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 an 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.
Notes
• Once the subwoofer volume has been set, you can leave the
subwoofer's VOLUME control set as it is and use your
amplifier's volume control to adjust the volume of the entire
system.
• If you replace the front/center speaker (NS-BR300) with
other speakers, you will need to re-adjust the subwoofer's
volume.
• The frequency characteristics graphs below show how the
subwoofer and front speakers work together to provide a
full-range sound.
