Level
The subwoofer's Cutoff control adjusts the subwoofer's cutoff between
40Hz and 200Hz. The higher you set the Cutoff 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.
Cutoff
Level
To set the Cutoff control, listen for the smoothness of the bass. If the
bass seems too strong at certain frequencies, try a lower Cutoff control
setting. If the bass seems too weak at certain frequencies, try a higher
Cutoff control setting.
Phase
suBWOOFer PHase sWitcH
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.
Phase
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
Pairing
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.
