Reflex tube blocking
The blocking of the reflex tubes is recommended in the event that
the loudspeakers are placed close to a wall and / or the bass
reproduction is accentuated. If a subwoofer is used with the loud
speakers, the best and most uniform sound is often attained when
the reflex tubes are blocked.
Cleaning the loudspeakers
When cleaning the surface of the loudspeakers, we recommend
using a dry microfiber cloth. To remove difficult stains, the cloth can
be moistened with water and when necessary, a mild soapy
solution. When using a cleaning fluid to clean a painted or polished
surface, there is reason to first try the rear plate of the loudspeaker
to ensure that the surface of the loudspeaker is not damaged. For
cleaning an aluminium profile, we recommend that the same
substances are used as when cleaning painted and varnished
surfaces.
Fault situations
All Aurelia loudspeakers are measured, tested and checked at the
factory during their manufacture. If an error nonetheless occurs with
the loudspeakers, they should be returned to the relevant retailer.
The most common cause of faults are improper cable connections.
Ensure that the cabling and connections are made correctly. In the
event that no sound can be heard from the loudspeakers, you can
check the functionality by switching it to an operating loudspeaker
channel. If, in this event, the loudspeaker works, the fault is in
another location than the loudspeaker. In so far as the speaker
remains silent, it is possible that the speaker has been damaged.
Warranty
The warranty of the loudspeaker is five (5) years, from the date of
purchase. The warranty covers faults resulting from the manufacturing
process and materials, but not damages as a result of incorrect use of
the product. The most common fault caused by incorrect use is related
to damage to the tweeter element by an audio level which is too high.
Although the Aurelia Ambera tweeter elements have a protection
circuit to prevent damage due to wrong use, the tweeter element may
however become damaged in extreme cases. The bass units may be
damaged when excessive volumes levels are used.
In so far as the sound of the loudspeaker becomes distorted, it may a
sign of an excess volume level. In this case, the volume must be
lowered immediately. The warranty does compensate for damages
caused by audio levels that are too high.
The opening or removal of the loudspeaker's elements, connector
panel or any other part will result in the warranty becoming invalid.
