[. . . ] Ideally suited for handheld broadcast and sound reinforcement applications, the RE50N/D-B has been built for superior isolation from mechanically induced noise. Handling noise, clothing noise, and even cord shock are isolated from the microphone element. [. . . ] Handling noise, clothing noise, and even cord shock are isolated from the microphone element. Within the microphone's machined-aluminum outercasing, a DynaDampTM shock mount (manufactured using an advanced vibration-isolation material) surrounds the highmass internal acoustic chamber and microphone element, resulting in a degree of isolation unprecedented in an omnidirectional dynamic microphone. The transducer is protected through a unique interlocking concept, making the RE50N/D-B practically indestructible with normal use. The transducer, fitted within a high-mass internal case, is shock-isolated within an attractive external case, therefore protecting the transducer from sudden shock. The microphone's diaphragm permits a very smooth response over a wide frequency range, yet it withstands high humidity and temperature extremes, corrosive effects of salt air and severe mechanical shocks. The diaphragm is protected from dust and magnetic particles by a carefully designed integral windscreen and blast filter which also provides excellent protection from wind noise, excessive sibilance and annoying "P-popping. " The microphone's MemraflexTMgrille is designed to bounce back to its original shape when bumped or dropped.
