4. Safety Instructions

Warning

The speaker is solely for professional use in the manner described here.
To prevent damage to persons and property, you must set up the speaker in compliance with

the specifications of applicable national standards.
The information described here does not relieve the user of the duty to follow the given

safety requirements and legal regulations.
The technicians responsible for assembling are responsible for the safe setup and use of the

speaker and guarantee this.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG.
If not otherwise stated in this manual, only original KLING & FREITAG parts may be used. The

use of other parts - in particular parts by other manufacturers - is not permitted.
As a basic principle, you must visually inspect all safety-relevant components of the speaker

and the accessory before every use. For fixed installations, you must inspect the speaker for
signs of wear at regular intervals. If there are signs of wear, cracks, or deformation, etc. then
you must replace the parts immediately.

Caution

When laying out the connecting cables, make sure that nobody can trip.
At least 2 people are necessary to carry the speaker.

Preventing hearing damage

Avoid beeing too close to operating speakers. Even loudness levels of approx. 90 dB - that
you subjectively judge as being low - can lead to hearing damage.

4.1 Safety Instructions for Stacked Setups

Warning

Falling speakers pose the threat of fatal injuries to people near them!

Be sure to follow the relevant national specifications, norms, and safety regulations.

User's manual K&F NOMOS XLC

KLING & FREITAG GMBH © 2014 Version 4.1 Page 6 of 21

Always make sure that a sufficient safety level is still given, even when outside forces have
an additional impact on the stacked speakers. Before setup, carefully ascertain if there are
any possible outside forces that could result in the array falling over. (Slant of the ground /
the bearing capacity of the ground / wind / person or vehicle impact, etc.). A technical expert
who is responsible for the setup must evaluate and determine necessary measures (including
calculating the statics). If necessary, obtain expert proof of stability.

Stacked systems may not fall over even if they are inclined by 15° in each direction. If this
requirement is not fulfilled, then it is necessary to take steps to achieve compliance. Possible
measures include strapping it to an appropriate base structure or fastening it using safety
straps. A planned tilt of the loudspeakers ist not permissible. In calculations, the tilted setup
serves the purpose of levelling out unevenness.

With the set-up systems for which you cannot verify the structural safety without safeguards,
you must secure them to prevent sliding or tipping in order to provide proof of this safety. To
secure the system from tipping over, use water tanks or floor bolts. Other possible measures
include strapping it to a suitable substructure or tying it using safety straps.

For outdoor and trade fair venues in which wind loads must be considered, additional proof
of stability is necessary.

Make sure that the stacking feet of subwoofers stacked on top of one another are securely
positioned in the grooves of the lower speaker.

If you place a top speaker on a NOMOS XLC you must always strap the speakers to one
another and secure them from falling over.

4.2 Protecting the Speakers / Operating Safety

NOMOS XLC speakers may only be used in combination with a K&F SystemRack.
5System Requirements for Use

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.

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.

• where low air circulation (convection) prevails.

• that have a small distance to a wall.

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.

For damage caused by

• overloading the speakers

• using the speakers without K&F SystemRack

we do not assume warranty and excludes liability for possible consequential damage.
