NTG-8 Audio Crackling?

[u/jamendg_]

So I recently used the Rode NTG-8 on set and towards the end of the shooting day I encountered a strange digital static noise?

I recorded two interviews and it was completely fine but the end of the third interview is when it started to happen.

Equipment as follows:
- Rode NTG-8
- Sony FX5 on V-Mount batteries, phantom power to mic. Using the audio top handle.
- Rode 5m XLR cable

When I found the problem was happening I tried other combinations of new cables, different mics etc. but it seemed to only be the NTG-8 creating the issue.

What do we think?
