I’m looking to Bose for info I can’t seem to locate. I have a AV3-2-1 series 2 media center with a SQUARE 13 pin connector cable from a Bose acoustimass module.
I am looking for pin out information for that cable and the speaker inputs.
can anyone help?

I posted several potentially helpful documents in this thread:

Also I have an internal circuit sketch of the IR input box the remote signal is received by posted earlier in that thread.

hope that helps you out
