I'm having the same Canon dilemma and I have learned that the GL-1 does not have the manual audio gain control features that the XL1 has. There is an "attenuator" but I'm not sure of the tech specs. I'm wonderind if the gain controls on a Beechtek or Studio 1 XLR adapter would solve the problem.(posted 8958 days ago)If anyone has these audio answers let us know.
