Hi. It seems nobody answers X3 related problems now. I am trying to record vocals with my x3 live using Rode NT-1A Condenser Mic and Behringer Phantom power supplier for 48V. Now when i am using the presets i get this really bad buzzing sound from my x3 (i have attached a recorded audio file of the buzzing sound below). Even if i remove the mic and plugin nothing, the sound is still there when input is selected as mic. There is no sound when the input is selected to guitar. But when i select the aux, the sound starts and when its turned to mic mode, its even more aggressive. I checked the same in my friend's x3, he too is having the same problem. It would be really kind if someone cud help.
