As some members on here will know, I'm attempting to get quadraphonic sound from my system, and recently bought a lovely Beogram 6000 from Beojunkie and a superb Beomaster 3400 from Lifestyle AV. My dealer has been playing around with them, and we know that the BG6000 works through a different amp and the BM3400 works with a different turntable. However, my dealer is struggling to connect the two together - he's not sure what type of cable it requires, or where he could obtain one. Can anybody help us?

It attaches to the input marked 4 and works with the Phono selector. The button iunder the slide panel needs to be selecting 4ch. The Beogram has a 5 pin DIN plug with all 5 pins being used. The user manual for the 3400 is on site.
