The Amx works with an iPhone. Set up your camera connection kit and whatever else you need. *
The last thing to plug in just before opening the app is the amx.
My next setup with dvs using the amx as a sound card for external mode. Main out deck1 to ch1 on the denon mixer and headphone out into ch2 on the Denon mixer.
You will need a battery like in the first pic or a powered hub like in the second pic.
