During Bi-wiring / Bi-amping operation of the
AURUM
loudspeaker, both screw terminals for the woofer (LO)
are below and for the midrange speakers and tweeters (Hl) are above on the connection plate.
Only the largest models of the
AURUM 9
series are fitted with an extended connector panel by means of
which these connections are arranged horizontally and the various operating modes apply analogously with
the assignment of (Hl) and (LO).
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.
OPERATION WITH A SURROUND AMPLIFIER
Once you have positioned and connected your speakers as shown in the illustration, you should perform the
necessary settings in the bass management system of your surround amplifier.
Make sure you read the user manual supplied by your amplifier’s manufacturer before doing this.
Since bass management primarily depends on the loudspeaker configuration, we give only typical settings
below.
a) Small and very small satellite speakers must be operated in “small” mode.
Perform the setting on your amplifier as follows:
Front:
small
Centre:
small
Rear:
small
Subwoofer:
yes
b) There is no definitive formula for the settings for compact speakers. In this case, the suitable mode may be
“large” or “small”. This depends on the volume level you prefer or the sound effect you wish to obtain (refer
to the section “Caution, clipping!”). The settings on your amplifier can optionally be configured as follows:
Front:
large/small
Centre:
large/small
Rear:
large/small
Subwoofer:
yes
c) Floorstanding speakers or large bookshelf speakers that are suitable for powerful bass reproduction
should be operated in “large” mode.
Perform the setting on the amplifier as follows:
Front:
large
Centre:
large
Rear:
large
Subwoofer:
yes/no

If your surround amplifier has a “line subwoofer” output, you can make use of this by using the Y cable supplied
with the subwoofer (see illustration page 8). In this case, you connect the front speakers directly to the front
speaker terminals of your amplifier. Refer to the connection diagram for wiring your surround system.
Refer to the user manual of the active subwoofer for the necessary settings on your subwoofer!
TIPS FOR BETTER ACOUSTICS
1. The AURUM stand-mounted loudspeakers are fitted with a holder for spikes in order to achieve better
acoustic decoupling of loudspeaker from the floor. Use of spikes can be advantageous dependent on the
nature of the living room and the floor.
AURUM spikes can be obtained separately as an accessory from your dealer.
2. In order to achieve better acoustic decoupling from the mounting surface for shelf or centre speakers, lay
each of these loudspeakers on 4 self-adhesive felt washers.
