Hi, all:
I used a 3 channel Shure mixer, FP 33, for a couple of interviews. I
hooked the mixer to Canon XL1. Two wireless lavs were connected to the
mixer. During the test, I made sure that the level did not hit the
peaks; roll-off was on. While listening to the recording, it sounded a
little 'scratchy' so I reduced the camera's audio line in level. When
I looked at the waveform on the computer after the recording, it was
apparent that the waveform was clipped everywhere, both at the top and
at the bottom. I just don't understand why this happened if I ensured
that the master volume was set so that there would be no peaking. A
buddy told me with the Shure mixers, you have to set the master low
and adjust the individual channels if you want to increase the preamp
level.

What do you think could have caused this massive clipping? In the
headphones it did NOT sound as bad as it did on tape.

Thanks,
OMU

Problem is more likely the input stage of the Canon...as I recall they have
very little headroom, and it doesnt take much to get them sounding
scratchy...have you considered using an input limiter ?
