Read these precautions carefully before operating your NS-AP2400 speakers.
Since these speakers can be wall mounted, it is essential that they are firmly secured.
Be sure to consult a reliable source about the best type of hanger for your particular
wall's construction. Secure installation is the purchaser's responsibility.
Do not attach them to thin plywood or soft wall surface materials as the screws may tear
free, causing the speakers to fall and be damaged, or result in personal injury.
Do not fasten the speakers to walls with nails, adhesives, or other unsafe hardware.
Long-term use and vibrations may cause them to pull free.
Do not place the speakers where they are liable to be knocked over or struck by falling
objects. Stable placement will also ensure better sound performance.
Placing the speakers on the same stand or shelf as a turntable can result in feedback.
This speaker features a magnetically shielded design, but there is still a chance that
placing it too close to a TV set might impair picture color. Should this happen, move the
speaker away from the TV set.
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 input 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".
Do not attempt to clean the speakers with chemical solvents as this might damage the
finish. To clean wipe with a dry, soft cloth.
To prevent the enclosure from warping or discoloring, do not place the speakers where
they will be exposed to direct sunlight or excessive humidity.

channels of a Dolby DIGITAL

contain a lot of very low frequency sounds, we suggest using these speakers in
conjunction with one or more powered subwoofers to get the maximum performance from
your sound system.

surround system. Since surround systems often
To assure low distortion on program peaks, your amplifier or receiver should be capable of
delivering at least 10 watts RMS (continuous sine-wave power) per channel. This speaker
can be used safely with amplifiers rated at up to 30 watts RMS per channel.
Amplifiers rated at higher than 30 watts RMS (continuous sine-wave power) per channel
must be used with care.
CONNECTIONS
Check to make sure that the power has been turned off before making connections.
Connect the (+) terminal of the amplifier to the (+) terminal of the Speaker.
Connect the (-) terminal of the amplifier to the (-) terminal of the Speaker.
Reversing polarity (+/-) will result in unnatural sound reproduction.
PROCEDURE
For connections, keep the speaker cords as short as possible. Do not bundle or roll up the
excess part of the cords. If the connections are faulty, no sound will be heard from the
speakers. Make sure that the + and – polarity markings of the speaker cords are observed
and set correctly. If these cords are reversed, the sound will be unnatural and lack bass.
Main/center/rear speakers
One side of the provided speaker cord has
white line and the other side has no line.
Connect the (+) terminals on both the speaker
and the amplifier using the side with a white
line.
Connect the (-) terminals on both components
using the side with no line.
Notes
Do not let the bare speaker wires touch each other as this could damage the speaker or
the amplifier, or both of them.
