Peavey PSM-2 Unidirectional Electret Microphone (USED)
The PSM 2 is specifically designed for low profile, surface mounted microphone applications. The microphone consists of a wide range unidirectional condenser capsule, so mounted in its rugged housing that it becomes part of the acoustical boundary when placed on a flat reflective surface.
The excellent performance, low profile, and rugged construction of the PSM 2 make it an ideal choice for any sound reinforcement or recording application in which a unidirectional surface microphone may be an advantage - in footlight areas for stage productions, on conference tables or TV news desks, on church altars, as a "plant" microphone on walls or ceilings of sets, and in any number of related situations. In instrumental music applications it may be mounted to the inside of a grand piano lid, used in front of or inside kick drums, or in front of instrument amps.
