x AUDIO DRC

You can compress the dynamic range of the 
sound track. This may be useful when you 
want to watch movies at low volumes.
AUDIO DRC only applies to Dolby Digital 
sources.
• DRC OFF: Does not compress dynamic 

range.

• DRC STD: Compress dynamic range as 

intended by the recording engineer.

• DRC MAX: Compress dynamic range 

dramatically.

Audio dynamic range compression lets you 
compress the dynamic range of the soundtrack based 
on the dynamic range information included in the 
Dolby Digital signal. 
“DRC STD” is the standard setting, but it only 
enacts light compression. Therefore, we recommend 
using the “DRC MAX” setting. This greatly 
compresses the dynamic range and lets you view 
movies late at night at low volumes. Unlike analog 
limiters, the levels are predetermined and provide a 
very natural compression.

You can adjust the tonal quality (bass/treble 
level) of the front speakers.
