Philips FR-968 - Manual (Page 14)

General hints for positioning
Avoid positioning the speakers in a corner or on the floor as
this will boost the bass tones too much. Placing the speakers
behind curtains, furniture, etc. will reduce the treble
response. The listener should always be able to ”see” the
speakers.
Each room has different acoustic characteristics and the
positioning possibilities often are limited. You can find the
best position for your speakers by referring to the picture
above.
As a minimum we recommend 5 speakers (2 front, a center,
2 surround) for good surround sound. It is possible to
reproduce some kind of surround sound with fewer speakers.
This is done by redirecting the signals which are foreseen for
the missing speakers to the existing ones. See “Menus” on
how to set up the receiver correctly for the number and size
of the speakers used.
Positioning the front speakers
The front speakers should be placed to the right and left in
front of the listening position like usual stereo speakers.
Positioning the center speaker
The center speaker should be placed in the center between
the two front speakers, e. g. underneath or on top of the TV.
The best height for the center speaker is the height of the
listener’s ears (while seated).
Positioning the surround speakers
The surround speakers should face each other and be in line
with, or slightly behind the listener.
Positioning the subwoofer
A subwoofer can be used to enhance the bass performance of
your system dramatically. The subwoofer can be positioned
anywhere in the room, because it is not possible to locate the
source of deep tones. Nevertheless, you should not place the
subwoofer in the middle of a room, since the bass could be
severely weakened. Do not place any object on the
subwoofer.
Once the number and position of loudspeakers has been
fixed, you can adjust the initial receiver settings for optimal
surround sound with the actual setup:
1 Set which speakers have been connected to the receiver
(see “Menu structure/
* SPEAKR SETUP”).
Note: The initial setting of your receiver is:
two front speakers left and right: present (cannot be
altered)
center speaker: present
two rear speakers: present
subwoofer: present.
2 Select the size of the speakers (SMALL or LARGE)
(see “Menu structure/
* SPEAKR SIZES”).
Select SMALL if your speaker is able to reproduce low notes
down to at least 80–100 Hz. Select
LARGE if your speaker
is able to reproduce low notes down to at least 50 Hz. (As a
rule of thumb, a LARGE speaker has a cone diameter of at
least 12 cms (5 inches).) See the specification sheets of your
loudspeakers.
3 Set the distance from the speakers to the listener’s position
(see “Menu structure/ * SPK DISTANCE”).
Note: If you prefer that your receiver does not correct
automatically for speaker sizes and distances, you can
re-progam it to a neutral setting by
– installing all speakers: (Subwoofer present, Center
and Rear loudspeakers: all
YES),
– setting Front, Center and Rear speaker sizes to
LARGE,
– setting all loudspeaker distances (L/R, Center and
Rear) to the same distance (e.g. 10 ft).
