speaker that should be placed behind
and slightly above the typical listening
position.
Rear speakers
Whether you direct the rear speakers
toward the listening position is a matter
of taste. Also, many listeners prefer the
rear speakers to be positioned above
ear height. This can be achieved
by mounting the units on a sturdy
wall bracket, a high speaker stand, a
sideboard or shelf.
Stands
For optimal front and rear speaker setup, quadral has suitable stands in its product
range.

Connecting to the amplifier
Before connecting up the speakers to your hifi 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 mm
2 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.
For operating AURUM VIII speakers with
bi-wiring/bi-amping, both screw terminals for the woofers are located below, and for
the midranges and tweeters above on the connection panel.
Make sure you use the correct polarities in these modes and that you remove the
jumpers on the speaker terminal to avoid damaging your amplifier.
