So, I have an old Beomaster 4500, and I'd like to get my computer connected to it.

I have an old tape recorder that we don't use, and it had these 7-DIN -> 4xRCA connectors in each end.

Does anyone have the pin order I have to use to get audio from a 3.5mm plug from my computer to those RCA connectors?

I've tried to fiddle with it, so far the sound either comes from only one speaker and sounds completely rubbish, usually with high and low sounds completely cut out, or it just doesn't work.
 

remove the tape recorder from the equation, and just use a din to mini lead (aka ipod adapter) -just run it from your sound card to the aux in on the bm4500.

worked fine for me...

The tape recorder isn't in use.

Where would I get that iPod adapter thingy ? 

Best would be to get to know which DIN pin is connected to left, right and ground in 3.5mm jack as I could do it myself... 

If you will use the Audio Aux Link socket PIN 3 is left, PIN 5 right and PIN 2 ground (input for audiomaster).

reread your post, my bad.

user: lazerwave on ebay sells them, less than 20usd -that is where i bought mine. works great. not only can you connect your puter, you can obviously connect an ipod or better yet... an airport express!
