APPENDIX : DOLBY VOLUME/DRC SET continued
I
Dd VOL HIGH 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.
DYN RANGE MEDIUM 1
Compression) is ON resulting in medium dynamic range (moderate compression)
DYN RANGE LOW 2
compression).
DRC AUTO(THD,DTSHD) – Dolby Volume is OFF, DRC is ON, high compression conditional upon
the presence of DYNF flag in the digital source stream.
3. Additional configuration options for Dolby Volume.
When any of the Dolby Volume selection is made, that is if line 2 selects anything from Dd VOL LOW FULL
MODE to Dd VOL HIGH HALF MODE (and only those) then the additional configuration settings are
displayed in the lines 3 and 4 on the screen:
Line 3: Dd VOL OFFS 0.0dB - use volume knob to adjust Dolby Volume level offset –20.0..+20.0dB. This
parameter defines the maximum sound level for the recording (as it should have been listened to
originally, in a studio etc). For example, when listening to a movie, this value could be increased
initially during the loudest portion of the recording, to set the reference for the loudest parts. A positive
VOL OFFS value makes the average output sound less loud, negative value makes it louder.
Note: Dd VOL OFFS does NOT have to be continously adjusted during a playback; this is an
optional once-off (per movie) adjustment!
Line 4: Dd VOL MID/SIDE OFF – use volume knob or SURROUND left/right arrow to toggle this parameter
ON or OFF. MID/SIDE is relevant only in STEREO mode and causes Dolby Volume algorithm to
automatically re-balance the left and right channels. Default is OFF.
Dolby Volume algorithm is operating only at lower sample rates <=48kHz. It is automatically disabled above
48kHz but this is not indicated on screen!
No configuration settings are available for DRC selections.

This is equivalent to DYNAMIC RANGE MEDIUM selection in SP1.7, SP2

This is equivalent to DYNAMIC RANGE LOW selection in SP1.7, SP2

+6dB is often sufficient to adjust the loudest movie scenes down to a comfortable level.

– Dolby Volume is OFF, DRC is ON producing low dynamic range (high
