Safety�Instructions
The information described here does not relieve the user of the duty to follow the given safety requirements and legal regulations.
Warning
The technicians responsible for assembling are responsible for the safe setup and use of the speaker
and guarantee this.
To prevent damage to persons and property, you must set up the speaker in compliance with the specifications of applicable national standards.
At least 2 people are necessary to carry the speaker.
The speaker is solely for professional use in the manner described here.
When laying out the connecting cables, make sure that nobody can trip.
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.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG.
As a basic principle, you must visually inspect all components of the speaker 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.

K&F NOMOS XLC
Safety�Instructions�for�Stacked�Setups
Falling�speakers�pose�the�threat�of�fatal�injuries�to�people�near�them!
Be sure to follow the relevant national specifications, norms, and safety regulations.
Warning
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 10° 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.

K&F NOMOS XLC
Protecting�the�Speakers�/�Operating�Safety
NOMOS XLC speakers may only be used in combination with a K&F SystemRack. See chapter [System
Requirements for Use] on page 5.
Caution
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 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
•
using the speakers without K&F 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 con-nected, 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.
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.

K&F NOMOS XLC
Stacking�the�Subwoofers
Securely place the bottom subwoofer onto a level surface.
Stack the subwoofers on top of one another.
Make sure that the stacking feet of subwoofers stacked on top of one another are
securely positioned in the grooves of the
lower speaker.
You must additionally secure vertically standing stacked NOMOS XLC systems from
falling since the structural safety is not guaranteed, otherwise.
6.
Cardioid�Arrays�with�NOMOS�XLC
The subwoofer NOMOS XLC is a cardioid loudspeaker.
A cardioid array results in an increase of sound pressure towards the front because of the rear-facing
subwoofer. In the rear area (cardioid) or in the lateral side area (hypercardioid), on the other hand,
the sound pressure is clearly reduced.
With this, you achieve
•
less unwanted sound on the stage
•
low feedback
•
simplified miking
•
improved room acoustics with fewer reflections from the rear and side walls, or – when flown –
from the ceiling
•
simplified adherence of sound emission limits and therefore less noise disturbance for nearby
residential areas during open air events.

10. Transport�and�Storage
The housing of the speaker is protected against short-term moisture by a coating. It should still be stored,
transported, and used under dry conditions, though. The SEQUENZA 10 System is not designed for longterm use in a corrosive environment. NOMOS XLC
Make sure that the system is adequately ventilated during longer storage periods so that possible residual
moisture can escape from the equipment.
Furthermore, you should ensure that the NOMOS XLC System is protected from mechanical strain to
prevent possible damage.
We recommend using the optional soft cover.

But�please�do�not�dispose�of�them�at�official�collecting�points�for�recycling�either!
All KLING & FREITAG products are plain business-to-business (B2B) products. KLING & FREITAG products
labelled with a waste bin sign have thus to be disposed of by KLING & FREITAG alone. Please call KLING
& FREITAG at the number stated below if you have a KLING & FREITAG product to be disposed of. We
will offer you a straightforward and professional disposal with no costs involved.
If there is no waste bin sign on one of your KLING & FREITAG products, because it has been sold before
24 March 2006, then by law the owner is in charge of the disposal. In this case we will be happy to
assist and offer you proper ways of disposal.

Explanation: With the ElektroG (law relating to electrical and electronic equipment and appliances) we
have complied with the EU-directive on waste electrical and electronic equipment (WEEE, 2002/96/EC).
From 03/24/2006 onwards KLING & FREITAG GmbH has thus labelled all products mentioned in the
WEEE with a sign with a crossed out waste bin and a white bar below. This sign indicates that the disposal
as domestic waste is prohibited and that the product has been put into circulation on 03/24/2006 at
the earliest.
KLING & FREITAG GmbH has been legally registered as a manufacturer with the German registration
office EAR. Our WEEE registration number is: DE64110372.
For the German Registration office EAR we have accredited that our products are soleB2B products.

It�is�not�allowed�to�dispose�of�used�electrical�equipment�as�domestic�waste.
From 08/13/2005 onwards KLING & FREITAG GmbH has thus labelled all products for EU-Member countries as well as Norway, Iceland and Liechtenstein (except Germany) mentioned in the WEEE with a sign
with a crossed out waste bin and a white bar below. This sign indicates that the disposal on domestic
waste is prohibited and that the product has been put into circulation on 08/13/2005 at the earliest.
Unfortunately the European directive WEEE has been complied with implementing different national
provisions of law throughout all member countries, which makes it impossible for us to offer consistent
solutions for the disposal throughout Europe.
Responsible for complying with these provisions of law is the local distributor (importer) of each country.
For proper disposal of used products in accordance with these local provisions in the mentioned countries
of the European Union (except Germany) please ask your local dealer or the local authorities.
