Hi Tim,
Well, as a production sound mixer AND videographer, I’ll give it to you as good news/bad news: The good news is that the major companies that make wireless systems, Lectrosonics, Zaxcom, Audio Technica, and Sony all have new dual-channel, true diversity, slot receivers, out. That’s where one receiver can receive two independent signals from audio transmitters. The bad news, is that the 3000, like all cameras still only have two audio inputs (three if you count the front mic), even though, they can record up to eight tracks of audio. There was a big discussion on this over on the professional audio forum, too. And no matter what anyone posts here or tells you, there is NO WAY to record more than two totally independent (un-mixed) tracks of audio on any currently produced camera.
