Focal 1000 Be - Manuel (Page 9)

Safe practice
The 3 positions mode selector has
been developed to suppress any short-
circuit risk or connection error when
two amplifiers are simultaneously
connected to SR 1000 Be. In order
to ensure best performance under
the chosen configuration, we strongly
recommend to carefully follow mode
selector connection and setting
instructions.
Turn off any amplifiers
connected to SR 1000
Be during each mode
selector operation!
Bipolar mode (5.1)
Set the right and left surround
loudspeakers back selector in Bipolar
position. Always connect the amplifier
to right and left SR 1000 Be input

(fig. L).
Note
: in bipolar mode, the
loudspeakers work together towards
the front and the back of the listening
area in order to cover it in a smooth
and consistent manner.
Note : input  is always inoperative
when the selector is set in the Bipolar
position.
Bi/Twin mode(7.1)
Back center speaker : when a third
back center loudspeaker is added to
the system, SR 1000 Be side channels
are to be set in Bi mode while the
surround center channel is to be set
in Twin mode. Set the selector in Front

position. Connect the left back
surround channel to input
and the
right back surround channel to input 
(fig. O).
Bipolar mode (6.1)
Set the extra back center unit back
selector in Bipolar position. Always
connect the amplifier to SR 1000 Be
center bipolar unit input
. (fig. M).
Twin mode (6.1 or 7.1)
Left loudspeaker : set the selector
in Front
position. Connect the
surround side channel to input
and
the surround back center channel to
input  (fig. N).
Right loudspeaker : set the selector
in Front  position. Connect the
surround side channel to input
and
the surround back center channel to
input  (fig. N).
Note : the side channel is always
connected to input
for both left
end right loudspeakers and the
center channel always on input .
That approach permits switching the
selector from Bi mode to Twin mode
without wiring modification.
Note : Twin mode allows back and
side surround information to be
carried simultaneously to a single
surround loudspeaker, dividing it in
two parts beaming towards the front
and the back of the listening area.
Note
: surround side channel
information will be carried to the front
while center channel information will
be carried towards the back of the
listening area thanks to the two sets of
separated connectors.
