Hello @Jharp,

I would recommend:
– Monitoring your Input channels to ensure that the noise is not coming from any of your mics or sources. You can do this by PAFLing your input channels and listening through the headphone output
– Make sure you have a good gain structure. This will ensure that you don’t have any unwanted noise floor.
– If you are outputting the signal from the mixer through an XLR output, which output bus are you outputting? The Main Mix? or have you created a separate Mix for this?, Make sure that your Mix Master Fader is in unity level and that your sent signals are also at a good level.
– Make sure that the input level at the camera is also the optimum.
– Monitor the signal coming into the camera by connecting your headphones on the camera to detect if at this point the noise is present.
– You may test the camera inputs by connecting any other XLR source into it and see if the noise is present, this will help you disregard the possibility of being the camera Input XLR’s sockets that are causing the noise.

Let us know how it goes,
Cheers.
Rafael

we will try it this Sunday. thank you

Make sure the camera does not have auto gain control engaged.

[Mike C]

In addition to the auto gain suggestion, should your camera have that option also you will want the camera XLR audio input set to line level.

On the ATEM turn off any unused audio inputs.

[jharp]

thank you all for the help and advice. i will try to do everything this sunday

[Mike C]

I took a much closer listen to the Feb12th morning video.
The audio feed itself sounded good, I could hear some hum in the back ground.

Try getting an isolation transformer to put inline between the mixer and the camera.
It’s not uncommon to need isolation between an audio and video system.

Something like this works well.
