I have just bought a secondhand Canon XM1 in mint condition. Supurb camera, but the onboard mic seems so quiet. When hooked up to the sound meters on the video, the sound does not go above -12db. I used to use pro broadcast camers with pro mics and the sound was always around 0db. (on automatic) Even my old domestic camcorders were about 0db. The sound is very good, just so quiet. (even normal talking about 3ft away). Any one know if this is normal levels for an onboard mic. I can not find any way of altering this (except adding an external mic). Is there any thing hidden in the menus? or anything else I am missing?
