I've tried all the videos that were posted showing what they did. They all showed the same thing( pluging a 3.5m from thew headphone port of the Yeti to the Mic Port on the GOXLR. I've done that and still not picking up the audio.

Someone please help

I have a set of Samson C02 condenser microphones. When I plug one of them into my GoXLR Mini I get this noise.

I only get it when 48V is on(Condenser duh.) The sound in the file shows itself with 48V on and gain turned up pretty far in the software(60+ dBish.) I get it with both microphones in the set.

I get it when the GoXLR mini is plugged in the back of my PC, when it's plugged into the front pannel, when it's connected through a powered USB hub and even when it's connected to my wife's laptop. So I'm starting to think it's not my PC.

I do not get it if I plug in a dynamic microphone, even if I switch on 48V for no reason. 

I do not get it when I connect a dynamic microphone via a Cloudlifter, despite this device requiring 48V to add the extra gain.

I do not get this sound with the same microphones but another audio interface that is also bus powered(Roland Quad Capture)

Eternally greatful for any input anyone may have. At first I thought it was some sort of grounding issue with USB in my computer, but when the issue also cropped up testing with the wife's laptop my suspicions went elsewhere. Unfortunately these two Samson mics are the only condenser mics in the house right now. I tested with two different dynamic mics.

Hi,

I'm having an issue with my Go XLR where it skips the startup sequence and just goes straight to everything blue. None of the faders move nor does it light up in the usual rainbow fashion.

Its not detected by my PC either which leads me to think its a Power or USB connectivity issue. I do know its an issue with the GO XLR and not my PC. 

Sometimes when I add power only the 'X' lights up as well.

Ive uploaded a video to show what happens. 

Thanks
