Canon 7D & T2i Auto Gain Control Kill With an iPod.

Here is a neat little fix for the AGC on the Canon 7D and Canon Rebel T2i. By adding a tone generator to one side of the audio via an iPod Shuffle, “Mike B”  was able to effectively kill the AGC on the Canon 7D. This should work for any Canon HDSLR with AGC and mic input. Thanks to Vision Wrangler via Twitter for bringing this to my attention.
