Quadral AURUM ORKAN aktiv - Handbuch (Seite 6)

• Never use the equipment in the vicinity of water, in humid areas or outdoors.
Moisture can bypass the electrical insulation and this will create a life-threatening
risk as is the case with all equipment that has not been specially designed against
the penetration of moisture.
• Protect the equipment against water being sprayed on it. You must also ensure
that no vessels containing liquid (e.g. vases) are placed on top of the equipment.
• Do not place the equipment in the vicinity of a heat source such as an electric
fire, radiator, oven or similar.
• The slits and openings in the enclosure provide the ventilation and ensure reliable
operation. They must never be misaligned or covered.
• Burning-out of specific components cannot be completely excluded, despite the
use of protective devices, if the equipment is severely overloaded by continually
using very loud sound levels. A fire might also be caused inside the equipment in
theory, as a result of this type of overloading. Therefore the amplifier should always
be used within its limits and it should not be left unattended.
• Only our technical service should undertake the maintenance of your equipment.
Maintenance will be necessary if any type of damage occurs, i.e. if the power
cables or plugs are damaged, if an object falls on the equipment, if the
equipment is dropped or if liquid seeps into it. Never open the equipment as you
might touch the mains voltage (230V / 115V), which is dangerous.
• Only use furniture and other units for attaching and putting the equipment on
that can be obtained from or are recommended by the manufacturer. You must
ensure that moveable tabletop units or shelves on which the equipment will be
placed are always moved very carefully in order to prevent damage or injuries
from being caused if the equipment tips over.
• Continuously loud volume can damage your hearing!
• Only use a dry, soft cloth to clean your equipment.
• Keep the packing for possible transportation use later on and keep the plastic
bag well away from children, due to the risk of asphyxiation.
Setting up
To obtain optimal sound results, it is generally necessary to try out different set-ups.
Since the room conditions have a major effect on sound reproduction, we suggest
below a few useful approaches for positioning your
AURUM loudspeakers.
Where the speakers are positioned in the listening space has a decisive effect on
their sound. 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 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. With their slanted fronts, the floorstand
speakers are specially adapted to acoustic demands. Bookshelf speaker units sound
best on a speaker stand or shelf, with the tweeters arranged at ear height. The cases
should be angled and slightly tilted to achieve this.
So 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.
