1. General Safety Instructions for Using Speakers
Mounting the speakers
To prevent injury or property damage, this equipment must be securely placed on the floor
Warning
or secured to the wall according to the mounting instructions on page
Instructions for Loudspeakers)
tions. To prevent them from falling from their mounted position, they must be secured
properly.
Speakers may only be mounted to walls and ceilings by qualified personnel. The speakers
must be hung by using at least two of the designated flying points. The same applies
when lifting and aligning the speakers.
Never use signal cables or power cords for suspending, aligning or securing the systems.
When laying the connecting cables, make sure that nobody can trip.
When suspending the speakers use only mounting equipment from Kling & Freitag.
Ensure that all installation connections comply with the applicable safety guidelines and
that the size and strength are sufficient. Further instructions are in our user's manual for
assembly equipment and in the general safety instructions for speakers and assembly equipment.
For mobile and fixed installations, use only assembly equipment from Kling & Freitag.
Make sure to observe the included safety and mounting Instructions for loudspeakers and
accessories.

Warning
Speakers and rigging equipment must be visually examined at regular intervals. If there
are signs of wear, they must be replaced immediately. Furthermore, screwed connections
of supporting parts must be checked routinely.
Protecting the speakers / avoiding fire hazard
In general, audio signals should 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 should activate a
clipping warning signal. Power amplifiers can also be overloaded at the input circuit without the amplifier signalling the clipping, i.e. when there is not sufficient headroom in the
input circuit. We, therefore, recommend turning up the power amplifiers all the way and
adjusting the level before the power amplifier in order to avoid overloading the input circuit. In any case, the signal must be reduced as soon as it sounds unnaturally distorted.
To protect the speakers from being destroyed and to avoid fire hazard, they should
only be operated with professional power amplifiers with the following specifications:
− Integrated or preceding subsonic filter (approx. 20 Hz, min. 12 dB / octave)
− Integrated clipping limiter
− Maximum rated power 300W@8Ω (equivalent 600W@4Ω)
For damage caused by overloading or use with power amplifiers other than those recommended above, Kling & Freitag GmbH does not assume warranty and excludes liability for
possible consequential damage.

User’s Manual E 90 MK II
The following signals may damage the speakers
− permanent high-pitched signals with high frequency and continuous noise from
feedback.
− permanently distorted signals with high power.
− noises, which occur when the amplifier is on while equipment is being connected,
disconnected or switched on.
Important
Do not install speakers in any of the following places:
− where the speakers are permanently exposed to direct sunlight
− where the speakers are exposed to high moisture or rain
− where the speakers 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 operating. 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.
Preventing hearing damage
To prevent the risk of hearing damage, avoid being too close to operating speakers, even
if the volume level seems to be low enough. In general, volume levels over 90 dB can cause hearing damage.
