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.
