decoding for 2 channel audio sources.
This system can reproduce 2 channel sound in 4
channels through Dolby Pro Logic; or 5

Making the low-level sound
clear (DOLBY DRC)
When you listen to DVDs at low volume levels,
you can compress the dynamic range and finely
adjust for low-level sound. This function works
only for DVDs compatible with Dolby DRC*
(audio DRC).
* Dolby DRC: Dolby Dynamic Range
Compressor
1
Press MAIN MENU repeatedly to select
“LEVEL”.
2
Move the V/v/B/b button up or down
to select “DRC”.
3
Move the V/v/B/b button to left or
right to select “STD” or “MAX”.
If you select “STD”, the dynamic range is
compressed as intended by the recording
engineer.
If you select “MAX”, the dynamic range is
compressed dramatically.
To turn off the DOLBY DRC, select
“OFF”.
Tip
Dynamic range compressor lets you compress the
dynamic range of the soundtrack based on the dynamic
range information included in the Dolby Digital signal.
“STD” is standard compression, but because many
sources have only light compression, we recommend
using the “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.
Note
Dynamic range compression is possible with Dolby
Digital sources only.
