HIGH PITCH NOISE

Postby Sirch24 » Tue Oct 15, 2019 3:10 am

Hello...I recently have been having trouble recording. I keep getting a high pitch humming noise. I've tried changing mics...I use a newer phantom power to connect usb to my mac. I never had an issue before. I tried changing all the cords and a new phantom power but no change. I have a sample of that it sounds like. Please help

What do you mean by "a newer phantom power" ? Are you using the USB output from a mixer? if you are some of the cheaper ones have issues over USB, like a whine, or a hum, as Tim says, we need a sample.

I think the OP means a Neewer phantom power unit. https://www.amazon.co.uk/Neewer-1-Chann ... 9087&psc=1

It's pretty unlikely to be a phantom power issue, and much more likely to be a ground-loop problem, probably between the monitor speakers and interface....

To diagnose we'll need to know precise details of all the equipment in the set up and how it is connected together -- and how it is all powered from the mains.

I think you're probably right Wonks but what USB interface are you using @Sirch24?
