Atem Mini issues

I am using the Atem Mini for church. I only have to input connected and today it started randomly switching between the input. No one was touching it when it happened. Is this a glitch, is there something else I need to do with the setup?

That is not normal and I would not expect it to be a setup issue.

If this happens again I would recommend contacting support via email or phone - see the options at the bottom of the page here: https://www.blackmagicdesign.com/suppor ... -switchers

Check MIDI control is turned off. If it's enabled and you have some random MIDI activity the ATEM can go a bit whacky.
