Frequently Asked Questions - RE50N/D-B ELECTRO-VOICE

What type of microphone is the Electro-Voice RE50N/D-B?

It is a dynamic, omnidirectional microphone with a neodymium magnet (N/DYM) and DynaDamp shock mount.

Is the RE50N/D-B suitable for outdoor broadcast use?

Yes, its integral windscreen and blast filter reduce wind noise and plosives, making it ideal for handheld broadcast in various environments.

Does the RE50N/D-B require phantom power?

No, it is a passive dynamic microphone and does not need any external power.

What is the output connector type and wiring?

It uses a 3-pin XLR connector; pin 2 is positive with positive pressure on the diaphragm (referenced to pin 3).

How do I clean the RE50N/D-B?

Wipe the exterior with a damp cloth. Do not use solvents or abrasive cleaners. The Memraflex grille can handle minor bumps.

What accessories are included with the microphone?

It comes with a 323S stand adapter (black) and a zippered vinyl carrying pouch.

Can the RE50N/D-B be mounted on a standard mic stand?

Yes, the included stand adapter fits standard 5/8"-27 threaded stands. The shank diameter is 25 mm (1 in).

What is the frequency response of the RE50N/D-B?

The frequency response is 80 Hz to 13,000 Hz, providing a smooth, wide-range sound ideal for speech and vocals.

Is the RE50N/D-B durable for rough handling?

Yes, it features a rugged aluminum outer case, DynaDamp shock isolation, a high-mass internal chamber, and a Memraflex grille that bounces back from impacts.

What optional accessories are available for the RE50N/D-B?

Options include the 376 Charcoal Windscreen, 379-1 Black Windscreen, 379-2 Red Windscreen, and 422A Desk Stand.

USER MANUAL RE50N/D-B ELECTRO-VOICE

• Powerful Electro-Voice neodymium (N/DYM®) magnet results in greater output than with standard alnico magnets
• DynaDamp™ shock-isolation system for low handling noise
• Rugged design
• Finished in semigloss "camera" black
• Comes complete with stand clamp and vinyl pouch

General Description:

The Electro-Voice® RE50N/D-B shock-mounted, dynamic omnidirectional microphone is an offspring of the legendary RE50 microphone. Built with the same rugged design as the RE50, the RE50N/D-B features a DynaDamp™ shock mount for greater ruggedness and isolation, and a new neodymium N/DYM® magnet structure to provide increased sensitivity required in exacting professional applications. 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. Within the microphone's machined-aluminum outercasing, a DynaDamp™ 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 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 sibalance and annoying "P-popping." The microphone's Memraflex™ grille is designed to bounce back to its original shape when bumped or dropped.
