According to my notes the DPA 4060 functions best at 48 =B14V but can run o=
n as low as 10V and draws around 0.5 mA. I would assume the recorder can at=
least provide that much times two. So if the recorder has the same symptom=

I would not be surprised if it was some strange grounding issue, perhaps re=

make) contact. I am hardly an expert but recall reading something similar s=
ome years back, relating to the DAD6001BC.
Odd indeed.
