Connecting Speakers
Enjoying Home Theater
You can use two sets of speakers with the HT-R820THX: speaker set A and speaker set B.
Speaker set A (HTP-820) should be installed in your main listening room and can be used with THX, Dolby Digital
and DTS surround material.
Speaker set B can be installed in another room and used with stereo and mono material. Speakers can be positioned in
the standard position for stereo speakers or however you like.
Front left and right speakers
These output the overall sound. Their role in a home theater is to provide a solid
anchor for the sound image. They should be positioned facing the listener at
about ear level, and equidistant from the TV. Angle them inward so as to create
a triangle, with the listener at the apex.
Center speaker
This speaker enhances the front left
and right speakers, making sound
movements distinct and providing a
full sound image. In movies it's used
mainly for dialog.
Position it close to your TV (preferably
on top) facing forward at about ear
level, or at the same height as the
front left and right speakers.
Subwoofer
The subwoofer handles the bass sounds of
the LFE (Low-Frequency Effects) channel.
The volume and quality of the bass output
from your subwoofer will depend on its posi-
tion, the shape of your listening room, and
your listening position. In
general, a good bass sound
can be obtained by install-
ing the subwoofer in a front
corner, or at one-third the
width of the wall, as shown.
If the subwoofer is situated
close to a wall, rack, etc.,
leave a gap of at least 6
inches (15 cm).

Speaker Configuration
To get the very best from your surround-sound system, you should also specify the distance between the listener and
each individual speaker so that the sound from each speaker arrives at the listener's ears at the same time (see page 48).
In addition, you should set the level of each individual speaker to achieve an equal balance (see page 49.)

Surround back speaker
This speaker further enhances
the realism of surround sound
and improves sound localiza-
tion behind the listener. Posi-
tion it behind the listener about
2–3 feet (60–100 cm) above
ear level. Make sure that the
listening position is within the
range of the speaker.
Surround left and right speakers
These speakers are used for precise sound
positioning and to add realistic ambience.
Position them at the sides of the listener, or
slightly behind, about 2–3 feet (60–100 cm)
above ear level. Ideally they should be equi-
distant from the listener.
Corner
Wall-mounting the surround speakers
If the surround speakers are to be wall-
mounted, make sure that the walls are
strong enough to support the speaker's
weight. The weight that mounting screws
can support varies greatly depending on the
wall material and the position of the reinforc-
ing ribs embedded in the wall.
Use long screws with a head diameter of
1/4 inch (6.3 mm) or less and a shank diam-
eter of 1/8 inch (3.5 mm) or less. (We rec-
ommend that you consult a home
installation professional.)
