I am having trouble with my NT-1 and AI-1.

When i first switched it on, everything works great and it pics up the mic and its all reasonable in terms of volume. After about 5-10 mins the mic output sound goes very quiet and the green light only comes on if u tap the mic and vocals are insanely quiet.

if you turn it off and on again it all goes back to normal for another 10 mins.

I have spent 3 days since receiving this microphone and it simply doesn't work.

Could it be a power issue from the USB.
