Is there a way to get the airplay digital audio signal from an iphone5 to a PA speaker without some type of large devise intended to sit at home on a desk? I use the PA speakers for outdoor events and the airplay receiver has to be attached to the speaker somehow. Currently am using a $50 Bluetooth devise (with a 1' wire running from the devise to the 1/4" TRL speaker input), but sound quality is noticeably worse than plugging the iphone directly into the speaker, presumably due to the lower bitrate of Bluetooth. If there is some better solution than airplay I may use that as well. I play most of the music from Spotify and a friend was suggesting having an android devise attached to the speaker with a remote desktop program running (I guess apple doesn't have remote desktop software?) That setup would also require bringing a wireless router that connects the speaker-android devise with my mobile android devise. Any help is appreciated.
