I think it sounds like a delayed (!!!) base filter function, but I'm
not sure. The base filters are independent, but the error is in both
mic's. That makes we wonder.
Dan's suggestion about a self-healing condensor is also plausible,
but both base filters are obviously affected and I don't understand
how that happens.
I don't think it is an interaction between the handle and recorder.
Send the handle here and I can have a look at it asap.
Klas.
