I’ve got a problem with CAD U39 USB Microphone.
It produces some kind of static noise at -48db even if it’s turned off with a selector on it.
I’ve tried different USB-sockets on different computers (laptop and desktop) with different USB cords. I’ve tried laptop connected to the socket and on battery. All other recording devices are disabled.
I have not problem with the ground connection, however I tried to ground the desktops's case.
I've made a huge googling and I don't know what else I can try.
What do you think, is my microphone defected and it’s simply its feature?
PS. I’m on Windows 10.
I'm looking forward to any response,
With best regards,
