Question

Constant Buzzing In Microphone Even When Unplugged

Mar 6, 2016 3:25PM PST

As the title states there is a constant buzzing / humming in my microphone even when the microphone is unplugged. I'm running an Excelvan BM-800 Condenser Microphone to a innogear phantom power box and then straight to my pc via 3.5 usb dongle or just to the microphone input jack.
Some things i've tried are listed below
1.) Moved the power strip to a different outlet to make sure it wasn't a ground issue (however i sometimes get a ground loop buzz but i cant find the source, happens very rarely though.)

2.) Unplugged a harddrive, some fans, and a DVD Drive to reassure myself it wasn't anything caused by mechanical noise from inside the pc itself.

3.) Moved my microphone around the room because one forum said it could be an issue relating to (electromagnetic?) interference.

4.)Unplugged the microphone. When i do that the buzzing is still there and at the same volume.

5.) Used a laptop, same outcome.

6.)Rolled up in a ball and cried. (not really but it's almost come to that)

PC Specs:
AMD Athlon X4 860k (overclocked)
Corsair H60 Liquid CPU Cooler
MSI A68HM-GRENADE Micro ATX Motherboard
AMD Radeon R7 250x 1GB
8 GB DDR3-1600 RAM
XFX TS 550W 80+ Gold PSU
Windows 10

Any help is greatly appreciated! Thanks!

Thanks for the reply. Although, do you think an RFI choke might be of any use? Heard some people have had some luck with that...

you say microphone, but do you mean speaker? Is it a microphone powered from a wall plug instead of the USB on the computer?
