The PB223 is for powering phantom powered microphones with 48VDC. Since the units use a 100KHz switching power supply there is no audio noise generated. They have output pull down resistors so they will work with any mixer and have 2DC jacks so several units can use one adapter. The PB223 powers two microphones.
