GRAVIS 12+ speakers may only be used in combination with a K&F SystemAmp/SystemRack.
In general, audio signals must not be overdriven. This may be caused by mixing consoles,
equalizers, effect equipment, etc. and should be indicated on this equipment. When a power
amplifier is overloaded at the output (clipping), then the amplifier activates a clipping
warning signal. In any case, the signal must be reduced as soon as it sounds unnaturally
distorted.
For damage caused by
•
overloading the speakers or
•
using the speakers without K&F SystemAmp/SystemRack
we do not assume warranty and excludes liability for possible consequential damage.
The following signals may damage the speakers:
•
permanent high-level signals with high frequency and continuous noise from feedback,
•
permanently distorted high-level signals,
•
noises, which occur when the amplifier is on while equipment is being connected,
disconnected or switched on.
Do not install devices in any of the following places:
•
where the devices are permanently exposed to direct sunlight.
•
where the devices are exposed to high moisture or rain.
•
where the devices are exposed to strong vibrations and dust.
Damage caused by the speakers' magnetic fields
Speakers are permanently surrounded by a magnetic field, even when they are not
connected. Therefore, during transport and placement of the speakers, it is important to
ensure that there is always approx. 1 m between the speakers and magnetic data media and
computer/video monitors.
