DOLBY DIGITAL Page 2 Sub Menu

This submenu allows the user to adjust the center, individual surround speaker delays and levels and

when the

It is important to note that the level and delay settings in this sub menu are interactive, or relative to those in the main

submenus. In other words values in this sub menu are added to, or

submenus. For example: if the

center level (

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

for this setting, as well as
