This setting is found in the audio settings of the Atem Software Control. You can choose between Mic or Line level but I don't understand this third option.

The 3.5mm audio inputs on the ATEM Mini & Mini Pro/ISO/Extreme can supply "bias voltage" for electret condenser microphones. Typically between 3VDC and 5VDC, this is not the same as +48VDC phantom power. The bias voltage is a switchable option because dynamic microphones do not need it and can be damaged by it.

Plug in power is 5v bias voltage applied to the input like phantom jr.

Good Luck

Phantom?? It's not balanced so that can't be. It's a stereo L/R minijack.

it is for microphones like lavalier - some needs power over 3,5mm stereo plug

Learn something or don't.

Thanks, I didn’t knew that. I’m only famous with 48V Phantom power for normal condensers. But can’t you destroy the output of a device when using the minijack of the Atem as a stereo input?

I doubt it , the 5v bias power is usually fed from a high resistance source maybe 5kohms ( thus very low current capability ) and the output from from a line jack will be around 100 to 600 ohms ( much lower ).
