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.
