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.
