Safe practice
The 3 position 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 the 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 ➊ (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 ➋ is always inoperative when the selector is set in the Bipolar position.
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 ➊. (fig.M).
Twin mode (6.1 or 7.1)
Left loudspeaker: set the selector in Front ➊ position. Connect the surround side channel to input ➊ and the surround back
center channel to input ➋ (fig.N).
Right loudspeaker: set the selector in Front ➋ position. Connect the surround side channel to input ➊ and the surround
back center channel to input ➋ (fig.N).
Note: the side channel is always connected to input ➊ for both left end right loudspeakers and the center channel always
to input ➋. 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.
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 ➊ position. Connect
the left back surround channel to input ➊ and the right back surround channel to input ➋ (fig.O).
