My understanding is that the BL6002 (unlike the Beolab 6000, which I have) lack the RCA input, and only have Powerlink inputs?
While I don’t have the same speakers I do have the 6000s, and I have a Beocenter 9000, and I have connected then successfully in the past. I was able to connect them with RCA-to-RCA cables because my BL6000s have an RCA ‘line’ input as well as Powerlink.
I’d ask Steve at Sounds Heavenly if he has the cables for that, if I were you!
