APPENDIX I: DOLBY VOLUME/DRC SET continued
SP3 Dolby Volume/DRC Screen Page 2 of 3
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 moderately reduced). The “Half Mode” means
that Dolby Volume algorithm applies only audio compression but
not spectral equalization.
DYN RANGE MEDIUM 1
3
– Dolby Volume is OFF but older DRC algorithm
(Dynamic Range Compression) is ON resulting in medium
dynamic range (moderate compression)
DYN RANGE LOW 2
4
– Dolby Volume is OFF, DRC is ON producing low
dynamic range (high 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
3
This is equivalent to DYNAMIC RANGE MEDIUM selection in SP1.7, SP2
4
This is equivalent to DYNAMIC RANGE LOW selection in SP1.7, SP2
