Two Channel, Battery Operated 48V Phantom Power Supply


The battery unit supplies one or two microphones with 48 V phantom powering (P48). The maximum current drain is 5 mA for each microphone.

The audio outputs are dc-free. Therefore, no transformer is needed to connect to unbalanced inputs. The unit has two XLR 5 connections which can be split to XLR 3 connectors with AC 20 and AC 21 adapter cables.

Maximum length of operation depends on the type of battery and the current drain of the microphone. A microphone requiring e.g. 2 mA can be operated at least 20 hours with one alkaline battery.


  • Output Voltage: +/- 48V DC
  • Maximum Current: max. 2 x 5mA
  • Battery: 9-volt
  • Weight: 310 g (without battery)
  • Dimensions: 1.45 x 3.15 x 4.01" (37 x 80 x 102mm) (HxWxD)
