Audio Glich on Both Channels – at the same time???????
I had a shoot 2 days ago using my HPX170. I ran a Senn Lav into one channel and a Rode shotgun into the other.
Prior to the shoot, I tested the room and picked a clean frequency. Once the shoot began – a presentation, there were moments of distortion coming through the lav. They would last from 1/2 a second to a second and garble the audio.
I assumed that there was interference in the air or that it had to do with the distance between the transmitter and the receiver.
Sitting down to edit the material, I have discovered that this glitch is on both channels. When the lav distorts, the shotgun looses volume (about 5 db).
I have never experienced an issue like this with my shooting set-up, which I have used regularly for over a year.
All batteries were new and the camera battery was fully charged.
Any ideas to help troubleshoot this mystery would be great.
Thanks.
Alex

Completely turn off the lav track, still have distorted boom?

It’s possible something in the building emitted a strong emf pulse. It could have been a spark or a transmitter of some sort. Sennheiser has a very helpful chart of frequency use by city. In the future, you can check that list for clear freqs in your shooting location.
