For safe and proper use of the speaker:

• Positionthespeakerinalocationthatissolid,level,

smooth,andlow(withrespecttotheoor).

• Donotpushorapplypressuretothesideofthespeaker

Forsafetyreasons,usingcommerciallyavailableproducts

thatincreasestabilityinthespeakerisrecommended

(metalttingsorchains,etc.).

Notes

• Be sure to have another person support it.

• Pay extra attention to avoid scratching the

speaker’s surface.

• Be careful not to apply force to the side of the

speaker, otherwise the speaker may fall causing

damage to the speaker or personal injury.

• To avoid accidents resulting from tripping over

loose speaker cables, affix them to the oor.

• 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 at least

20 cm (8”) away from the TV. This is not an issue

with LCD and plasma TVs.

CONNECTIONS TO YOUR AMPLIFIER

Amplier

NS-F901 (L)

This speaker system is capable of standard connections and bi-wired connections. Before making

connections, make sure that the amplier is switched off.

■ CONNECTIONS

Youneedacommerciallyavailablespeakercable.

Thesizeand/ormaterialofaspeakercableaffectsonthe

soundquality.Therefore,werecommendyoutopurchase

ahigh-qualityspeakercabletoexerttheperformanceof

thisunit.

Notes

• Connect the (+) terminals on the amplier and the

speakers using one side of the cable. Connect the

(–) terminals on both components using the other

side of the cable.

• Connect one speaker to the left (L) terminals of

your amplier, and another speaker to the right (R)

terminals, making sure not to reverse the polarity

(+, –). If one speaker is connected with reversed

polarity, the sound will be unnatural and lack bass.

• When using an amplier with a rated output

power higher than the nominal input power of the

speaker, care should be taken never to exceed the

speaker’s maximum input.

• The speaker may be damaged if certain sounds

are continuously output at high volume level.

For example, if sine waves from a test disc, bass

sounds from electronic instruments, etc., are

continuously output, or when the stylus of a

turntable touches the surface of a disc, reduce the

volume level to prevent the speaker from being

damaged.

• Please refer to the owner’s manual that came with

your amplier or receiver.

How to connect the cables:

1 Loosentheknob.

2 Remove15mm(5/8”)ofinsulationfromeachendof

thecables,andtwisttheexposedconductorstogether

neatlyandtightly,asshownbelow.

4 Tightentheknobandsecurethecables.

5 Testthermnessoftheconnectionbypullinglightlyon

thecablesattheterminal.

Notes

• Do not let the bare speaker wires touch each other

as this could damage the speaker or the amplier,

or both of them.

• Do not insert the insulation coating into the hole.

The sound may not be produced.
