Loudspeaker choice
Your loudspeakers have been developed to be used in Stereo and Home Theater configurations. If you already use
Sopra loudspeakers at the front and want to move forward to Home Theater, it is paramount to use the Sopra Center
unit and surround Be loudspeakers.
You can also use in-wall Electra IW 1002Be or Electra 1002-Be when environment limitations do not allow you to use
Surround Be loudspeakers.
The SW1000 Be subwoofer perfectly completes any Sopra multichannel configuration.
Sopra Center loudspeaker positioning
The Sopra Center loudspeaker must be placed within close range of the screen for realistic dialogue reproduction. If
a standard projection screen is used, the center unit must be placed right under the screen for optimal performance.
If a perforated, acoustically transparent screen is used, the center unit can be placed behind, at the lower half of the
screen. (Fig. J)
Surround Be loudspeakers installation
Securely fasten the fixation rails onto the wall using the provided plugs and then insert the Surround Be (Fig. K).
Surround Be positioning
As it is detrimental to perception, avoid placing the surround loudspeakers too far back in the listening area. The
best location can be obtained when Surround Be loudspeakers form a 120° to 160° angle with respect to the listener.
(Fig. L). Place Surround Be loudspeakers sufficiently high, (between 50cm and 90cm) above the listener's ears.
Surround Be Bi/Twin Modes
This speaker features a double Bi/Twin operating system allowing it to be used either in standard bipolar mode (Bi)
or in double monopolar mode (Twin). Adequately defining parameters on the three positions mode selector and on
the double input connector, (providing one or two power amplifier connection capabilities for each speaker) enables
Surround Be to implement 5.1 or 7.1 configurations using only one pair of surround loudspeakers. (Fig. M)
This selector authorises the loudspeakers to work together or divided in two groups ( and ), carrying different
information to both the front and rear of the listening area (Fig. N). The three position mode selector allows you to
choose between the "Bipolar mode" and two "Twin modes" (Front  and Front ), according to the speaker direction
(Fig. O).
