Electro-Voice RE50N/D-B Dynamic Interview Microphone
RE50N/D RE50N/D-B Shock-Mounted, Omnidirectional Dynamic Microphones
- Powerful Electro-Voice neody-mium (N/DYM®) magnet results in greater output than with standard alnico magnets
- DynaDampTM shock-isolation system for low handling noise
- Rugged design
- Choose nonreflecting fawn beige or semigloss “camera” black
- Comes complete with stand clamp and vinyl pouch
Description
- The Electro-Voice RE50N/D and RE50N/D-B shock-mounted, dynamic omnidirectional microphones are offspring of the legendary RE50 microphone. Built with the same rugged de-sign as the RE50, the RE50N/D and RE50N/D-B feature a DynaDampTM shock mount for greater ruggedness and isolation, and a new neodymium N/DYM® magnet structure to provide increased sensitivity required in ex-acting professional applications.
- Ideally suited for handheld broadcast and sound reinforcement applications, the RE50N/D and RE50N/D-B have been built for superior isolation from mechanically in-duced noise. 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 high-mass internal acoustic chamber and microphone element, resulting in a degree of isolation un-precedented in an omnidirectional dynamic microphone.
- The transducer is protected through a unique interlocking concept, making the RE50N/D and 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 mag-netic particles by a carefully designed inte-gral windscreen and blast filter which also provides excellent protection from wind noise, excessive sibilance and annoying “P-popping.” The microphone’s MemraflexTM grille is designed to bounce back to its origi-nal shape when bumped or dropped.
- The RE50N/D in nonreflecting fawn beige or the RE50N/D-B in “camera” black are ideal for “on-camera” use. Both microphones are supplied with the 323S (black) stand adapter and a zippered, vinyl carrying pouch.
Architects’ and Engineers’ Specifications
- The microphone shall be a shock-mounted, omnidirectional, dynamic type with wide-range response uniform from 80 to 13,000 Hz.
