It's probably a silly question, but are you sure you have the noise filter
turned off? It's there to get rid of LF wind noise, as far as I can tell. As
a design engineer with some experience I can't conceive of any technical
design tradeoffs which would limit the LF response. I agree with you, it
should be flat to 5Hz. Any preamp can do that - it's the top end that
sometimes stretches the designer and the components.


However I have another issue with the V1's sound. I have 6 of these cameras
which have probably been used a total of 100 times in the past 6 months. On 2
occasions the audio has gone unstable, resulting on first one channel dropping
out, then the other. This happened last week and I went about swapping mics
and cables to work out why one channel had disappeared. Then the other channel
went to high level white noise. I power cycled the camera and the white noise
went but one channel was still missing. I plugged my mics into one of the
other cameras and got on with the shoot, and quarantined the suspect camera.
However it hasn't played up since. Anyone else experienced this? I suspect
it was a HF instability brough on by hot patching mics, indicating an
inherently unstable design.
