Setting up
As a rule you should try various set-up positions in order to get the best sound
results.
Since the positioning of loudspeakers decisively influences the quality of the sound
they deliver, we’ll start by giving you some hints on how and where to set your
AURUM units up.
Placing the speakers near the corners of the room will essentially give you loud
bass reproduction but with little outline. On the other hand, speakers positioned well
away from the walls sound precise, but also very bright and thin. The best solution is
to place the speakers with a clearance of at least 30 cm between their backs and
the nearest wall. To avoid loud wall reflections, the distance from the side walls of the
room can even be 50 cm or more.
As far as possible, the speakers should be equidistant from the listening position, while
the distance of the speakers from each other can be rather less than the distance
from the listener.
Positioning your speakers on hard floor surfaces
If your AURUM floorstanding speakers are going to be placed on a hard floor
surface, for instance on tiles, stone, parquet or laminate, we urgently recommend
that you fit the supplied rubber mats in place under the cabinet base. These mats
will protect your speakers as well as the floor from damage while compensating
any slightly uneven spots. However, you will not need to use them where soft
floor surfaces such as carpets are concerned since the aluminium discs pre-fitted
between the cabinet and base already serve the purposes of acoustic decoupling.
When fitting the rubber mats (S) onto the speaker base you will need a helper as
well as the cardboard angle strip that you will find in the speaker
packaging. We recommend doing so on each of the speakers
as follows:
• Firstly, determine where you definitively wish to position the
speaker in the listening area and have the angle strip and
rubber mat ready to hand.
• Your helper should now tilt the cabinet slightly to one side
so that you can slide the angle strip one centimetre (at the
most!) under the raised edge of the cabinet base.
• Your helper should now tilt the cabinet slightly to the other
side and hold it in this tilted position while you fit the rubber
mat precisely into place under the raised base; when doing
• At high volumes, voltage levels of 30–50 V can be present at speaker terminals
and components. Be very careful not to touch uninsulated terminal contacts of
speakers when in operation. To avoid injury, never put hands or arms into sound
outlets (bass reflex tubes). Children and pets, in particular, are at risk from this.
• For safety reasons, we generally forbid the opening of loudspeaker cabinets
when in operation or connected since, as explained in the above paragraph,
voltages of up to 50 volts can be present inside.
• Improper handling of mains voltage can cause fatal injury!
Passive loudspeakers must on no account be connected to the electricity
supply!
Speaker terminals may only be connected to the appropriate output terminals
of the amplifier. You should never connect these terminals to the electricity supply
(230 V/115 V) in any way since that will otherwise also immediately destroy the
loudspeaker and all connected products. Avoid fitting plugs to ends of speaker
cables that could even remotely be confused with mains supply plugs.
• Loudspeakers that are not magnetically shielded can affect the colour of the
TV picture or cause distortion. A distance of 50 cm is generally sufficient to avoid
problems of this kind. Avoid placing items such as credit cards, diskettes, audio or
video cassettes or other magnetic media on the loudspeaker. This could destroy
the information stored on them. Similarly, avoid operating magnetic tape devices
in the immediate vicinity.
