Hi OPeeps!
you’ll need this adapter. there are a lot of cheap alternatives btw.

I use this setup :
Op1 -> cable 1/4 to rca -> behringer uca202 -> USB apple cck (camera connection kit).
I don’t know if my iPhone can record a Bluetooth audio but it would be cool to have :
Op1 -> “jack Bluetooth thing” Sending audio to iPhone wireless. Anyone tried that ?
I’ve got a Yamaha AG06 that, besides mixing, also works as an audio interface for my iPad. It has a separate USB port for power, so you can connect it straight to the CCK while powering it off a USB power bank. Pretty nifty for recording stuff away from … the grid.
P.s.: A digital frontier. I tried to picture clusters of information as they moved through the computer. What did they look like? Ships? Motorcycles? …
