3. Safety Instructions
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.
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.
Warning
Warning
3.1 Notes for Mounting the Speakers
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall.
Please note that speakers can move as a result of vibrations. To prevent them from falling
from their mounted position, they must be secured properly.
When laying out the connecting cables, make sure that nobody can trip.
3.2 Instructions for Speaker Stacking
Falling speakers pose the threat of fatal injuries to people near them!
Be sure to follow the relevant national specifications, norms, and safety regulations.
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.
KLING & FREITAG GMBH © 2014 Version 1.0 Page 7 of 21
User's manual K&F NOMOS LS II
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 LS II you must always strap the speakers to one
another and secure them from falling over.
3.3 Protecting the Speakers / Operating Safety
NOMOS LS II speakers may only be used in combination with a K&F 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
• 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 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.

4. Setup
4.1 Removing the Transport Covers
To remove the transport lid, turn the appropriate catches 180° to completely release the
latch.
Lift the lid from the speaker.
4.2 Stacked Setup
1. Securely place the bottom subwoofer
onto a level surface.
2. 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.
3. Stacked systems must be stable even if
they are inclined by 15 degrees without
additional additional securing.
If this is not the case the systems have to
be secured against falling over in order to
guarantee the stability of the stack.

5.4 Cardioid Arrays with NOMOS LS II
The subwoofer NOMOS LS II is designed so that it can be used as a cardioid system in an array
of three subwoofers, or in multiples of three.
A cardioid array results in an increase of sound pressure towards the front because of the
rear-facing subwoofer. In the rear area, 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.
5.4.1 Setup instructions for a cardioid array
To achieve a cardioid pattern, you must always have an array with 3 subwoofers - or a
multiple of 3 subwoofers - setup next to one another (3, 6, 9, etc.). In this set of three, the
middle one must be rear-facing while both other subwoofers are front-facing.
You can choose from the following options for cardioid and hypercardioid setups:

5.4.2 LSBlocks for cardioid use
The rear-facing subwoofer is controlled using the Controller CD 44 via LSBlock for cardioid
arrays for rear-emitting subwoofers. The front-facing subwoofers are controlled via LSBlock
for cardioid arrays for front-emitting subwoofers. The following cardioid LSBlocks are
available in the Controller CD 44:
Operation Mode Chassis LSBlocks
'Cardioid' front NomLS2 C-F
'Hypercardioid' front NomLS2 H-F

5.5 Cardioid Configurations with different Speakers
NOMOS LS II are suitable for cardioid configurations with certain K&F speakers. A chassis ratio
of 1 to 2 should be maintained within these configurations.
The speaker with one chassis should be standing on the floor and directed to the rear while
the speaker with two chassis directs to the front.

Warning
6. Fuse in the NOMOS LS II
To increase the operating safety of the NOMOS LS II, the subwoofers are equipped with fuses
at the signal input. These fuses reduce the risk of consequential damage resulting from a
short circuit (i.e. charred cables / connectors / fire damage).
When the fuse is burned out, then the chassis is most likely already ruined, as the fuse just
prevents consequential damage resulting from a short circuit of the chassis. A replacement of
the chassis is, therefore, unavoidable.
6.1 Replacing the Fuses
The fuse holder is behind the terminal.
Replace the fuse with the following original fuse only:
Bussmann S 506-8A, T 250V
Required tools:
• 2.5 mm Allen key for loosening the terminals
Instructions:
1. Loosen the four screws on the terminal.
2. Carefully pull the cables out of the speaker enclosure.
3. Open the fuse holder.
4. Replace the blown fuse.
5. Push the cables carefully back into the enclosure.
6. Pay attention to the correct alignment of the terminal.
Screw the terminal back on.

User's manual K&F NOMOS LS II
6.2 Replacing the Chassis
Required tools:
• 3 mm Allen key for loosening the front grille
• 3 mm Allen key for loosening the chassis
Instructions:
1. Remove the front grille.
2. Remove the speaker chassis.
3. Pay attention to the correct polarity of the chassis.
Connect the new chassis.
4. Check the polarity of all mounted chassis.
5. By tightening the screws diagonally in two steps, a deformation of the chassis and thus a
possible deentring of the voice coil can be avoided. First loosely fasten the screws for the
chassis diagonal from one another, then tighten them.
6. Mount the front grille.
7. Transport and Storage
Warning
The NOMOS LS II is protected against short-term moisture. The accessories has to be stored,
transported and used in a dry enviroment. The NOMOS LS II System is not designed for longterm use in a corrosive environment.
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 LS II System is protected from mechanical
strain to prevent possible damage.
We recommend using suitable transport and storage cases and the optional soft cover that
protects from the above-mentioned influences.
8. Maintenance and Care
For the owner and user, it is mandatory to be aware of the safety relevance of speakers that
can be flown.
The NOMOS LS II system can exhibit signs of wear over the years, i.e. from mechanical strain,
transport damage, corrosion, or improper handling. If speakers are to be flown, this always
means there is a high safety hazard.
As a basic principle, you must visually inspect the accessory every time you suspend it and
take it down. NOMOS LS IIFor fixed installations, you must inspect the speaker for signs of
wear at regular intervals.
During these inspections, you must especially look out for deformations, cracks, dents,
damage to threads, and corrosion. Mounting devices such as shackles, chains and wire ropes
also have to be checked for signs of wear or deformation carefully.
If as a result of these checks any uncertainty should arise with regard to safety or if specific
faults are found, the accessory may no longer be used and you must send in the product to
KLING & FREITAG GmbH for inspection and repairs, if necessary. If defects are ascertained,
then you must send in the product to KLING & FREITAG GmbH for inspection and repairs, if
necessary.
The inspection requirements vary depending on application and country of use. Observe the
requirements that are relevant for you. If in doubt, contact local authorities.
In many countries, regular inspection of mounting components and accessories is required.
In most cases (e.g. german BGV C1), an additional annual inspection is required that must be
done by a technical expert. Additionally, a detailed inspection carried through by a legally
certified or official authority is required every four years.
KLING & FREITAG GMBH © 2014 Version 1.0 Page 15 of 21
User's manual K&F NOMOS LS II
In this context, it is very important to keep an inspection log book. In this inspection log
book, the data for every used accessory is entered at the periodic inspections, making the
data available at all times for possible inspections. This book should document maintenance
measures and inspection intervals and contain parts lists.
The Polyurea synthetic coating used by KLING & FREITAG is impact proof and highly resistant.
We recommend using protective coverings or cases to help avoid damaging the paint during
i.e. continuous mobile use
To replace the filter foam, send the front grille incl. foam to KLING & FREITAG GmbH. Upon
payment for expenses, the grille with the new covering will be returned.
