No, I expected audio that's at LEAST as good as my $2000 VX2000 video
camera. And it's not unreasonable to expect the audio on a $4800 camera with
XLR balanced, phantom-powered jacks to be almost as good as a $200 hand held
recorder.
The fact is, this is a DIGITAL recorder, and as such, it's pretty hard to
introduce non-linearity in a normally-linear digital audio system. There is
no technical reason why the camera audio should not be flat to 5Hz. Heck,
I'd even be okay with -1dB @20hz. But -32.7dB @20Hz is a sign of something
seriously wrong. Even analog taperecorders do better than this.
Listen to the comparison files of on-location audio I recorded with both the
$4800 V1U and a $200 cheap hand-held portable recorder here, under the
orange paragraph:

I record symphony orchestras, and for that I use a truckload of high end
digital recording gear. But last month I was at a parade where I had to be
mobile and could not cart around a wheelbarrow load of storage batteries,
inverters and digital recording systems. It would have been nice if the
audio quality from my pair of Neumann U87s were not so godawfully decimated
by the low- and mid-cut filtering in the V1U.
I learned my lesson on that one and now carry around this kludge of a camera
with a digital recorder permanently bolted to the top of it. It looks
rediculous and draws a lot of eyeballs in public places, and it's a PitA to
have to deal with synching and downloading all the extra files in
postproduction, but until Sony fixes this joke of an audio system, I and
others will have to live with the inconvenience, that I thought I would be
free of by choosing the V1U over the FX7.

Unfortunately, there was no rental available here, so I could not pre-test.
Anyway, it has a digital recording system, and everyone knows digital is
flat from DC to Nyquist. Sony must have deliberately neutered the audio on
this camera for marketing reasons. I can think of no way you can screw up a
digital recording system other than to intentionally and at considerable
cost, add in components to introduce nonlinearity. I'll bet that it would
cost LESS to make the audio flat, than it costs to put in this bell curve
filter.
You people that think a camera shouldn't have good audio need to get into
the 21st century with your thinking. This isn't analog tape with linear
track audio anymore! Digital is flat from DC to half the sample rate clock.
These vestiges of old are built in insults to us all.
