SET MENU
13 SP DELAY TIME
Use this feature to adjust the delay of the center channel
sound. This feature works when this unit decodes a Dolby
Digital or DTS signal. Ideally, the center speaker should
be the same distance from the listening position as the left
and right main speakers. However, in most home
situations, the center speaker is placed in line with the
main speakers. By delaying the sound from the center
speaker, the apparent distance from the center speaker to
the listening position can be adjusted to make it seem the
same as the distance between the left and right main
speakers to the listening position. Adjusting the delay
time for the center speaker is especially important for
giving depth to the dialog.
Control range (ms): 0 to 5
