Excellent point. I forgot to mention that I've tried a -10db in-line
pad, but the problem is still there -- slightly reduced. Changing the
"mic sens" settings on the recorder also does not completely eliminate
it. That's one of a couple reasons I suspect that the Sony ADC simply
cannot resolve certain low-frequency signals above a certain level.
Rolling off the low end a little bit going into the machine is the
answer.

Yes. As I indicated, I've replicated the problem with a pair of Crown
GLM-100 E mics. I also have a pair of ancient Sony ECM155s which
deliver very little low end and do not trigger the "bottoming out"
under any circumstances. The 183s are more likely to do it, I suspect,
because of their nice low end response.

The same wiring scheme as for PIP, but terminating in a male XLR, so I
use only one channel of the ART for a pair. Being not much of an
electronics guy, I stumbled onto that idea in a moment of dumb "what
if" curiosity, but found that it worked fine. No audible improvements,
but more power (up to a point) is supposed to increase headroom, and
this seems to be the case from the little bit of testing I've done.
