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 positioned
exactly at the screen center.
Surround Speakers
Place each surround speaker to
be an equal distance away from your
central listening position, and keep
them at least one or two feet above
ear level.
A The diagram on the previous
page shows the use of bipole
or dipole surround speakers.
These are usually positioned to
the side of your listening posi-
tion.
B and C 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 di-
rectly at the listener but cause
reflections from the sidewalls
or the ceiling. This will give
the effect of broadening the
rear soundstage so that you
cannot distinguish the sound
as coming from a small box on
the wall but from a larger area
behind you.
LS1/LS2 OPTIONS
Two sets of binding posts and line
out jacks are available for surround
speakers and can be toggled in the
setup menu. If you have bipole sur-
round speakers for movies and direct
fire surround speakers for music, you
can wire both pairs up and switch
between them in your setup menus.
Surround Back Speakers
The TGR-401 has two extra outputs
for surround back speakers. These
create a wonderful sense of realism
in surround effects during playback of
Dolby Digital EX, Dolby Pro Logic IIx,
and DTS ES.
The TGR-401 can be configured
for one or two surround back speak-
ers. Ideally, all the surround speak-
ers should be of the same make and
model, and fitted at similar heights to
produce a smooth continuous sound-
field.
If you are connecting one surround
back speaker, connect its amplifier in-
put to the TGR-401 left surround back
output. Place the speaker directly
behind your listening position.
Note that the surround back output
posts are inactive if Zone 2 speakers
are powered by the TGR-401.
Subwoofer Location
The TGR-401 has one output con-
nections for a powered subwoofer.
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
subwoofer. The bass will sound
the best when you are sitting in
your normal listening position.
