Bump..!
I have a GS 3-2-1 system (series III, I think) and I am without the interconnect (acoustimass) link cable.
I'm not paying Bose ~$180AUD for the replacement...
kucor88 's post seems to confirm that this is possible, although his uses a different input? The one mine uses is the square, 15(?)-pin connection.
I'm just wondering if anyone is able to clarify his work, or provide a better (translated) explanation.
Thanks in advance
