Alright, im a real noob at this so it would be really nice if anyone who decides to reply, reply with the greatest detail possible.

I currently have a beolab 3500 and 8000 that I would like to hook up to my computer (if thats even possible). These speakers were bought back in the 90s in Europe and the only entrances they have seem to be for the powerlink cable (8 pins), apart from the power cable itself. So I ask, is there anyway I can hook these two up to my pc or stereo and if so, what exactly do I need to do?

Thanks guys
 

Any questions ask. 

BeoLab 3500 is a lost cause in this instance.  It is a special purpose 'network' speaker mean for use on B&O's proprietary multi-room network, with an apppropriate B&O audio or video master.

Happily, the BeoLab 8000 has a traditional RCA-style line level input, below the flip-out panel for AC and PowerLink.  Set the input switch to Line, and you're off and running!
