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
Subwoofer
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. To guarantee better acoustic isolation of the speaker from the floor, AURUM
upright speakers can accept spikes. Depending on the space and floor,
installation of spikes can be an advantage.
Send in the enclosed spike order coupon with your purchase receipt, and
quadral will send you the right spikes free of charge.
Installing the spikes
a) Lay the speaker with its back on a soft
support, such as a blanket, to protect the
sensitive surface of the housing.
b) Underneath the base plate there are four
screw sockets for installing the spikes.
c) Screw the threaded sleeves off the spikes’
threaded ends.
d) Screw the four spikes into their threaded
sockets and hand tighten.
