No specs can be found on the built in wireless, but I have recently been corresponding with Soundcraft via email. I had a question about running the demo on the iPad, and consequently have just asked about the wireless capabilities of the Ui-16.
They responded in a very timely fashion, so I should hear back soon. But at least with an Ethernet port, I presume any quality dual band wireless router can be used with it. Long & McQuade here have some in stock. (Ui-16) It would be fun to go check it out, just the same. New Toys.
This app seems to be fairly easy to navigate for a "newbie" on it. But MF is still the easiest to use out of all of them IMHO. Don't think I'm straying from the Mackie stable just yet though. Time will tell.
Gotta have an open mind just the same. Although you do lose more of your brain that way!
