General Description:
The Electro-Voice US690 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 US690 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 US690 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 US690 ensures
superior gain-before-feedback in live applications at all
frequencies—compared with other directional
microphones with widely varying polar characteristics.
The US690 is enclosed in a rugged Memraflex
TM
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 US690 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 US690 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 US690 will provide reliable
operation in humidity and temperature extremes—
adverse conditions that would render condenser
microphones useless—for years of trouble-free
operation.

2.The microphone should be located close to the sound source to minimize interference from other potential sound sources. 3. Use the 3-to-1 rule when using multiple microphones. Place each microphone three times farther from other microphones as from the desired sound source.
