Recently I have been getting some pretty bad interference when running two Sennheiser AVX wireless mics into a ZOOM H4n.

I shoot solo run and gun observational documentaries in a variety of live locations, situations with many people and chaotic.

The audio set ups I move between are the one mentioned above and a Rode NTG1 mic and Sennheiser AVX straight into my camera. I have never, or at least so infrequently I can't remember, got interference when running straight into the camera via xlr inputs.

Has anyone got any ideas, suggestions or better yet solutions to this problem? I have run tests in my home, a far more controlled space, and am unable to recreate the issue.

Happy to provide further info or answer questions in regards to this.

Appreciate any help you may have.
Cheers.
