INSTALLATION

Before installation

The following is the recommended procedure for installing the speakers in a
ceiling. Please read it carefully before installation.
• Before you begin installation, read this owner's manual completely and consult
your local building codes. If you have any doubt, contact your dealer or a
qualified audio/video installer.
• Before installing the speakers, run the speaker cables to the installation
location.
CAUTION
• When installing the speakers, do not touch the center of the drive unit with your
hands or expose them to excessive physical shock. If they are dented, the
sound will be distorted.
• Be aware of any concealed studs, electrical wiring or plumbing in the ceiling into
which you are installing the speaker. If you are not sure of a safe way to install
this speaker, consult a professional installer or a building contractor.
• When installing your NS-IC400 in-ceiling speakers, be aware of the product
weight (See specification page) and the sturdiness of the material into which
you are installing the speakers.
• Placing the speakers too close to a CRT-type TV may impair the picture color or
cause a buzzing noise. In this case, move the speakers away from the TV. This
is not an issue with LCD and plasma TVs.
NOTE
• If you wish to paint the speaker grille, refer to page 10 "PAINTING THE SPEAKER
GRILLE" before proceeding.
Ceiling board thickness and clearance space above ceiling
• Check to ensure that the area you are installing the speaker is free of any
ceiling joints or studs by tapping the ceiling or using a stud finder.
• Make sure that there is sufficient space on the ceiling for installation and that
there are no obstructions such as ducts, pipes, etc. See the following chart for
external product dimensions and ceiling installation measurements.
• The thickness required for the ceiling boards is 5 – 30 mm (1/4" – 1-1/8").
