Positioning speakers/Connecting speakers
Two speaker systems can be connected to the Receiver.
The speaker system A is to be placed in the main room, and the speaker system B is to be placed in a second room.
The speaker system A consists of the FRONT SPEAKERS A (L/R), CENTER SPEAKER, SURROUND SPEAKERS (L/R) and
SUBWOOFER.
You can reproduce the sounds such as Dolby surround and DTS surround.
The speaker system B consists of the FRONT SPEAKERS B.
You can reproduce only monaural and stereo sounds.
Standard speaker placement of the speaker system A
Speaker placement plays an important role in the reproduction of
Surround sound.
The placement of the speakers varies depending on the size of the room
and the wall coverings used in the room. The illustration below shows an
example of a layout for standard speaker placement. Refer to this example
when you position the speakers in order to experience the best of
Surround sound.
For ideal Surround effects, all speakers should be installed.
If a center speaker or subwoofer is not connected, the sound from the
unused channel is properly distributed to the connected speakers in order
to reproduce the best Surround sound possible.
Front
The center speaker reproduces a richer sound image by enhancing the
perception of the sound’s source and movement.
The left, right, and center speakers should face the seated listener and be
placed at ear level.
Surround
The surround speakers reproduce the feel of a moving sound while
creating the sensation of being in the middle of the action.
Place the left and right surround speakers 3 feet (1 meter) above the
listener’s ear level and facing toward the sides of the room, making sure
that the listener is within the speakers’ dispersion angle.
Subwoofer
When bass sound is reproduced, its volume and quality greatly depend on
subwoofer placement. Those characteristics also depends on the shape of
your listening room as well as your listening point. Generally speaking,
good bass sound is obtained when the subwoofer is placed in the corner of
the room or at one-third the length of the room.
Refer to the speakers’ instruction manuals for details.
