US-690 12 Inch Gooseneck Dynamic Microphone General Description: The Electro-Voice US-690 is a cardioid, shock-mounted, gooseneck-supported, dynamic microphone. This microphone utilizes a revolutionary neodymium alloy to form the exclusive N/DYM magnet with four times the power potential of conventional microphone magnets. With a computer-optimized design, the N/DYM magnet structure is maximized in the US-690 to provide up to 6 dB more output sensitivity over conventional designs, while the more uniform magnetic field lowers distortion during peak sound pressure levels. The exceptional sensitivity of the US-690 combined with the inherently low noise of a dynamic transducer ensures a superior signal-to-noise ratio. A unique diaphragm design provides 50 percent more surface area than conventional designs and is reinforced to prevent “breakup.” The result is an extended high-frequency response with an open transparent sound quality that provides greater intelligibility for today's most demanding sound system. The uniform cardioid polar pattern of the US-690 ensures superior gain-before-feedback in live applications at all frequencies—compared with other directional microphones with widely varying polar characteristics. The US-690 is enclosed in a rugged Memraflex grille with Acoustifoam pop filter to virtually eliminate explosive breath sounds and wind noise. Coupled with a unique shock mount system which totally surrounds the microphone element, further reduces all forms of handling or mechanically induced noise, and makes the US690 the microphone of choice when ruggedness and performance are essential. Application The model US-690 gooseneck microphone was designed for use on lecterns as a high quality mixing console talkback microphone, or applications that require a plug-in gooseneck microphone. Operation The frequency response of the US-690 has been tailored for optimum performance where smooth, extended, highly intelligible sound character is required. The microphone output is balanced and low impedance. The dynamic element of the US-690 will provide reliable operation in humidity and temperature extremes— adverse conditions that would render condenser microphones useless—for years of trouble-free operation.

Frequency Response: Polar Response: Microphone Use and Placement Please note that micing techniques are a matter of personal preference. These are merely guidelines to assist in the placement of the microphone to gain optimal performance. Optimal Placement Zero to six inches from the windscreen, and on axis with the microphone. Spoken Word Five to ten inches from the windscreen, and on axis with the microphone. Standard Placement & Use Guidelines 1. Always point the microphone at the desired source of sound, and away from any unwanted sources. 2.The microphone should be located close to the sound...
