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.
