SETTING UP YOUR F/X
WIRELESS SURROUND
(continued)
For most home theater receivers and processors,
“Distance” settings govern channel delay for op-
timal performance from Dolby Digital 5.1 and 7.1
sources. For the F/X Wireless Surround, you
need to determine the actual distance from the
listening area to the loudspeaker cabinet and
from the loudspeaker cabinet to the side walls.
Consult your receiver/processor owners manual
for proper distance setting procedures.
For Symmetrical Rooms
For symmetrical rooms, whereby the distance
between the loudspeaker cabinet and major
reflecting surfaces (side walls, or large pieces of
furniture) are approximately equal, the distance
setting for the Surround channels appears in
Table 1 (below).
The distance setting for Surround Back
channels should simply match the actual
distance of the loudspeaker behind the
listening area (“D” in figure 1).
Example:
Table 1 shows that Surround Left and
Surround Right delay should be set to 30 feet
for a 20 foot wide symmetrical room when the
F/X Wireless Surround is placed 2 feet behind
the listening area.

Table 1: Symmetrical Room: Surround Right
and Surround Left Speaker Distance
NOTE:
If your room’s dimensions and loudspeaker placement falls between or beyond the room width
and/or placement distance values in Tables 1 or 2, then you may interpolate from the tables accordingly.
NOTE:
Some home theater receivers require setting speaker delay in milliseconds rather than speaker
distance in feet. If you have such a receiver, you may read the values in Tables 1 and 2 as time delay
in milliseconds.
