So I can learn, what's wrong with using a stereo plug to connect the devices?
I had picked up a stereo cable while waiting for my XPA2 to arrive. Posts on another forum said the stereo cable was needed for the trigger.
This was the first time using a trigger for me, so that's what I bought.
When I got the amp and installed it in my system with the stereo cable, it didn't work.
Ran out to Radio Shack and got the mono cable, and that worked.
ETA: The cable you posted is 1/8. I'm assuming that's equivalent to 3.5mm which is what you need (too early for me to do the math heh heh).
