APPENDIX
In some systems, two center speak-
ers are used; one on either side of the
TV. As they are in mono, the result
is a sound image that is po si tioned
exactly at the screen center.
Side-Axis Speakers
The Receiver's Aux speaker outputs
can be conÞ gured as two side-axis
channels, or you can use an external
power ampliÞ er connected to the line-
level side-axis outputs. The side-axis
signals are matrixed from the left
and right front channels, so they are
available in stereo as well as surround
modes.
Use the OSD SPEAKER SIZE
menu to turn the side-axis channels
on or off (see page 38). If you want
the Receiver's Aux outputs to power
the side-axis speakers, conÞ gure the
Aux outputs from the AMPLIFIER
OSD Menu, see page 41. This menu
allows you to set the Aux channels to
be either surround back, side-axis or
Zone 2 outputs.
D Shows the typical placement
of the side-axis speakers. You
can also angle them in towards
your listening position. Place
the speakers along the side
walls, close to the fronts.
Surround Speak ers
Place each surround speaker an
equal distance away from your central
lis ten ing position, and keep them at
least one or two feet above ear level.
A The diagram shows the use
of dipole surround speakers.
These are usually positioned
to the side of your listening
position. They radiate forwards
and back wards and have a
quiet null zone which should
point towards the lis ten er. The
overall effect is that you cannot
hear the direct sound from the
surround speakers, just the
average soundÞ eld.
Conventional surround speakers
can be placed behind the listener, on
the rear walls or the side walls. Adjust
the angle so they do not point directly
at the listener but cause re ß ec tions
from the sidewalls or the ceiling. This
will give the effect of broadening the
rear sound stage so that you cannot
dis tin guish the sound as coming from
a small box on the wall but from a
larger area behind you.
Surround Back Speakers
The Receiver's Aux outputs can be
conÞ gured as surround back outputs,
or you can use an external power
ampliÞ er connected to the line-level
surround back outputs. The surround
back speakers create a wonderful
sense of realism in surround effects
during playback of Dolby Digital EX
and DTS ES.
Use the SPEAKER SIZE OSD
Menu to turn the surround back chan-
nels on or off (see page 38). If you
want the Receiver's Aux outputs to
power the surround back speakers,
conÞ gure the Aux outputs from the
AMPLIFIER OSD Menu, see page 41.
The Receiver can be conÞ gured
for one or two surround back speak-
ers. Ideally, all the surround speak-
ers should be of the same make and
model, and Þ tted at similar heights to
produce a smooth continuous sound-
Þ eld.
If you are connecting one surround
back speaker, use the Receiver's
left surround back output. Place the
speaker behind your listening position.
Subwoofer location
The Receiver has identical line-lev-
el output connections for up to three
powered subwoofers.
To Þ nd the best location in your
room to place a subwoofer:
1. Place the subwoofer right
on the seat of your couch or
listening easy chair.
2. You can then either run the
calibration (noise) signal
through it, or simply plug the
analog outputs of a CD player
directly into your subwoofer’s
low-level inputs. Turn down
the subwoofer's volume level
before turning on the CD, then
play some of your favorite mu-
sic samples with heavy bass.
3. Walk around the room, stand-
ing in all the positions where
you might be able to place
the subwoofer. This is usually
somewhere close to the cor-
ners of the room. Try locations
fairly close to the front speak-
ers.
4. Notice where in the room
the bass output from the
subwoofer sounds the loudest.
Shut things down and install
the subwoofer there.
5. This is the best position for the
sub woof er. The bass will sound
the best when you are sitting in
your normal lis ten ing position.
