V-Raptor and wireless audio issue

[joel pelet]

Hello,
I'm facing a big problem with my v-raptor. I'd like to use it with wireless audio microphones.
I tried with several brand. Sennheiser 6000 serie (6042 receiver and SK6000 transmitter), Sennheiser AVX, Wysicom (MPR52-ENG receiver and MTP40S transmitter) and Lectrosonic.

When the receivers are placed next to the camera there are a lot of cuts in the transmission as soon as the transmitter is more than 2 meters away there are cuts. The camera generates a lot of interference.
If I move the receiver away from the camera about one meter the transmission returns to normal.
The wifi of the camera is off. I don't know why this camera generates so much interferences. I also tried these microphones with DSMC2 cameras and there is no problem.
Lectrosonic is the only brand that has had no problem.
Has anyone ever experienced this kind of problem ?
Thanks for your help.

Joel, I will check tonight. I have several different Sennheiser packs. I'll let you know what I find. I will say I had a warranty replacement because of audio issues so hopefully this isn't the case for you.

I encounter similar issues with my Canon C500 Mark II and Sennheiser wireless packs. I was hoping my V-RAPTOR (arriving next week) would solve this problem.

Wow! I didn't know this was a thing - good to know so I can look out for it as I have a pair of C500's and a V-Raptor but I also use Lectro wireless so it seems like Joel mentioned that they don't seem to show the issue. I suppose the V-Raptor potentially generating some interference as it has the WiFi control built-in makes more sense but the C500 does not (unless you've added the USB dongle) so I'd be very curious as to what it causing the problem your C500.

All that said, I ran into an issue recently where if I had my video transmitter plugged in via D-Tap to the camera's V-Mount it would cause constant audio interface and if I ran the TX power separately the problem immediately went away so perhaps you both could go down that route for the source?

I hadn't specified it, but I always powered the receivers separately from the camera.
I have contacted RED support for this issue, awaiting a response from them.

It's a common problem with high RF generators like cameras. Power can also be an issue. Shielding is becoming more and more problematic and only integrated solutions (camera slot, Arri sound module....) usually tackle those problems. It's not a RED (only)problem and I don't know if they can resolve those problems.
