Installation
Connecting speakers
The unit allows you to use 6.1 channel system.
The ideal surround speaker system for this unit is 6-
speaker systems, using front left and right speakers, a
center speaker, surround left and right speakers,
surround center speaker, and a subwoofer.
You can enjoy high fidelity reproduction of DVD
software recorded in the Surround EX format if you
connect the surround center speaker (6.1 channel).
For best results we recommend that all front speakers
be of the same type, with identical or similar driver
units. This the action moves from side to side.
Your center channel speaker is very important as over
80 % of the dialog from a typical motion picture
emanates from the center channel. It should possess
similar sonic characteristics to the main speakers.
Surround channel speakers need not be identical to
the front channel speakers, but they should be of high
quality.
The surround center speaker is useful for playback of
Dolby Digital Surround EX or DTS-ES. One of the
benefits of both Dolby Digital and DTS is that
surround channels are discrete full range, while they
were frequency limited in earlier "Pro Logic" type
systems.
Bass effects are an important part of home theater.
For optimal enjoyment a subwoofer should be used as
it is optimized for low frequency reproduction.
Example of 6.1 channel speaker
system configuration
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.
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 equidistant from the listener.
Surround center speaker
Surround center speaker is required when a full 6.1-
channel system is installed.
This speaker is necessary to enjoy Dolby Digital EX,
DTS-ES Matrix, and DTS-ES Discrete. They enhance
the realism of surround sound and improve sound
localization behind the listener. Position them
behind the listener about 2–3 feet (60–100 cm) above
ear level.
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 position, the shape of
your listening room, and your listening position. In
general, a good bass sound can be obtained by
installing the subwoofer as shown left.
Tip
To find the best position for your subwoofer, while
playing a movie or some music with good bass,
experiment by placing your subwoofer at various
positions within the room, and choose the one that
provides the most satisfying results. 0
