Positioning speakers
This unit has two sets of speaker system terminals (for
SPEAKERS A and SPEAKERS B).
Before connecting the speakers, place them correctly by
consulting the instruction manuals that came with them.
For surround playback, the configuration and placement of your
speakers are very important.
Standard speaker system for reproducing
surround sound
Front right and left speakers
Center speaker
Produces a rich sound image by serving as a sound source for
the front right and left speakers and enhancing the sonic
movement.
Surround right and left speakers
Adds three-dimensional sonic movement and produces
environmental sound associated with the background and
effect sound for each scene.
Subwoofer
Produces powerful and heavy bass.
If the subwoofer and center speaker are not
available
The sound recorded for the center speaker and the subwoofer will
be properly distributed to the front right and left speakers for
optimized surround playback.
Speaker placement
Ideal speaker placement varies depending on the size of your room
and the wall coverings. Here, only typical example of speaker
placement and recommendations are shown.
Important points regarding speaker placement
Front left and right speakers and center speaker
Place these three speakers at the same height from the floor.
Place each speaker so that sound is aimed at the location of the
listeners ears at the listening position.
Install the left and right front speakers at the same distance
from the listening position.
Surround left and right speakers
Place these speakers so that their height is 1 meter (3.3 feet)
higher than that of the listeners ears.
Subwoofer
The subwoofer can provide a similar sound effect regardless of
the installation position, provided that it is installed within the
room containing the listening position.
