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 TGIII has two side-axis chan-
nels which 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).
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.
The Surround speak ers
Place each surround speaker to
be 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 soundfi 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 fl e c 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 TGIII has two extra outputs for
surround back speakers. These create
a wonderful sense of realism in sur-
round effects during playback of Dolby
Digital EX and DTS ES.
The TGIII can be confi gured for one
or two surround back speakers. Ide-
ally, all the surround speakers should
be of the same make and model, and
fi tted at similar heights to produce a
smooth continuous soundfi eld.
If you are connecting one surround
back speaker, connect its amplifi er
input to the TGIII left surround back
output. Place the speaker behind your
listening position.
Subwoofer Location
The TGIII has identical output con-
nections for up to three subwoofers, in
addition to a fourth, balanced sub out.
The best location for a single
subwoofer can be found by playing
some heavy bass and proceeding as
follows:
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.
