CONSUMER PRECAUTIONS

CONNECTIONS TO THE AMPLIFIER OR RECEIVER

USING WITH YAMAHA ACTIVE SERVO

PROCESSING SUBWOOFERS

Read these precautions carefully before operating your NS-AP1400 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.

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.

● 

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.

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.

This YAMAHA speaker is designed to give excellent balanced sound performance on all 

channels of a Dolby DIGITAL

TM

 or DTS

TM

 surround system. Since surround systems often 

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.

Please refer to your subwoofer owner’s manual for proper connection instructions.

Do not let the bare speaker wires touch each other as this could damage the speaker or 
the amplifier, or both of them.

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.

① 

Press and hold the terminal’s tab, as 
shown the figure.

② 

Insert the bare wire end properly in 
to the terminal hole.
[Remove approx. 10mm(3/8”) 
insulation from the speaker cord.]

③ 

Release your finger from the tab to 
allow it to lock securely on the cord’s 
wire end.

④ 

Test the firmness of the connection 
by pulling lightly on the cord at the 
terminal.
