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 and right speakers. Subtract the front left
and surround left distance from the front right and the surround right distance.
Add this number to the existing delay value of the surround left/right speakers. (1
mS/foot). The chart in figure 35 can also be used to calculate the surround
left/right delay values.
Figure 35 - 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. Add this value 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 the properties of low frequencies, 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, press the applicable INPUT SELECT button, SETUP / INP (input) then button # 4 ( MODE ).
See figure 16 on page 50. 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. Changing modes via the MODE button does not store a mode selection.
VFD Brightness
Each INPUT SELECT button can have a different VFD brightness assigned to it. Pressing button # 6 in figure 15
(page 50) allows the user to change the default brightness to OFF, ¼, ½, ¾ or FULL brightness. Changes to this
parameter are reflected the next time that INPUT SELECT button is pressed. If this value is set to OFF , pressing any
button except DISPLAY will automatically brighten the VFD to the maximum level. If the button pressed is not another
INPUT SELECT or function button, then the VFD will revert back to its default brightness in X seconds. X represents
the TIME parameter value in the SETUP / INP Page 1 / submenu. If the VFD is on but not set to FULL , it will remain at
the default brightness until a different INPUT SELECT button is selected. The DISPLAY button will override the
default VFD brightness setting. The Display Time feature takes precedent over the VFD brightness parameter. See
details regarding the Display Time parameter on page 79.
