p Sub woofer phase polarity
S.W PHASE [NORMAL]
Initial setting : NORMAL
Set the sub woofer phase polarity.
There is usually no problem when the sub woofer phase
polarity is set to "NORMAL". However, depending on the
type of front speakers, the position of the sub woofer, and
the cut-off frequency of the sub woofer, setting the phase
polarity to "REVERSE" may produce better bass.
Besides bass reproduction, the richness and tightness of
the overall sound may also be affected. While listening
from the main listening position, select the setting that
best suits your environment.
