What makes this static "click"

Report · Jul 27, 2018

Hi all,

We've been running into a problem more and more recently that I'm trying to find an answer to, but can't, and was wondering if you could help.

We do a lot of interviews and we have been getting a static click sporadically throughout the interview (maybe every 15 secs) and I'm trying to figure out if it's the mic, the cables, the a-box, or the cameras. It's not a huge problem, they are easily healed away, but I'd like to know why it's happening and why it's seemingly getting worse.

We are getting it on both cameras. Running two shotguns (Sennheiser MKH's) into two Red Scarlets W's via A-boxes. Both have these clicks.

We also run a lav, but that's been clean.

The good news is the clicks don't sync up. Is this just the nature of the beast?

They look like a couple pixel hard red line that runs the extent of the Spectral Freq Display.

I'm a self learned audio person, and try to find the answers online from other peoples questions before admitting my noobness to the masses, but I havent been able to find it in the words I use. So if this is a laughable question I'm sorry. If there is a thread that you can point me to, that would be much obliged.

Just looking at what piece of hardware is responsible.

Thanks in advance.

Jamie

How (if at all) have you synced the Red Scarletts? Two clocks running almost in sync will often produce whacking great glitches when the difference between them exceeds the sync 'granuality' (IOW when the sample clocks drift more than a sample apart).
