Lectro UM200C level control

Am I going crazy?

I seem to be needing to push the gain on my Lectro's as of late!
Usually, I would have them set approx 1-2 o'clock (with a COS-11), but
lately I have been running them around 4 o'clock to get the same
output. (limit LED lights up about 10% of the time) I've tried
differnt lavs (Tram, VT 400 and B6) all with similar results (although
the B6 is a little hotter)

Another possible clue is that when I play with the gain on the Tx (no
mic connected) the amount of noise or hiss jumps a bit at the 4
o'clock position (not a smooth and even transition)

Could the pots on my Tx's both be in need of replacement?

Hi Jason,
At 4 o'clock the wiper on the pot is leaving the carbon resistance
track and moving to the metal terminal. Basically, you are changing
from some fairly small resistance to no resistance at all. The bigger
question is why you are forced to operate in that region.

Since you have two units with "low gain", and a variety of mics, and
you are judging the gain (correctly) at the transmitter, I have no
clue. It seems odd that two units would do the same thing. Is there
any other common thing that has changed recently?
Best Regards,
