E-18
speakers
e AVR400 allows you to connect up to seven speakers
and an active subwoofer in the main system. e output
channels correspond to speakers installed in the front
le, centre, front right, surround le, surround right,
surround back le, surround back right and an active
subwoofer.
e conguration and placement of your speakers
is very important. All speakers, with the exception of
the subwoofer, should be arranged around your normal
viewing/listening position. e subwoofer should be
placed in a position which gives an even frequency
response in all listening positions. Incorrect placement
leads to bass boom in some areas. Oen the only
way to nd a good position for your subwoofer is by
experimentation. A good place to start experimenting
is close to a wall but at least 1m away from any corners.
You can also consult your subwoofer handbook for
placement suggestions.
Front left and right
Position your front le and right speakers to
achieve a good stereo image for normal musical
reproduction as well as for the multichannel
modes. If they are placed too close together there
will be a lack of spaciousness; if they are placed
too far apart a stereo image will appear to have a
large ‘hole’ in the middle and will be presented in
two halves. If there is no practical alternative to
placing the speakers widely apart, this eect can
be overcome in music reproduction by using the
centre sound extraction from the le and right
speakers (see Dolby Pro Logic II Music mode).
Centre
e centre speaker allows for a more realistic
reproduction of dialogue. e centre speaker
should have a similar tonal balance to the front
le and right speakers and be positioned at a
similar height.
Surround left and right
e surround le and right speakers reproduce
the ambient sound and eects present in a
multichannel home cinema system and should be
installed slightly higher than the listener’s ears.
Surround back left and right
e surround back le and right speakers
are used to add extra depth and better
sound localisation and should be installed
approximately one metre higher than the
listener’s ears. Place the two surround
back speakers such that there is an arc of
approximately 150 degrees between each
surround back speaker and the centre speaker.
e surround back speakers should face the front
of the room as shown in the diagram to provide
the largest ‘sweet spot’.
Subwoofer
A subwoofer will greatly improve the bass performance of
your system. is is useful for reproducing special cinema
eects, especially where a dedicated LFE (Low Frequency
Eects) channel is available, as with many discs encoded
with Dolby or DTS technologies.
More than one subwoofer unit may be required for larger
installations, particularly in rooms of a timber frame
construction. Multiple subwoofers need care in placement
because there may be cancellation eects between the
units and you may require expert advice.
