Specifying speaker distances
To get the best from surround sound, it's important that the sound
from each speaker reaches the listener at the same time. To achieve
this, you need to specify the distance from each speaker to the
listening position.
1. Measure and make a note of the distance from
each speaker to the listening position.
2. Press the SPEAKER ADJUST three times.
"Distance Setup" then "Front:" are displayed. Use the
DISPLAY button to select meters or feet.
To select other speakers, press SPEAKER ADJUST again.

You can specify speaker distances of between 1 and 30 ft. in 1
ft. steps (0.3 and 9 m in 0.3 m steps). However, the Front
Distance limits the Distance of other speakers. The Center
Distance and Subwoofer Distance must be within plus or minus
5 ft (1.5 m). of the Front Distance. The Surround Right
Distance and Surround Left Distance must be no less than
–15 ft (–4.5 m). or no more than +5 ft (+1.5 m). of the Front
Distance. For example, if the Front Distance is set to 20 ft
(6 m)., you must set the Distance of other speakers as follows:
Center Distance, Subwoofer Distance: 15 to 25 ft (4.5 to 7.5 m).
Surround Right Distance, Surround Left Distance: 5 to 25 ft
(1.5 to 7.5 m).
