DOLBY VOLUME/DRC
Dolby® Volume is an advanced digital signal processing technology for controlling playback volume. It evens out the volume level on everything you
watch, greatly improving your listening experience. No more sudden blasts from ads, no dialogue suddenly too soft, no volume differences when you
change channels or switch sources.
BRINGING UP THE DOLBY VOLUME SCREEN:
Pressing a down arrow key while the default (idle) screen is being
displayed brings up the Dolby Volume screen for a about 10 seconds.
After 10 seconds the screen reverts back to default (or when the up or
left arrow is pressed).
The screen shows only one active parameter selection line: Line 2: DYN
RANGE FULL OFF This setting (power up default) indicates that the
dynamic range is full, in other words - no dynamic range compression is
engaged (DRC=OFF). A selection made using this screen will remain
persistent after the screen times-out back to the default display. The
Dolby Volume/DRC selection will persist for as long as the source is not
switched over (for example from BLU-RAY to CBL/SAT etc) and as long
as the unit is not powered off or placed into standby.
DOLBY VOLUME MODES
Turning a volume control knob or pressing the SURROUND MODE left
and right arrow keys causes the following selections to scroll in line 2:
DYN RANGE FULL OFF - all dynamic range compression is off
(power up default) and Dolby Volume is OFF
DD VOL LOW FULL MODE - Dolby Volume is ON in low strength,
and the audio dynamic range is slightly reduced.
The ―Full Mode‖ (as
opposed to ―Half Mode‖) means that Dolby Volume algorithm applies
both audio compression and spectral equalization.
DD VOL MED FULL MODE - Dolby Volume is ON, medium strength
(dynamic range is moderately reduced). The ―Full Mode‖ means that
Dolby Volume algorithm applies both audio compression and
spectral equalization.
DD VOL HIGH FULL MODE - Dolby Volume is ON, high strength
(dynamic range is highly reduced). The ―Full Mode‖ means that
Dolby Volume algorithm applies both audio compression and
spectral equalization.
DD VOL LOW HALF MODE - Dolby Volume is ON, low strength
(dynamic range is slightly reduced). The ―Half Mode‖ (as opposed to
―Full Mode‖) means that Dolby Volume algorithm applies only audio
compression but not spectral equalization.
DD VOL MED HALF MODE - Dolby Volume is ON, medium strength
(dynamic range is moderately reduced). The ―Half Mode‖ means that
Dolby Volume algorithm applies only audio compression but not
spectral equalization.
DD VOL HIGH HALF MODE - Dolby Volume is ON, medium
strength (dynamic range is moderatel
y reduced). The ―Half Mode‖
means that Dolby Volume algorithm applies only audio compression
but not spectral equalization.
DYN RANGE MEDIUM 1 – Dolby Volume is OFF but older DRC
algorithm (Dynamic Range Compression) is ON resulting in medium
dynamic range (moderate compression)
DYN RANGE LOW 2 – Dolby Volume is OFF, DRC is ON producing
low dynamic range (high compression).
DRC AUTO – Dolby Volume is OFF, DRC is ON, high compression
conditional upon the presence of DYNF flag in the digital source
stream.
