Hello,

I have a Bang OlufsenTV surround audio system Beosystem

Its a Tv with four column speakers which are powered and aplified as
you know by the bang olufsen beosystems, this speakers are not
connected
normaly to the output of a dolby surround system, but are driven by
the beosystem

Now I have changed TV to a flat screed LCD TV but I would like to
still be able to use the Bang Olufsen column speakers, how can I
achieve this? I need some kind of transducer to drive these speakers
from a standard dolby surround amplifier

Does any one sell a system that will input audio/video sources and
output them in surrond to the Bang Olufsen Beosystem speakers? Or sme
kind of device to put between surround amplifier and each speaker

You have a couple of ways to go.

B&O sells an adapter that goes from the 5 pin Beolink to traditional RCA
jacks you could use, but that would require you come up with a source
for the power on signal. Check the speakers, if they are like my Beolab
8000's, they have an RCA input, and a switch on them to select that
input instead of the Beolink one. The speakers then sense the presence
of a signal on the audio input (RCA) and switch on and off using that as
a trigger. Only downside to that if if there is a long silent spell on
the surrounds they will switch off. If the speakers have this RCA jack
on them, you'd just need a receiver that had line level outputs and run
an RCA cable between it and the speaker. I believe B&O still sells a
cable that connects to speaker level outputs and converts it down to
line level, but that's not entirely the best way to go about it.

B&O sells a thing called a Beosystem 1 (I think that's what it's called)
that is an AV center, it does all the surround sound processing and
video processing, lets you hook up to a non-B&O flat panel TV, but it's
like $6000 US. Pricey.

If you don't care about advanced surround sound and are happy with just
Pro-Logic, you might look for an older, used B&O AV7000. It is a
surround processor and switcher designed to be used with the old
5000/7000 B&O systems (rectangular boxes that preceded the current crop
of stuff). It has a 45 watt center channel output, and 4 Beolink outputs
for front and rear left and right. Video switching is limited to RCA
type composite video, so it's not up to modern video sources. I use an
AV7000 with a Panasonic plasma, I use the TV for video switching, and
run RCA level audio out from the TV to the AV7000, a pair of Beolab
8000's for the mains, and an amp run off the Beolink outputs for the rears.
