Center Channel Delay Setting
The Center channel has its own delay which can be set from 0 to 5 ms (milliseconds) in one
millisecond increments and is active for either AC-3 or Pro Logic. This will permit you to
perfectly balance the center channel with respect to the front right and left channels so that
the intended sound arrives at the primary seating position at the same time.
While the center channel will typi-
cally appear to be the same dis-
tance to the seating area as the
front right and left speakers, this
may not be the case. As the front
right and left speakers are out-
board, they are usually slightly fur-
ther away from the seating area
than the center channel. You can
use a tape measure to determine
the distance to either front right or
front left speakers and then mea-
sure the distance to center chan-
nel. Typically, the difference will be
less than five feet and the SSD-66
(5.1) can compensate for this dif-
ference. For each linear foot the
front right and left speakers are fur-
ther away from the seating area
than the center channel, adjust the
Center Channel delay 1 ms (milli-
second).
Example
If the distance of the front speakers to the seating area is 15 feet and the center channel's
distance to the seating area is 12 feet, set the Center Channel delay to 3 ms (15 ft. - 12 ft. = 3
ft = 3 ms).
To adjust the delay times for the center channel:
1
Press the MODE button until the SSD-66 (5.1) display indicates either "PRO LOGIC"
or "AC-3".
2
Press the DELAY button until it is lit.
3
Repeatedly press the CENTER button until the display reads the appropriate rear
channel delay settings. As you press the CENTER button, the display will advance
in 1 ms increments until 5 ms is reached. It will then begin at 0 ms.

Press the DELAY button again to exit this setup mode.
