Product Description

Thank you for choosing NEAR® Orbit Pendant Loudspeakers. You have purchased

one of the finest pendant loudspeakers available today, the NEAR Model OPS1.

Please familiarize yourself with this product by reading and reviewing the following
descriptions and diagrams in this manual.

All NEAR products include similar technical and design aspects that are unique to
the market. NEAR invented and patented the "spiderless" woofer (MLS™), which
features a high-gauss ferrofluid to guide the voice coil through the magnetic field.The
benefits over conventional woofers with cloth spiders are several, including the
ability to constantly adjust voice coil alignment, extend linear excursion, and the
most efficient path for cooling the voice coil.

In addition, the use of metal-alloy cone structures provides several benefits over the
usual paper or plastic cone, such as elimination of cone flex or "break-up" in the
operating ranges, additional thermal path for the voice coil to stay cool, and an
extremely stable cone structure unaffected by changes in temperature.

The NEAR OPS1 Pendant Loudspeaker is a full-range, wide dispersion system

providing overhead sound coverage where ceiling structures are high but the sound

needs to be closer to the audience/listener. An optional cable kit (CK10), suitable

for safety or main drop cable, is available.

Settings for both 70V and 100V high-impedance systems, as well as a low-impedance
(16-ohm) position, are provided.

The OPS1 features a removable snap-lock input connector, providing easy wire

connection for input as well as loop-through to the next speaker.

IMPORTANT

The OPS1 is not an outdoor speaker. Do not expose the speaker to rain or
moisture.The OPS1 should be installed by qualified personnel.
