US690

12-Inch Gooseneck,

Dynamic Microphone

Description

The Electro-Voice US690, US690F and

US690F-S are cardioid, shock-mounted, gooseneck-supported, dynamic microphones.

These microphones utilize 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 series 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 series combined with the inherently low noise of a dynamic transducer ensures a superior signal-to-noise ratio. To further reduce noise, a highly effective humbucking coil is used to cancel hum from lighting and other sources.

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 series ensures superior gain-beforefeedback in live applications at all frequencies—compared with other directional microphones with widely varying polar characteristics.

The US690 series are enclosed in a rugged

Memraflex TM grille with Acoustifoam TM 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 series the microphones 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.

The model US690F gooseneck microphone was designed to panel-mount in fixed installations where a high-performance, rugged, non-removable microphone is required. The microphone has a permanently attached, twoconductor shielded cable, six feet long, to permit ease of installation.

The model US690F-S gooseneck microphone was designed to be surface-mounted in fixed installations where a high-performance, rugged, field-installable microphone is required. The microphone has a permanently attached, two-conductor, shielded cable, six feet long, to permit ease of installation.

Operation

The frequency response of the US690 series 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 series will provide reliable operation in humidity and temperature extremes—adverse conditions that would render condenser microphones useless—for years of trouble-free operation.

Mounting Instructions for US690F

Select microphone location, taking care that there are no obstructions under panel which could be damaged; panel thickness may not exceed 1 /

2

inch. Drill a 3 /

4

-in. hole at micro-

2 phone location, drop cable through the hole and position the microphone assembly.

Secure assembly with included panel washer and retaining nut (see Figure 6). Attach connector. For correct wire placement for threepin balanced or 1 /

4

-in. phone plug balanced or unbalanced termination, see the wiring diagrams in Figure 5.

Mounting Instructions for US690F-S

Select microphone location, taking care that there are no obstructions under the surface if the cable is to be routed through the surface.

The flange is slotted to provide the option for cable exit above the mounting surface.

Attach the template provided to the surface at the mounting locations. Pilot drill the three holes for the flange. Now optionally drill the hole through in the center if the cable is to pass through the surface. Drop cable through the hole and position the microphone assembly. Secure assembly with user-supplied screws . Attach connector. For correct wire placement for three-pin balanced or 1 /
