Delay time of center speaker
When playing a DVD recorded with Dolby Digital audio, the distances from the listening position to the
center and surround speakers should ideally be identical to those of all other speakers except for the
subwoofer. The delay time setting makes it possible to compensate for the difference in distances of actual
speakers by delaying the audio output from the center speaker and surround speakers so that the sounds
from all speakers reach the listening position at the same timing. (The delay time adjustment is available
only with Dolby Digital.)
Before starting the speaker setting, see the following figure and measure distance A of the center speaker
(A = Df - Dc) and distance B for the surround speakers (B = Df - Ds). The standard delay time settings can
be identified based on these values and the following tables.
