I have previously done this but not recently because I have a wireless and its permanently connected into my input - solved!
I have to say I've not had too many pressure moments recently as I've worked the bugs out e.g. I had issues with my remote and I've now switched to ethercon. I have also got my output on a patch panel so I never connect to the wrong output. My speaker cable is also permanently attached to my KPA to also eliminate that :)...
