ADJUSTING THE AUDIO SETTINGS
To adjust the audio settings:
1.  Press the 
MENU button on the 
remote. The on-screen menu  
is displayed.
2.  Use the 
Arrow buttons on the 
remote to highlight 
Audio and 
press 
OK. The AUDIO menu  
is displayed.

Arrow buttons to 
highlight the setting you wish 
to adjust, then press 
Left/
Right Arrow buttons to change  
the setting:
•  TV Speakers - Turns the 
built-in speakers on or off.
•  Surround Sound - Surround sound uses DTS TruSurround
 
to deliver an immersive surround sound experience from 
the TV’s internal speakers. TruSurround completes the 
entertainment experience by providing deep, rich bass and 
by delivering crisp details and clear, intelligible dialog. Select 
On or Off.
•  Volume Leveling - Volume leveling uses DTS TruVolume
 
to maintain consistent volume levels during transitions 
between program content, AV formats, and input sources. 
Select 
On or Off. In a few cases, volume leveling may 
artificially  suppress  volume  increases,  making  it  difficult  to 
hear dialog or flattening sudden noises. If this occurs, turn 
volume leveling off.
•  Balance - Adjusts the loudness of the audio output from the 
left and right speakers.
