M55RP

Common name: Fostex M55RP

Production Status: Discontinued / Vintage

The M55RP is a cardioid microphone specifically designed for handheld use. The M55RP is internally shock-mounted exhibiting extremely low handling noise. The integral XLR connector is prewired with high quality cable. Includes P303 Isomount featuring a quick-disconnect, single button lock and individual measurement chart. The Isomount is finished in no-glare studio grey. The M55RP is part of the RP Laboratory Series. RP stands for Regular Phase. This system actuates the whole surface of the diaphragm with the same phase like a piston. A fine aluminium ribbon-wire coil is etched on to the surface of an extremely thin polyester film diaphragm suspended in a powerful magnetic field provided by rare-earth samarium-cobalt magnets. The diaphragm-coil assembly is 80% lighter than a typical dynamic element resulting in very high sensitivity. The unique suspension system and planar diaphragm exhibit very low distorsion even at high SPL levels.
