Hi and welcome to this forum

Did you authorise the new iPad? I haven't heard of any compatibility issues with UC Surface and iPads. You may have to set up a wired connection with a computer running UC to authorise the (wireless) iPad.

Thanks for the reply SwitchBack. This isn't something I had to do in the past. I used to have an iPad Air 2, and that would connect to my RM16AI as soon as it was on the correct wifi network. According to the RM16AI tech specs page the iPad Air 4 I have now isn't compatible. It just seems unbelievable to me.

Maybe at the time those tech specs were written iPad Air 2 was the latest and greatest around? I wouldn't give up on your new iPad yet. Also remember that wireless devices need to be authorised only once so you may have forgotten about it. If UC Surface can run on your iPad then I can't see why it wouldn't work with your RM16AI.

Suggestion: Make a wired connection from a laptop/computer running UC to the router that connects the mixer (wired) to the iPad (WiFi). Then check if the UC GUI gives you options to grant the iPad access. If the iPad doesn't show up at all then check if it's properly logged on to the router's LAN

Hey Switchback. I managed to get myself up and running, but not in any way that’s useful for others to know, but I felt I should log on and let you know what happened.

The new iPad I had bought stopped working and I had to return it, so unable to do any further testing I chose not to take the risk, and got myself a 1st gen iPad Pro. It works, perfectly, with no access granting necessary.

Thanks for your help though, I wish I’d been able to test your idea because I’d like to know for the future.

Anyway here’s to many more years with the RM16AI Incidentally I really think it’s a great piece of kit, I’ve used it for years and it’s never skipped a beat, and it’s so well built, construction is much better than the Soundcraft or Behringer offerings.
