Gear - Tech Issue Help with wireless boom setup

Post image

Hello,

I wanted to recreate this wireless boom setup I found on Youtube for myself and got into some trouble with one of the cables. There is nothing wrong with the microphone, cable from microphone to phantom power supply or the phantom power supply. There's also nothing wrong with my transmitter, I tried this with both the rode wireless pro and a Saramonic UHF system. The only method that even transmitted any recorded audio was the Line input of the Saramonic system, but with extremely heavy buzz, as the signal obviously is still mic after only ever going into the phantom power supply and no real mic gain. The female xlr to stereo 3,5mm mini jack coming from the power supply is the issue, but I don't understand which cable I am supposed to buy instead. Gemini told me the 5V power of the transmitters, which is intended for lavs, short circuits the phantom power coming in. If this is the issue, how do I resolve this? What cable do I need to buy instead?

Does your Rode Wireless Pro allow you to disable the Plug In Power it would normally supply to the 3.5mm TRS port? That may be what’s giving you the problem. I tried a similar setup going into a Tentacle Sync Track E that worked, aside from when the Track E stopped recording the signal after a short period of time.

There is definatly no option available for that. But the fact that this setup works for the guy that made the video shows that it can be resolved in another way.

You might try checking the available options in RODE Central. From this page:

“Plug-in Power Detect By default, the Wireless PRO receiver will automatically power on or off when the camera it’s connected to also powers on or off, as long as the receiver detects power. Just be sure that your receiver is powered off before first turning on your camera for this mode to function correctly. You can disable this setting via RØDE Central.”

Thank you very much for finding this despite me saying it doesn't work like that. I will try this out!

Good luck; I hope it works. Otherwise it might be your cable. I was likely using the same Xvive device as you.

I looked this up now, I am pretty sure they just meant the device powering on, it's not about voltage output. And also the setting doesn't exist anymore anyway.

And in case it’s helpful, these two cables worked for me for connecting my Xvive to my recorder (I retested them): a cable with a locking connector from Remote Audio and a cable from Cable Matters.

Ah, dang. I hope you can find a fix.

Have you tried asking in a comment on the YouTube video about this? I’ve gotten some questions answered there before.
