BooSTINg ThE BASS

Press the remote's Bass Boost button to enhance low-frequency
performance, resulting in bass with more impact, which you may prefer
while watching movies or listening to music. The OSD will display "Bass
On" as the sound mode. There is no harm in experimenting with this
control. Pressing the Bass Boost button again will return the soundbar's
normal low-frequency performance.
SUBWOOFER LEVEL CONTROL
Use the subwoofer's Level knob to balance the bass with the rest of the
sound. Play music or movies that you are familiar with, and adjust the
subwoofer's Level knob so the bass sounds balanced on both music and
films. Listen to several different music recordings and film soundtracks
that contain strong bass passages, and find a setting for the Level knob
that doesn't over-emphasize the bass or make it sound weak.
Once you find a setting for the subwoofer's Level knob that balances
the bass with the rest of the sound, you shouldn't have to change it.

SUBWOOFER CROSSOVER CONTROL

CROSSOVER
The subwoofer's Crossover control adjusts the subwoofer's cutoff
between 40Hz and 200Hz. The higher you set the Crossover control,
the higher in frequency the subwoofer will operate and the more its
bass will "overlap" that of the soundbar. This adjustment helps achieve
a smooth transition of bass frequencies between the subwoofer and the
soundbar for a variety of different rooms and subwoofer locations.
To set the Crossover control, listen for the smoothness of the bass. If
the bass seems too strong at certain frequencies, try a lower Crossover
control setting. If the bass seems too weak at certain frequencies, try a
higher Crossover control setting.

SUBWOOFER PHASE SWITCH
PHASE
This switch determines whether the subwoofer's piston-like action
moves in and out in phase with the speakers in the soundbar. If the
subwoofer were to play out of phase with the soundbar speakers, some
of the sound waves produced by the soundbar and subwoofer could
be canceled out at some frequencies, reducing bass performance
and sonic impact. This phenomenon depends in part on the relative
placement of the soundbar and subwoofer in the room.
Although there is no absolutely correct setting for the Phase switch, in
most cases it should be left in the "0°" position. When the subwoofer is
properly in phase with the soundbar speakers, the sound will be clearer
and have more impact. It will make percussive sounds like drums,
piano and plucked strings sound more lifelike. The best way to set the
Phase switch is to listen to music that you are familiar with and adjust
the switch so that drums and other percussive sounds have maximum
impact.
