Fixing Noise Issue

[steven8579]

I have a buzzing issue when I stream. I know for certain that it is the new LED lights that are in the church. They cause a pretty big buzzing sound. I used the Noise Suppression filter but when I use this filter sometimes it takes away too much sound and cuts out the sound of the organ when it's low. Is there any way to drown out this buzzing sound? When someone is talking, you can hear the buzzing under the person's voice. The best solution I've been able to use so far is Noise Suppression and using the artificial gain from OBS while leaving the gain on the audio interface turned down. There has to be a better solution. I'm using OBS Studio with a Behringer FCA1616 audio interface and PTZ Optics USB Camera. Any help would be appreciated.

The computer I use is currently at church so I can't provide a log file. I will attach one tomorrow when I go there.

Thanks,
Steven

How are you inputting sound into your OBS computer? Directly from microphone > Behringer ?

I have a line in from our house PA system into my OBS computer and was getting a hum/buzz sound. Yes, the suppression filter worked but it made the overall sound experience horrible.

After much experimentation, I ended up with a ground loop isolator between my XLR line in and the XLR to USB device used to get the sound into the computer. Solved it entirely.

I'm sure one of the more savvy sound engineer types herein will have more in depth options, but that's what worked for me.

Thanks so much for your quick reply. I’m connecting the house sound system from the audio out jack directly to the behringer. The behringer is connected to my Mac with a USB cable. Do you mind elaborating a little more on what a ground loop isolator is and how you set one up? At this point I’d try anything that could help get that humming sound out of my feed.

It wasn’t as bad until they put in the brand new LED lights in the whole church. That’s when I really started noticing it.

I use my house sound through two different line ins. ONe is an XLR and one is a 1/8".

I use this one for the 1/8": https://www.amazon.com/gp/product/B01L1NP7YI/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

For the XLR, it is similar to this. I can get the exact model when I'm next at the church: https://www.amazon.com/Whirlwind-ISOXL-Line-Level-Transformer-Connectors/dp/B0047Y5YLU/ref=sr_1_13?crid=PBP2U5QAGWP8&dchild=1&keywords=xlr+ground+loop+isolator&qid=1616214233&s=electronics&sprefix=XLR+ground+loo,electronics,221&sr=1-13

Sorry, cannot edit my OP. Here is the XLR isolation transformer we use: https://www.bhphotovideo.com/c/product/135096-REG/Pro_Co_Sound_ITX_ITX_Isolation_Tranformer_for.html
