Im. Using a MXL 990 pantom power mic running to my lexicon alpha interface and when i go to record a track i hear static in my vocal track .
He seems to have been able to record a vocal track, thus perhaps the mic is powered properly(?)
FWIW....There was another post where someone had an issue with crackling and was using a Nady SMPS-1X phantom power box. Don't know if the OP of the thread got it sorted out.
