Hi matapan,
Welcome to Beoworld! Yes, this is popular and easy to set up.
The best option if you have a non-B&O TV and multiple speakers is to connect the speakers to either Beosound Theatre, or to a non-B&O AV receiver with RCA pre-out sockets fitted. I would suggest looking at the Marantz Cinema 70S or NR1711, Pioneer SC-LX59, Denon AVC-X3700H, Yamaha RX-A880 or RX-V785 AV processors/receivers, all of which have audio pre-out sockets for easy connection of Beolab speakers for a Dolby surround sound setup.
Your Beosound system can then connect to the CD input of the AV receiver to play to the speakers, plus you have surround sound when using the TV.
Please ask at my sponsor link below if you need specific help with connections for your setup.
Kind regards, Steve.
