Pre-adjusting the subwoofer vol-

Before you use the subwoofer, first adjust the vol-
ume balance between the subwoofer and the front
speakers by following the procedure below.
1.
Set the
VOLUME
control to minimum (0).
2.
Turn on the power to all other components.
3.
Press the
POWER
switch to the ON position.
The power indicator on the rear panel lights up

4.
Play a source that contains low-frequency
sounds. Adjust the amplifier’s volume control to
the desired listening level.

Increase the volume gradually to adjust the vol-
ume balance between the subwoofer and the
front speakers. In most cases, set the control to a
level at which you hear slightly more bass than
when the subwoofer is not used.
6.
Adjust the volume of the entire sound system
using the amplifier’s volume control.

If you replace the front speakers (NX-S120) with
other speakers, you must again balance the subwoofer
and surround speaker volume.
