I use the cable tester mentioned in my previous post to manage all this. It all works out very well, but before I got that tester (about 2.5 years ago) I was in the dark. I used a continuity meter tester, then, but it was really hard to do, and didn't give the kind of information that the big tester gives. The tester has a matrix of lights that give all the pin info, showing what pins connect to which ring, tip, or sleeve. I don't know how I managed all those years without it.Phil O wrote:Ok, so here's the problem as I see it. The XLR outputs on your MOTU unit are most likely differential (i.e., balanced), so each out has a GND, +, and -, for a total of 5 connections for stereo (GND common to both):
1) GND
2) + Left
3) - Left
4) + Right
5) - Right
The TRS input on the HA8000 has 2 single ended (i.e., unbalanced) signals, for a total of 3 connections:
1) GND
2) Left
3) Right
To connect to the HA8000 you need to short the (-) on each output to GND, making a total of three connections:
1) GND/- Left/- Right
2) + Left
3) + Right
I don't know if the 2 female-to-TRS mini is configured this way or not. If it is, you could cut off the mini and solder on a 1/4 inch TRS, but you'd need to check the internal connections first. Unfortunately, your best option is to make the cables yourself or have them made for you. Markertek will custom build for you, but I don't know what they charge.
Note: Those numbers are NOT pin numbers.
Good luck with this Shoosh. I understand your frustration.

Here are two cable/adapter combos that work for getting headphones from XLR Out ports to a headphone amp:
