireless 1 which made the whole system easy to set up and very flexible to use. Accordingly a Power Link socket was fitted to ensure its compatibility with the wireless system.
BeoLab 3500 had two speakers at either side for stereo sound and an integrated Beolink® receiver-unit with red LED display in its centre for reception of remote control commands.
New drivers for BeoLab 3500 were incorporated as from June 2006. The speaker then included a 9 cm woofer and a 1,9 cm tweeter.
It was originally designed with a high-gloss aluminium cabinet and black fret. However, from the end of 2008 a white fret model was introduced to the model range.
