Thank you for choosing NEAR Orbit Loudspeakers. You have purchased one of the®
finest ceiling loudspeakers available today, the NEAR Model OCS . Please familiarize1
yourself with this product by reading and reviewing the 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 OCS Ceiling Loudspeaker is a full-range, wide dispersion system providing1
high-quality background and foreground music. It can be installed in either suspended
ceiling structures or hard surfaces such as sheetrock. It comes ready to install with
integral swinging arm clamps. An optional mounting bracket (TBCR) is available for
additional support (recommended for all suspended ceiling applications). The brack-
et can also be used for new construction ceilings, providing a cutout guide behind
the sheetrock surface and as a C-ring to stiffen the edges of the cutout opening.
A variety of speaker power levels are easily selected via a front panel rotary switch.
Settings for both 70V and 00V high-impedance systems, as well as a low-impedance1
(16-ohm) position, are provided.
The OCS features a removable snap-lock input connector, providing easy wire 1
connection for input as well as loop-through to the next speaker.
IMPORTANT
The OCS is not an outdoor speaker. Do not expose the speaker to rain or 1
moisture. The OCS1should be installed by qualified personnel.
