The FP-MPA2 from RDL is the ideal choice in any applications where phantom power needs to be provided to powered microphones. Two identical circuits are provided, with connections through XLR jacks.
The microphone is connected to the module through the female XLR jack. The selected phantom voltage is applied to this jack. The microphone signal output is available on a male XLR. Phantom is blocked from this output jack. The phantom voltage is individually selectable for each input.
A three position switch is provided for choosing 12V, 24V or 48V. Some microphones operating on 24V phantom perform optimally with higher value buildout resistances. For these particular powered microphones, a second switch is provided to select the optimum current. The appropriate voltages are generated through a low-noise dc-dc converter and regulator circuits. Each phantom output is short-circuit protected.
The FP-MPA2's low profile and compact size permit mounting in confined spaces and in various locations in equipment racks. The location of the input/output jacks permits high-density mounting against flat surfaces while maintaining accessibility to the connectors.
