Changing the delay time of the speakers

Effective when playing multi-channel audio
(Center and surround speakers only)
For optimum listening with 5.1-channel sound, all the
speakers, except for the subwoofer, should be the
same distance from the seating position. If you have
to place the center or surround speakers closer to the
seating position, adjust the delay time to make up for
the difference.
If either distance a or b is less than c, fi nd the difference in the table and change to the recommended
setting.
