Sound Devices A20 Tx on Boom interference

[cstauffer]

Has anyone else had any interference in the form of audio ducking out while using the Sound Devices A20 Tx on Boom? Has anyone discovered the cause? I am suspecting some gear on the camera, possibly focus and/or aperture control systems, but nothing definitive yet. Hard to get time to chase it down when you are shooting a TV Series! Thanks everyone...

What do you do to fix the problem? Change freqs or does it randomly happen on any freq?

you absolutely sure it’s your TX? I had my boom signal cutting out briefly every now and then but very often right after „aaand action“ was called. Turned out my Mixer Fader for the Boom had a dead spot I was hitting

Derek, i tried changing freqs to no avail. Still happens.

 

Matthias, I am fairly certain it is the Tx. Set radios aren't doing it. It happens at random times but seem to happen when near a camera with the boom.

Could be a faulty BNC cable on the camera monitor/Teradek. They can spray a lot of RF.

Good luck chasing that down. I would get in touch with sound devices and try to work with them.
