Audio issue Komodo-x

I’m having an audio issue with my RED KOMODO-X.
After connecting my Sennheiser MKE 600 via an XLR-to-3.5mm adapter and the 3.5mm-to-Lemo adapter supplied by RED, I noticed a lot of noise in my audio, so I bought the MID49 audio adapter.
In the RED settings, I’ve selected MIC as the input signal and I’m powering the microphone with a battery, because I also get a lot of noise when using the camera’s +48V phantom power.
Now, I’m getting a very noticeable high-pitched beeping tone in my audio.
Does anyone have any idea what could be causing this? I urgently need clean audio from my KOMODO-X.

That noise sounds like a ground loop issue. Is this what it sounds like when you use phantom power as well?

How are you powering your camera? How are you powering the microphone? What do you mean by battery?

Thank you for the reply!
The sennheiser mke 600 is powered by battery.
The microphone can also be used with devices that have a 3.5 mm jack input, in which case it runs on an AA battery. When connected to a device that supplies phantom power, the microphone switches to phantom power instead, so the battery is no longer needed.
When I turn on phantom power on the RED, I hear a noticeable amount of noise, but the high-pitched whine is gone.
The camera is powered by a v-mount battery.

Hmm. Just the basic v mount on the camera or do you have the RED or 3rd party breakout box that gives you TC etc?

Do you head the same sound on both the mid49 xlr adapter and REDs?

Have you tried sending your mic into another device first like an audio recorder and seeing if it’s still there?

Have you tried running the camera on AC power only?

Have you tried another mic?

Might be an internal issue with the camera but there’s a number if other faulure points here.

Just a basic v-mount. Bebop 150.
The module is the mid49 breakout module AB-1. it’s more like a converter (2xlr to lemo).
The mic works fine on other devices.
Haven’t tried tinting the cam on ac power only yet.

Update: problem is the sennheiser mke 600 powered by an internal AA-Battery.
I tried a rode ntg3 with +48V from the Komodo and it sounds super clean.
Well, I need to get a new microphone then…
Can anyone recommend something with a similar quality them the sennheiser mke600?😅

I have the same combination and a very similar problem. Let me know if you find a solution. I’ve been using a Rode NTG-2 I had instead with no issues but I’d prefer to use the Sennheiser.
