I just saw this app and have been wanting an app to control individual monitors every since my church got the X Air 18. My question is do you have to have wifi or will the app use the wifi(Or whatever you call it) that is built in to the soundboard?
You can use the WiFi built into the board. But you should know that it's risky to use the built-in WiFi at a show. It's very flakey. Most people use an external 5Ghz router at shows.
This is not an XAir Monitor Mixer thing, you'll have the same problem with any of Behringer's apps. The built-in WiFi is just very weak, and 2.4GHz is a crowded bandwidth.
It looks like you're new here. If you want to get involved, click one of these buttons!
