Positioning the speakers
For the best possible surround sound, all the
speakers other than the subwoofer should be the
same distance from the listening position (A).
However, this system allows you to place the
center speaker up to 1.6 meters closer (B) and
the surround speakers up to 4.6 meters closer
(C) to the listening position.
The front speakers can be placed from 1.0 to
7.0 meters (A) from the listening position.
Place speakers as illustrated below
Note
Do not place the center and surround speakers farther
away from the listening position than the front
speakers.
About magnetically shielded
speakers (to prevent color
irregularity occurring on the TV
screen)
The subwoofer in this system is magnetically
shielded to prevent magnetic leakage. However,
some leakage may occur, as a high-strength
magnet is employed. If the subwoofer is used
with a CRT-based TV or projector, install the
subwoofer at least 0.3 meter from the TV set. If
it is installed too close, color irregularity may
occur on the screen. If color irregularity occurs,
turn off the TV set once, then turn it on after 15
to 30 minutes. If color irregularity occurs again,
place the subwoofer farther away from the TV
set. If color irregularity still occurs after
performing the above, make sure that no
magnetic object is placed near the subwoofer.
Color irregularity may occur as a result of
interaction between the subwoofer and the
magnetic object.
Examples of possible sources of magnetic
interference include: magnetic latches on a TV
stand, etc., healthcare devices, toys, etc.
Specifying the speaker
parameters
To obtain the best possible surround sound, first
specify the distance of the speakers from your
listening position, then set the level and balance.
Use the test tone to adjust the speaker level and
balance to the same level.
Select [SPEAKER SETUP] in the setup display.
For details, see “Setting for the Speakers”
(page 67).
