- OS: Windows 10
Audio Interface: UMC404HD (connected to computer via USB 2.0)
Microphone: AT2020 (connected to interface via XLR male to female)
Before I continue, here is a picture of the front and back of the UMC404HD, so there is a little less ambiguity in my descriptions. Also, I want to apologize in advance; I am not much of an audio guy, so my knowledge here is pretty limited. Please let me know if I am making any mistakes.
Things I have tried:
- - The XLR is plugged in snugly on each end.
- Phantom power is turned on.
- Drivers are installed (found here; I have tried both "UMC Driver 3.29.0 for Windows 7 to 10", and "Windows Driver V2.23.0", same results for each).
- Gain knob is set in at the middle (the line is pointing straight up).
- Line/Inst is set to line.
- Pad is off.
- "BEHRINGER UMC404HD 192k" is the default recording device; I have disabled all other devices.
- Levels are set to maximum in Windows.
- The USB cable has been plugged into 3 different ports on the computer, two USB 2 and one USB 3. The two USB 2 produced fine audio output, the USB 3 seemed to clip occasionally.
- - Neither the clip nor signal light for any of the inputs are active/lit. When I turn on phantom power after waiting with it off for a minute or so, the signal light will flash briefly for each input, but that is the only activity I have seen.
- There is a loud buzzing sound when gain is set to max. This does get picked up by Audacity and Windows, and is reduced slightly when the pad button is pressed.
- When touching the body of the microphone, a buzzing can be heard that changes intensity depending how much of my hand is touching it. This is audible even at medium gain.
- When the mic is unplugged, there is no buzzing whatsoever even at maximum gain.
