She needs to make sure that Phantom power is engaged on which ever hardware device is being used for input. (i.e.) mixer or professional sound card: also correct inputs and outputs are important when attempting to record audio. From within Sonar's track view property you can make these selections.

I no nothing about this microphone, are there buttons she needs to press on the microphone as there's no sound just a humming noise coming from her sound card when Sonar echo is on? Any thoughts will be welcome.
