Parasound Halo Integrated.

Hi all, I need some help. I just bought a used one for use in a second system. One of the reasons I decided upon it was the fact that I thought it supported Airplay. I was looking to stream to it wirelessly from my Macbook Pro. I was thinking I could hook it into my home network and that would be all I needed to do. Obviously that's not the case so I hoping someone is in a similar situation and could lend me a hand in finding a way to stream to it wirelessly. Thanks in advance!!
