It sounds like you have the matter resolved. - But, personally, I like to keep my noise gate off. If I can help it anyways. I discovered when I used "XLR" to 1/4" Balanced & or Unbalanced (either will work) Into the board, The noise impact, well was too much. I was pretty bummed. And You may or may not have been doing this. - But, I switched to where i am coming out of my amp with "XLR", & into my board with "XLR". And now I am noise free. I do not need the use of a noise gate to be silent. - As long as I am not playing of course. And screaming when I do. LOL, Love it. Especially the fact that I have separate volume control between the amp & board itself. It's a first that I know of. Anyways , Maybe this helps? Good luck.
