Installation and Use Manual

The NEAR OCS1(B) Ceiling Loudspeaker is a full-range, wide dispersion system providing high­quality 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 bracket 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 100V high-impedance systems, as well as a low-impedance (16-ohm) posi­tion, are provided.

The OCS1 features a removable snap-lock input connector, providing easy wire
connection for input as well as loop-through to the next speaker.

IMPORTANT

The OCS1(B) is not an outdoor speaker.
Do not expose the speaker to rain or moisture.
The OCS1(B) should be installed by qualified personnel.
