so, make sure that the groove in the mat is at the back, in
other words beneath the rear side of the cabinet.
• When this has been completed your helper can then
carefully tilt the speaker back into its stable upright
position.
Connecting to the amplifier
Before connecting up the speakers to your hi-fi or surround sound system, please
ensure that the amplifier/receiver is switched off and its pilot light is not on. For
connection, you will need a twin-core loudspeaker cable for each speaker cabinet.
Make sure these cables are sufficiently long and cut them to a length that will
subsequently enable you to lay them behind furniture or under the carpet where
necessary. For cables more than 5 m in length we recommend a cross-section area
of at least 2.5 mm2 per core in order to avoid any unnecessary loss of output. To
enable optimum contact, about 10 mm of the cores at each end of the cable must
be isolated, and thus bare.
Screw terminals
For connection, the speakers are provided with colour-coded screw terminals on
the back of the cabinet. Loosen the screw terminals and feed the stripped end
of the core into the hole that is now free. The two cores of speaker cables have
different colouring or shape for recognition. Connect the “+” core to the red, positive
terminal – the remaining core to the black terminal. Tighten the screws hand-tight.
To ensure correct polarity, check that the core connected to the red “+” terminal of
the speaker is also the core that is connected to the red “+” terminal of the amplifier
and that the other core is connected to the black “-“ terminals of both the speaker
and amplifier.
With AURUM loudspeakers you can choose between three modes of operation:
a) Conventional mode
Do not remove the jumpers, connect the speaker cable as shown in
the illustration.
b) Biwiring mode
Remove the jumpers after loosening the four screw terminals on the back of
the speaker and connect the cable as shown in the illustration.
c) Biamping mode
Remove the jumpers and connect the cables as shown in the illustration.
