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.

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.

200Hz

Cutoff

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.

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

180°

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.
