Basic positioning example and the role of each speaker
Although recommended speaker positions vary depending on the room size and wall material,
this section offers a basic positioning example and explains the function of each speaker.
Even if you cannot precisely follow the example below, you can still enjoy optimal surround sound
by specifying the distance from the listener to the speakers (page 76). You can also adjust the vol-
ume level of each speaker to suit your preference (page 77). (Make these settings after all con-
nections are completed.)
Using optional speaker stands or brackets
Each satellite speaker has one M5 screw hole on
the back, and two 60 mm M5 screw holes on the
bottom. To secure the bottom surface, use optional
stands or brackets.
If you use a stand or brackets, use M5 screws with
an effective screw length of 7–12 mm, depending
on the thickness of the stand.
Center speaker
Place the center speaker as close as possible to the screen and position it so that the sound is
directed at the listener’s ears.
The center speaker enriches the sound image by framing the sound effects and panning sound
output from the left and right front speakers. In movies, generally, dialog and narration are output
from this speaker.
Left and right front speakers
Place the front speakers in front of the listener.
•Position the speakers at the same height as the center speaker.
•Position the speakers so that the audio will be directed at the listener’s ears. It is recommended
that you place the speakers symmetrically.
Surround speakers
Place the surround speakers to the sides or rear of the listener.
The surround speakers enhance the atmosphere of theaters or halls by conveying the three-
dimensional movement of sound and re-producing environmental sounds (that represent the
background) and special effect sounds (for example, that bring a scene to a climax).
Subwoofer
Place the subwoofer near the front speakers.
The subwoofer has a great advantage in producing powerful, super bass effects. Only low-range
sound is output.
Caution:
Do not place the satellite speakers on the edge of a desk or rack. Otherwise, they may fall, caus-
ing injury.
