ADJUSTING THE RELATIVE SPEAKER BALANCE
After installing your Surround and/or Centre speakers, you will
have to find a good sound balance between the Surround, the
Centre and the Front speakers.
• On the amplifier or receiver, switch on the SURROUND
mode.
• In the instruction booklet of the amplifier or receiver you will
find a section describing how to adjust the sound level of the
Centre and the Surround speakers.
• For the Surround speakers, it may be possible to adjust the
delay time as well. This means that the surround sound is
reproduced somewhat later than the sound of the front
speakers, giving the sound impression of a larger room or
even a hall.
• Adjust the sound level of the surround and centre speakers
and also the delay time for the Surround speakers at your
personal taste. The settings are kept by the amplifier or
receiver.
POWER HANDLING_______________________________
Each amplifier or receiver used at high power over a long
period of time can produce distortions which may seriously
damage your speakers.
Your ears will warn you, since the speakers will indicate
overloading by giving severe distortion.
If this happens, reduce the volume and tone controls to a level
where the sound is acceptable again.
Remember
Speakers are most often damaged when they are overdriven
by under-powered amplifiers.
MAINTENANCE__________________________________
• A chamois leather slightly moistened with water is sufficient
for cleaning the speakers.
• Do not use cleaning agents containing alcohol, spirits, am­
monia or abrasives.
• Do not leave the speakers for any length of time in direct
sunlight or other places where high temperatures can occur,
such as in the vicinity of heating apparatus.
• Do not expose the speakers to humidity or rain.

If a fault occurs, first check the points listed below before
taking the speakers for repair
If you are unable to remedy a problem by following these
