I did mean the mini jack for headphones. So I think I have a pre-Anniversery Beosound. Thank you for your help.

Thank you so much for your help. The AUX works just fine now. =) Unfortunately, I am still not able to locate the mini-TRS. Is it possible that there is a version of the Beosound 2000 without the mini-TRS?

Where is the mini TRS port on the Beosound? I read on many websites that there is one, but I can't find it. Also, what kind of cable is needed for the AUX? Thanks in advance for the help.
