Does anyone know of a wireless iPod interface? Something like a wireless DI box that I can plug in an 1/8" plug for an iPod or laptop, or any other .mp3 player? Prefer something with just an 1/8" stereo plug on a short three or four foot cable that connects tot he transmitter. Distance is maybe 60-ish feet or so. I'm looking to use this for instances of talking head or preshow lecture set ups where someone may be giving a talk and want to play some music examples from an .mp3 player or laptop without having to string XLR cable all the way across a lecture room.
