How do i use Airplay with this receiver, and also how to turn the ethernet port into a wireless coonetion for wifi?

 

I have Denon 2112 CI w air play.
I also have a URC 450 remote w IPOD macro.
I press the URC IPOD macro then Listen function.
You then adjust volume and channel {song in your IPOD}.
It works but FYI ...
Wireless can cause gaps and mp3 sound is only 8 bit words {mono}. So its not Permo Sound.
FWIW - CD stereo is 16 bit words and DVD-A 5.1 is 24 bit words.

I would stay HDMI cable over wireless.
