Im using a Rode nt1a for the first time. just plugged it in. im a total noob when it comes to ausio and microphones. i use audacity for frecording and a mobile pre usb as preamp conected through XLR cables with phantom power switched on. the mic looks like its working but the signal i can record is very low. almost not hearable wven though im only 20 to 30 cms away from the mic.
also in the manual it says not to unplugg Rode nt1a when plugged to power, but since my usb device alwa gets poer and cant be turned of by switch, how am i supposed to ever get it off safly ?
