But I'm pretty sure that you have to set up the input channel up to 48+ phantom power for it to work, and then also for safety make sure any plug in power is plugged into an input that has phantom power plugged off, or use a Rode vXLR in the XLR input jack that will convert Phantom Power to plug in power.
