Specifications

■ Operating the speaker terminals

1 Rotate the speaker terminal counterclockwise to loosen it.

English

2 Insert the bare wire.

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 the “Connection diagram” (page 4).

For the surround and surround back speakers only, connect one speaker to the left (marked L) terminals of your

amplifier or receiver, and another speaker to the right (marked R) terminals.

Please refer to the owner’s manual that came with your amplifier or receiver.

Notes

• 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 speakers.

• 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.

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

• When using an amplifier 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.

■ When using a banana plug

1 Tighten the terminal knob.

2 Simply insert the banana plug into the terminal.

■ Center speaker (NS-C150)

■ Surround speakers (NS-B150)
