Some quadral rear speakers have an additional
tweeter on the back of the cabinet to achieve an
especially broad sound image. If you want to stand or
lay these with their backs directly against the wall, you
should disconnect this additional tweeter by removing
the jumper of the connecting terminal. When you
remove the jumper on the terminal, the tweeter at the
back no longer receives electrical signals and is silent.
The rear speaker then becomes a conventional two-way
box.
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
For the special
quadral centre speakers, we generally recommend “small” mode.
Subwoofer
If your surround amplifier has a “line subwoofer” output, you can make use of this by
using the Y cable shipped with the subwoofer (see illustration). 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!
