You need a '5-Pin DIN' to RCA cable. Most electronic stores should keep them, or AV stores. If they don't have them in stock, you should be able to get hold of one! Connect it into the A.Tape, A.Tape 2, Aux or CD connections on your amplifier (not the PHONO connection!) and press the correct button on your remote control (to access the Aux connection, it's TV on a BeoLink 1000 remote).
