Hello,
First off I'm new here so sorry if I posted this in the wrong section. I wasn't sure if this should go here or in technical reference.
I work as an on set sound mixer/boom op and every once and a while my recorder picks up this really strange buzzing noise. I've been doing some googling and can't seem to find other people with this problem.
At first I thought it might be the lavs picking up some rogue wireless signal but it's coming through the boom track.
I run a Sennheiser MKH 50 into a K-Tek pole with an internal wire into my Zoom F8 portable recorder with a standard XLR cable.
It works perfectly like 98% of the time but every once in a while starts picking up this buzzing noise that sounds like a fly buzzing mixed with electric current. It usually works fine if I turn it off and turn it back on but it's still frustrating that it will ruin a take occasionally and I have no idea why. I assume it's an issue with the recorder but could it be an issue with the mic or phantom power?
I've attached a sample of a take where it started acting up.
Any advice on how to fix or even identify the problem would be fantastic.
Thanks in advance,
Louis
