number is read into Casablanca III’s main computer and the Casablanca III’s analog volume controls are
properly adjusted. This is the best-sounding and preferred setting.
DIGI
: Dialog normalization will be performed in the digital domain. Digital reduction of volume results in a loss
of resolution i.e. a 16 bit source can effectively be reduced to 15 bits or worse.

Press the
A-D
button to access Page 2 of the Dolby Digital set up submenu, which is shown in figure 45.

DOLBY DIGITAL Page 2 Sub Menu
This submenu allows the user to adjust the center, individual surround speaker delays and levels and
LFE
when the
MODE
is Dolby Digital only. When the Mode is anything other than Dolby Digital, all settings in this sub menu will
have no effect.
It is important to note that the level and delay settings in this sub menu are interactive, or relative to those in the main
SETUP
/
INP
/
LEVELS
and
SETUP
/
INP
/
DELAYS
submenus. In other words values in this sub menu are added to, or
subtracted from those values in the
SETUP
/
INP
/
LEVELS
and
SETUP
/
INP
/
DELAYS
submenus. For example: if the
center level (
CLVL
) in this sub menu is set to
–2
and the center level in the
SETUP
/
INP
/
LEVELS
submenu were set to
+3
, the overall center level, when the
MODE
for the currently selected input is Dolby Digital, would be
+1
. This same
process applies to the delays. However, the Casablanca III does not support negative delays based on the theory that
even we at Theta cannot make time go backwards. Therefore, as an example, if the center delay in the
SETUP
/
INP
/
DELAYS
submenu were set at
0
and in this Dolby Digital setup submenu, set at
–1
, the overall center
delay would be
0
.
Note
: If the incoming signal is Dolby 2.0 with a surround indication bit set at surround, and the
2CHEN
mode set to
Circle the delay settings in the
DELAYS
sub menu are interactive with the ones in the
CIRCLE SURROUND
setup
submenu and not with those in the
DOLBY DIGITAL
setup submenu.
In this submenu, button #
1
offsets the center speaker’s delay [from the
SETUP/INP/DELAYS
] when the
MODE
is set
to Dolby Digital, button #
2
offsets the center level, button #
3
offsets the surround left/right, sides and center surround
delay and button #
4
offsets the surround left/right, sides and center surround level.
Button #
5
controls the
LFE
gain setting for Dolby Digital sources. Dolby Digital sources usually contain an LFE (low
frequency effects) channel. This channel commonly contains sound effects such as explosions, but may also contain
soundtrack information. Casablanca III offers the user an
LFE
range of between
0
and
-30
for this setting, as well as
OFF
.
OFF or 0
may be useful for late night viewing or if there isn't a subwoofer / speaker capable of handling the low
frequencies contained in the LFE channel.
0
dB, the preferred setting, maintains the
LFE
setting in proper proportion
to the remaining five discrete channels. Any other setting lowers the normal
LFE
level, in dB, by the value set.
When all settings are made, press the
SETUP
button 3 times returns the user to the
INPUT SELECT
menu.
