This design enables it to produce the warmest, most natural sound available from any type of studio microphone. However, it also makes this the most sensitive and fragile studio microphone available. All ribbon microphones require special care or they will be seriously damaged. In order to ensure long life for your RSM-3 please always follow these 4 precautions: 1. Always protect your RSM-3 from any hard knocks, such as from dropping the mic, or not properly padding in shipment, as such jolts can destroy the ribbon assembly. Prevent any sudden or strong blasts of air movement from ever reaching your microphone, as they can tear and destroy the fragile ribbon. When using, always utilize a pop filter, such as the optional Nady MPF-6, to prevent any percussive sounds from damaging the ribbon. Such filters also prevent damage from moisture from mouth spray; 3. Never intentionally or accidentally apply any phantom power from your mixer or a phantom power supply to your RSM-3 as it can burn up the ribbon. Please always check carefully before connecting your ribbon mic that there is no phantom power being provided to the RSM-3. [. . . ] After that, the standard Nady warranty will only apply to defects in materials and workmanship other than the ribbon assembly. It these are damaged, please contact the Nady Service Department for a quote for replacement of the ribbon assembly.
