should be 1mS for each foot of difference between the center and front left/right, to the listening position. If the front
left/right speakers are closer than the center, then set the center delay at 0 and
delay the front left/right speakers, again, 1mS for each foot of difference from the
listening position.
To determine a delay time for the surround left/right speakers, measure the
distance (in feet) from the listening position to the front left/right, then from the
listening position to the surround left right. Subtract the two numbers and use
this value (the difference between the front left and surround left, then the
difference between the front right and the surround right) to add to the existing
delay value of the surround left/right speakers. (1 mS/foot). The chart in figure
38 can also be used to calculate the surround left/right delay values.
Figure 38 - Rear Delay Settings
For the surround center delay, take the difference (in feet) between the center surround speaker and the listening
position and the surround left or right to the listening position. With this value, add it to the existing [default] surround
center delay value (1ms per foot of difference).
To set the side speaker delays, calculate the difference (distance in feet) between the left side and left front speakers.
Add the difference to the default value already set for the left side to give this speaker its new value.
Calculate the difference (distance in feet) between the right side and right front speakers. Add the difference to the
default value already set for the right side to give this speaker its new value.
Because of their low frequency properties, typically a delay in the subwoofer(s) is virtually undetectable. This being
the case, it may be appropriate to leave the subwoofer delay values set at 0. However, if any subwoofer is closer to
the listening position than the front left/right speakers, a delay value can be set for these subs. The delay value will be
the difference (in feet) between the sub itself and the front left or right speaker, to the listening position.
Default Mode
Each INPUT SELECT button can have a different default MODE assigned to it. To assign a default MODE for a given
INPUT SELECT button, first press the applicable INPUT SELECT button, SETUP / INP (input) then button # 4 in figure
22 on page 48 ( MODE ). Edit this parameter to select the desired default MODE , then press SETUP twice to exit.
Repeat this procedure for each INPUT SELECT button.
Note : Pressing the front panel MODE function button allows the user to audition different modes for a given source,
when applicable, however changing modes via the MODE button does not store a mode selection.
Note : The Default MODE feature allows the user to select between all modes, whether or not a mode is installed into
the Casablanca III. For example, Circle Surround may not be installed yet it is selectable in this parameter. When this
is the case, the input signal will be processed in the Mono mode, this being routed to the front center channel only.
