Speaker Delays
Like the Levels submenu(s), the Delays submenu(s) are interactive. Only installed DAC channels will appear in the
Delays submenu. If there are two Delays submenus, the
A-D
button will toggle between them.
The Delays submenu allows the user to set a time delay for each speaker to reflect the audio system configuration, room
characteristics, or the listener’s preference. The sound from all speakers should reach the listening position at the same
time, and this submenu provides a means for achieving just that. The allowable range for the all speakers and
subwoofers is 0 to 50 mS.

Press
SETUP
, input (
INP
) then delays (
DLYS
) to access the speaker delays setup submenu shown in figure 37. The
current delay settings will be displayed on the top row of the VFD. The submenu title “
DELAYS
” will be displayed in the
upper right corner. Delay settings apply to all
MODES
, however, they can be further manipulated when the
MODE
is
Dolby Digital or DTS, via additional Setup submenus for these
MODES
. These additional Setup features and respective
submenus are discussed further in this section.
The first time a multi-channel audio system is set up in a room, calibration of time delay [and speaker levels] is required
in order to have the sound from each individual speaker reach the listener at the correct time.
If more than six DAC channels are installed in the Casablanca IV, there will be a right arrow above the
A-D
button. Press
this button, and the second Delay page will be presented as shown in figure 38.

DELAYS 2 Submenu
Speaker delay is required if a speaker is closer to the listening position than the front left and right speakers. When this
is the case, the delay time should be 1mS for each foot difference.
Begin by measuring the distance (in feet) from each speaker to the listening position. Write down all of these values.
Enter the difference in feet from the primary listening position to each speaker and subwoofer.
Note
: It is no longer necessary to subtract one speaker distance from another to determine the closest speaker. This is
now done automatically inside the Casablanca IV’s DSP section.
