APPENDIX
In some systems, two center
speakers 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 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 TGIII has two extra outputs
for surround back speakers. These 
create a wonderful sense of realism 
in surround effects during playback of 
Dolby Digital EX and DTS ES.
The TGIII can be confi gured for
one or two surround back speakers. 
Ideally, all the surround speakers 
should be of the same make and 
model, and fi tted at similar heights to 
produce a smooth continuous sound-
fi eld.
If you are connecting one sur-
round back speaker, connect its am-
plifi er input to the TGIII left surround 
back output. Place the speaker behind 
your listening position.
The Subwoofer
The TGIII has identical output
connections for up to three subwoof-
ers, 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 at your
normal listening position, and 
play your music. 
2. Leaving the subwoofer in this
po si tion, walk over to a few 
likely locations in your room, 
where the subwoofer might 
fi t and fi nd a point where the 
deep bass sounds the best. 
This is usually somewhere 
close to the corners of the 
room. Try locations fairly close 
to the front speakers. 
3. When you have found the best
prac ti cal location, move your 
subwoofer to this point. 
4. This is the best position for the
sub woof er. The bass will sound 
the best when you sit in your 
normal lis ten ing position.
5. Typically, a corner location will
yield the highest subwoofer 
output
