Orbit Pendant Speaker

OPS1

Installation and Use Manual

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.

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 the environment.

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.Also, a conversion chart for speaker use in 25V sys­tems is provided in this manual.

All ORBIT models feature a removable snap-lock input connector, providing easy
wire connection for input as well as loop-through to the next speaker.
