OWNER’S MANUAL

CONSUMER PRECAUTIONS

Read these precautions carefully before installing your NS-IW480C speakers.



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.



YAMAHA recommends installing the speaker only in two-by-four wood frame or similar construction. The

instructions provided in this owner’s manual are intended specifically for this type of wall construction.



When installing your NS-IW480C in-ceiling speakers, be aware of the product weight (See specification page)

and the sturdiness of the material into which you are installing the speaker.



Be aware of any concealed studs, electrical wiring or plumbing in the wall or ceiling into which you are

installing the speakers. If you are not sure of a safe way to install these speakers, consult a professional
installer or a building contractor.



Never touch the woofer or tweeter units with your hands or expose them to excessive physical shock. If they

are dented or bent, the sound will be distorted.



Lower the power amplifier/receiver volume control before changing input sources. Never change input sources

(for example, FM to CD) at high listening levels. Always turn the receiver/amplifier unit off when installing or
removing any cables.



Anytime you note distortion, reduce the volume control on your power amplifier/receiver to a lower setting.

Never allow your power amplifier to be driven into “clipping”.



Secure placement or installation is the owner’s responsibility. YAMAHA shall not be liable for any accident

caused by improper placement or installation of speakers.

WARNING:

Installation shall be in accordance with the applicable section of the National Electrical Code, ANSI/NFPA 70,
and/or the National Fire Alarm Code, ANSI/NFPA 72, as applicable. The wiring method and compartment shall
be such as not to interfere with the operation of the speaker.

SPEAKER PLACEMENT

These speakers are not magnetically shielded. Avoid installing the speakers too close to your TV.

Stereo

For best stereo performance, install the left and right
speakers at equal distance from the listening position.
Each speaker should be separated by a distance of 6­10 ft.



Home Theater

Use these speakers for left and right surround
channels. Surround speakers should ideally be placed
behind the listening area, at least as far apart as the
front speakers and up to 2 additional feet apart per
side.
