■ Preparing the speaker cables

3 Twist the bare wires tightly so the individual

strands are not splayed.

Once you have positioned the speakers, cut the 24.5-

meter (80 ft.) speaker cable into five cables for

connecting the front right/left speakers, center speaker

15 mm (5/8")

and surround right/left speakers.

1 Cut the supplied speaker cable to suitable

length for each speaker.

Good No Good

2 Remove about 15 mm (5/8") of insulation from

the end of each speaker cable.

Notes

• Make the speaker cables as short as possible. Do not

bundle or roll up excess cable.

• Be careful not to injure yourself while preparing the

speaker cables.

3 Rotate the speaker terminal clockwise to tighten

it.

4 Test the security of the connection by pulling

gently on the cable.

Notes

• Make sure the terminal is gripping the bare wire, not

the insulation.

• Make sure the bare wires do not touch each other, as

this could damage the speaker or amplifier.

• If the connections are faulty, you will hear no sound

from the speakers.

■ Connecting to an amplifier

Connect each speaker to the appropriate speaker terminals on your amplifier by using the cables you prepared earlier.

For details, see “Connection diagram” (page 5).

Make sure you connect the speakers with the correct polarity—positive (+) terminals to positive (+) terminals, and

negative (–) terminals to negative (–) terminals. If you get them crossed over, the sound will be unnatural and lack bass.

In your AV receiver’s speaker size settings, specify small (or “S”) for all of the NS-PA120 speakers.

Once you have connected all of the speakers, plug the amplifier and other AV components into suitable AC wall outlets.
