Hey everyone!
Long time lurker, first time poster. Let me first say that I have been extremely grateful for the wealth of information everyone has posted in these forums, it has been a great place for information. Unfortunately I am running into a problem that I haven't seen discussed yet.
I am still relatively new (compared to 95% of you) and recently am being called on more and more sets with wireless follow focus systems. I am finding that I am picking up the sound of the follow focus motor when the AC is pulling focus. The lavs and boom are both picking it up when shooting indoors, but it isn't usually a problem outdoors. I originally thought that maybe it was a bad follow focus, but since have noticed that it is a persistent problem.
The only things I can think of that could be causing this are my gain staging, or maybe quiet actors in enclosed space. I'd love some community input so I can get rid of the problem, though, it's been driving me nuts. Thanks in advance for any advice you can offer!
Gear being used:
Zoom F8
Lectrosonics Lmb and SMQV tx (typically 23-27 gain)
Lectrosonics Src and 411A (-12 output, have tested up to +5)
Sanken Cos-11 Black and Red dot versions
Sennheiser MKH416 and 50
