2 LFE LEVEL

(low-frequency effect) channel when playing back a
Dolby Digital or DTS signal. The LFE signal carries the
low-frequency special effect sound which is only added to
certain scenes.

3 SP DLY TIME (speaker delay
time)
Use this feature to adjust the delay of the center and the
rear center channel sounds. This feature works when there
is sound output from the center speakers, with a source
like Dolby Digital or DTS, etc. Ideally, the center speaker
and the rear center speaker should be the same distance
from the main listening position as the left and right
speakers. However, in most home situations, the center
speaker or the rear center speaker are placed in line with
the main speakers or the rear speakers. By delaying the
sound from the center speaker and the rear center speaker,
the apparent distance from the center speaker and the rear
center speaker to the main listening position can be
adjusted to make it seem the same as the distance
between the main left and right speaker, and the rear left
and right speakers to the listening position. Adjusting the
delay time for the center speaker is especially important
for giving depth to the dialogue.
Control range:
CENTER........................... 0 to 5 ms
REAR CNTR (center)......0 to 30 ms
Initial setting:
CENTER............................0 ms
REAR CNTR (center)...... 3 ms
H~Pr^s < / > to increase or decrease the delay
of the center and the rear center channel
sounds.

about 30 cm (one foot) farther away from the listening
position.
