custom installation professional. Be sure that the installer possesses sufficient skill, the prop-
er tools, knowledge of local fire and building codes, and a familiarity with the structure of the
building (especially wall and/or ceiling materials, layouts, electrical and plumbing lines, etc.).

Installation: Existing Construction (retrofitting finished ceilings)
Warning: Exercise caution when drilling into existing ceilings. Do not drill
through electrical wires, pipes, conduits, heating or air conditioning ducts. If you
feel resistance while drilling, stop immediately. Do not install the speaker into a
drop ceiling or soft ceiling, as this type of construction will not support its weight.

Connections
Before connecting speakers to your system, it is important that you turn off the power to
your amplifier / receiver to avoid damage to the equipment. Before installing the NHT in-ceiling speaker, map out the wiring
paths between the speakers and the amplifier. Make sure that the speaker wire does not rest on sharp or pointed objects.
When permanently installing wire inside walls, be sure to use wire that is rated for in-wall use and has
special jacketing for fire prevention. In the U.S., the U.L. standard is CL-2, CL-3 and CM wire, and in Canada the CSA standard
is FT4 wire. The wire should be run in accordance with National Electrical Code and any applicable local building codes.
Be sure to connect both the left and right speakers "in-phase." That is, the Positive + (red) terminal on the amplifier output
must be connected to the corresponding Positive + (red) terminal on the speaker. Likewise with the Negative - (black) termi-
nals.
