Loud hiss white noise solved


Recommended Posts

So I just tried to use my Helix live and got this very loud white noise or hissing sound from the XLR output.


We troubleshot the noise to the fact that the channel had phantom power on.


Turned off phantom power the noise was gone.


The helix is now dead silent, the front of house asked me if it was still powered on.......

I have Phantom power off and I'm still getting white noise/hiss.  Running 1.03.0 Firmware.  Running XLR's to a mixer, into studio monitors.  The gain on the mixer is not set high.  Any help appreciated.  Thanks,  Bill

I was still on the firmware before 1.03 and I was able to resolve this. Are you certain that phantom power is off?
