Operating the speaker terminals
1
Press and hold the terminal tab.
2
Insert the bare wire.
3
Release the tab so that it closes securely on the
bare wire, not the insulation.
4
Test the security of the connection by pulling
gently on the cable.
Notes
• Make sure the bare wires do not touch each other, as
this could damage the speaker or the amplifier.
• If the connections are faulty, you will hear no sound
from the speakers.
■
Connecting the speakers
Connect each speaker to the appropriate speaker
terminals on your amplifier by using the cables you
prepared earlier. See the “Connection diagram” on
page 3 for reference.
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-P40 speakers.
If you’re connecting the subwoofer to a Yamaha DSP
amplifier or AV receiver, connect to its SUBWOOFER
or LOW PASS output.
Connecting the power cables
Once you’ve completed all of the speaker and
subwoofer connections, plug the subwoofer, amplifier,
and your other AV components into suitable AC wall
outlets.

VOLTAGE SELECTOR (China, Asia, and
General models)
Make sure the VOLTAGE SELECTOR is set to the
correct voltage for your area (110–120/220–240 V
AC, 50/60 Hz). Ask your dealer if you are not sure.
Warning
Disconnect the power cable before changing the
VOLTAGE SELECTOR setting.
Setting the subwoofer volume
The very first time you use the subwoofer, you need to
set the volume balance between the subwoofer and the
front speakers as follows.
1
Turn on your other AV components.
2
Set the subwoofer’s VOLUME control to
minimum (0).
3
Set the subwoofer’s POWER switch to ON.
The power indicator on the rear panel lights up.
4
Play a audio source that contains low-
frequency bass sounds. Set the amplifier’s
volume control to a suitable level.
5
Turn the subwoofer’s VOLUME control up
gradually until you achieve a good balance
between the subwoofer and the other speakers.
