ANLG : Dialog normalization will be applied in the analog domain. 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
significant loss of resolution.

This submenu allows the user to adjust the center, side and surround speaker delays and levels, LFE level and
processing for additional speakers when the MODE is Dolby Digital.
It is important to note that the level and delay settings in this submenu are added to or subtracted from those in the
main
SETUP / INP / LEVELS and SETUP / INP / DELAYS submenus. For example: if the center level ( CLVL ) in this
submenu 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.
It is important to note that the Casablanca III HD does not support negative delays based on the theory that even we at
Theta cannot make time go backwards. Therefore the sum of the delays cannot be less than
0 . As an example, if the
center delay in the SETUP / INP / DELAYS submenu were set at 0 and in the Dolby Digital setup submenu set at –1 , the
overall center delay would be 0 .
In this submenu: button # 1 offsets the center speaker’s delay [from the SETUP/INP/DELAYS ]; 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 containing an LFE (low frequency effects) channel.
i.e. 5.1, 6.1 or 7.1 signals. This channel commonly contains sound effects such as explosions, but may also contain
soundtrack information. Casablanca III HD offers the user an
LFE range of between OFF and -30 for this setting.
OFF 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.
If the incoming signal is Dolby Digital 5.1, and the user desires to create sides or a center surround channel, use the
+SPKR (or Additional Speakers) parameter to indicate which MODE will be used to create them. There are a limited
amount of modes that can do this. They are displayed in Table 6.
