When the subwoofer is properly in phase with the soundbar speakers, the sound will be 

clearer and have more impact. In-phase performance will make percussive sounds like 

drums, piano and plucked strings sound more lifelike. Although there is no absolutely 

correct setting for the subwoofer’s Phase switch, in most cases it should be left in the 

“Normal” position. 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.

For the best sound, we recommend turning your TV’s built-in speakers off. Consult your 

TV’s owner’s manual to find out how to do it. If there is no way to turn your TV’s speakers 

off, you can adjust your TV’s volume so that the SB 30 system will always supply most 

of the sound:

1.  Using the volume buttons on your TV, turn its volume all the way down.
2.  Then use the soundbar’s Volume Up/Down buttons to set the sound to a comfortable 

listening level.

Press the Source button on the soundbar or the remote control to switch among the three 

sources: optical digital, coaxial digital and analog.

Your soundbar incorporates extremely sophisticated digital signal processing that, along 

with 13 individual transducers powered by 11 amplifier channels, creates an astonishingly 

realistic surround-sound presentation in any size room, for listeners at any position in the 

room, without needing any extra speakers or wires.
Press the Surround Mode button on the soundbar or the remote control to switch among 

the three surround modes: Stereo, Virtual and HARMAN Wave.
