I’m so happy I went with the Niles 1/8 mono trigger cables. The moral of the story here is that sometimes, you try and save a few dollars and in the end you end up spending more. For some things, it’s not worth being budget conscious–especially if the difference is only a dollar or two.
Here is the completed setup. I added a cap on top of the diodes and positive wires.
Here is a view of the unit. You can see the single trigger that I would connect to the Anthem will trigger my two Proceed amplifiers.
