Sony STR-DE915 - Manual (Page 8)

Getting Started
Speaker placement for STR-DE915
For the best possible surround sound, we recommend:
• The best quality speakers possible
• Front, center, and rear speakers of equivalent size
and quality
• Positioning of speakers at the same distance from the
listening position (O).
The center speaker, however, may be moved closer,
but not beyond the straight line connecting the two
•front speakers (©). The rear speakers may also be
closer to listening position than the front speakers (©),
to suit the configuration of your room. If the surround
effect is still inadequate, adjust the CENTER DELAY
and REAR DELAY parameters (see page 19),
Notes
• Do not place the center or rear speakers farther away from
the listeningy>osition than the front speakers.
• When mounting the rear speakers on side walls
perpendicular to the listening position they should be
placed 60 - 90 cm.above the listening position (as shown
below in "Speaker placement for STR-DE715/DE615/
D660Z/D560Z").
Depending on the shape of your room (etc.), you may
wish to place the rear speakers behind you instead of
on the side walls. One advantage of this placement is
that you can use a pair of large floor standing speakers
matching your front speakers.
Note
If you place the rear speakers behind you, be sure to
check the speaker location setting in the SPEAKER
SETUP menu when using VIRTUAL MULTI REAR
and VIRTUAL REAR SHIFT sound fields (see pages 19
and 24 for details).
