(NS-SW300 only)
MOVIE:
When a movie type source is played, the low-frequency effects are enhanced to allow
listeners to enjoy a more powerful sound. (The sound will be richer and deeper.)
MUSIC:
When an ordinary music source is played, the excessive low-frequency components are
cut off to make the sound clearer. (The sound will carry less bass and reproduce the
melody line more clearly.)
NOTE
Once the volume balance between the subwoofer and the front speakers is adjusted, you can
adjust the volume of your entire sound system by using the amplifier's volume control.
However, if you replace the front speakers, you will need to make this adjustment again.

In most situations, set this switch to select the reverse mode. However, depending
on your speaker systems or listening condition, there may be a case when better
sound quality is obtained by selecting the normal mode. Select the better mode by
monitoring the sound.
