To prevent injury, the speakers must be securely placed on the floor or secured to the
wall according to the instructions on page 17 (Mounting Instructions for Speakers).
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. If the weight of the
speaker exceeds 20 kg then it is necessary for two people to carry it.
Speakers may only be suspended or mounted to walls or 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.
Never hang more than two speakers under one another without using the designated
Kling & Freitag rigging equipment.
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 rigging equipment from KLING & FREITAG.
Make sure to observe the included safety and mounting instructions for loudspeakers
and accessories.
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.
Warning
Protecting the Speakers
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 clipping limiter
− without using a Kling & Freitag controller:
Integrated or preceding subsonic filter (approx. 20 Hz, min. 12 dB / octave)
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.
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 devices in any of the following places:
− where the devices are permanently exposed to direct sunlight.
− where the devices are exposed to high moisture.
− where the devices are exposed to strong vibrations and dust.
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
Important
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
Caution
can cause hearing damage.

4. Notes for the SW112 / SWi 112 with Option ‘100V’
Kling & Freitag speakers with ‘100V’ option are fitted with high-quality toroidal transformers. This serves to minimize loss of sound. Highly professional sound reinforcement
results can be achieved by using 100 V Kling & Freitag speakers.
4.1 Reasons for choosing Speakers with 100 V Technology
− Reduction in conduction loss.
− Easy assembly of a loudspeaker network due to simple parallel wiring.
The sum of the output power of the individual speakers (stated as VA = W)
must not exceed the output power of the 100 V amplifier.
− Speakers are galvanically isolated.
Important
− Speakers can be integrated into existing 100 V systems.
The speakers may only be suspended by trained specialised personnel with
proof of their qualifications.
Observe the prescribed safety factors. Follow the safety instructions for
speakers and mounting equipment as well as the respective national rules,
Warning
norms and safety regulations.
Speaker systems, whether single or connected to one another, must always be secured
to a second separate point, even if two rigging points are used for suspending the
speaker system!
A maximum load of 73 kg may be hung below one SW 215E subwoofer. This means a
maximum additional load of 36.5 kg on each flying point.
A maximum load of 50 kg may be suspended from the two flying points of all other
subwoofers. This means a maximum additional load of 25 kg on each flying point.
Ensure that all connections are secured to prevent their detaching on their own and
that only admissible statically tested and sufficiently sized mounts, connecting devices,
ropes and chains are used.
5.1 SW 215E and Click & Fly Accessories
The Click & Fly rigging system is a certified and type tested rigging system for safe and
comfortable rigging of SW 215E or Line 212 systems.
Click & Fly Systems with the classification of ‘CLICK & FLY RIGGING SYSTEM’
may not be used with the SW 215E Systems without the supplementary

5.2 Subwoofers with ‘Flying Thread’ M12 (SWi Versions)
If you want to use the SP subwoofers equipped with ‘flying threads’ M12, please read
the following instructions.
Appropriate fastening mechanisms with an external screw thread of M12 and a minimum length of 35 mm! may be screwed on to the M 12 thread inserts. The internal
screw threads in the speaker enclosure are fastened during production with countersunk head screws M12.
The two internal screw threads of the inner enclosure edge are on an L-bracket. This Lbracket has the function of connecting the adjoining plates of the enclosure. It provides
sufficient tensile strength for flown operations. To guarantee that the enclosure plates
are correctly connected by the L-brackets, only one screw of the enclosure edge may be
loosened at a time. If both screws of an enclosure edge become loose, then, for safety
reasons, the L-bracket will collapse into the enclosure.
If the L-bracket has fallen into the enclosure the loudspeaker must on no account be used again until it has been repaired by an authorized repair service.
When mounting the speakers, use only fastening mechanisms with threads that extend
at least 35 mm into the speaker enclosure. Take into account the permissible load capacity of the fastening mechanisms while considering the safety factors. Mount the
speakers using at least two independently operating points. Secure all screws to prevent
loosening.

5.4 SW 215E ‘Suspension’: Using the allsafe Flying Track
The subwoofer SW 215E with suspension option may only be suspended by using the
double stud fittings available from Kling & Freitag. The ‘allsafe JUNGFALK’ flying tracks
are used to suspend the SW 215E system.
We recommend using the certified Click & Fly Line 212 / SW 215E rigging system for
suspending the SW 212E.
The ‘allsafe JUNGFALK’ flying track can only support weights up to 73 kg on
one point!

trip.
The stability of stacked systems (also valid for the use of stands and distance rods!) is
contingent upon the following stability requirement. These conditions must, therefore,
be guaranteed by the user:
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.
6.1 Using the Mounting Equipment ‘Distance Rod’
The subwoofer is equipped with a threaded flange (M20) on the top of the enclosure
for mounting the optionally available distance rod (not on the SWi versions).
All K&F top speakers with a mounting flange or stand adapter may be mounted on the
distance rod. Only use authentic Kling & Freitag distance rods and stand adapters. We
can only guarantee safe operations when these parts are used.
Caution
When a top speaker is mounted on the subwoofer using a distance rod, the stability of
the speakers is reduced. Please follow the stability requirements in chapter 6!
When re-positioning after set-up, remove the upper speaker mounted on the distance
rod first.
Special note for the model SW 112
A top speaker with a maximum weight of 28 kg (i.e. CA 1201) may be mounted on this
speaker using a distance rod. Speakers, which are heavier than 28 kg, may not be
mounted on the distance rod flange and must be mounted on an additional speaker
stand.
In addition to the stacking foot
grooves for stacking the same

7. Short Circuit Fuses in the K&F Subwoofer Systems
7.1 Risks of using High Performance Power Amplifiers
In recent years, power amplifiers have achieved increasingly higher levels of performance. Some of them can be operated with low-impedance loads. There are, therefore,
strong power amplifiers that can reliably work with impedances below 1 Ω. This development has led to an increased safety risk during defective operations.
When there is a defect, such as a short circuit in the speaker chassis or on the crossover,
it is possible that the power amplifier --- despite existing protective switches --- will not
shut off. Long cable lengths and contact resistance on the plug connections may already
have an electrical resistance of 1 Ω. As a result, the power amplifier cannot ‘‘recognise’’
the operations as being defective and, therefore, delivers unacceptable high currents. In
the worst-case scenario, this may lead to fire damage (hot and charred wiring / connectors as a result of overloaded conductors and connectors, etc.).
regulations are lagging behind this development and are thus not up-to-date with this
modern technology.
In order to give consideration to this development, Kling & Freitag now equips its subwoofer systems with short circuit fuses at the signal input. These fuses do not offer
protection for the speaker, but do reduce the risk of consequential damage in the case
of a short circuit.
The current safety
For systems, which are not serially equipped with a short circuit fuse, Kling & Freitag
offers simple add-on kits so that you can adapt your existing subwoofer systems to the
current power amplifier development.
7.2 Identifying the Models with Short Circuit Fuses
The subwoofer systems, which are serially equipped with, fire safety fuses can be identified as follows; both mentioned stipulations must be fulfilled:
Adobe Systems
POWER: 700W
The first two
digits must be at
least 25.
XO-ON OFF
IMP: 6
SER.-NO.:
2 50 80 0 0 0 0 70
WT: 51,5kg
The next two
digits must be at
least 08.
All subwoofer systems, which are not serially equipped with short circuit fuses, can be, if
required, easily and inexpensively upgraded even by yourself.
An instruction manual for this upgrade is delivered with the add-on kit.
7.3 Specification of the Fuses
The fuses in all models have the following identical specifications:
Bussmann S 506
Bussmann S 506----8A slow
Bussmann S 506Bussmann S 506
8A slow
8A slow8A slow
When necessary, these fuses may only be replaced with the aforementioned original
fuse.
7.4 Replacement and Positions of the Short Circuit Fuses
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 disassembly of the chassis is, therefore, unavoidable.
7.4.1 Subwoofers without Crossover (XO)
The fuse holder of the subwoofers without a crossover (XO) is mounted on the signal
wiring behind the input connector. The subwoofers with two chassis have 2 fuses because the chassis are intended for parallel use.
When replacing the fuse, the chassis must be removed in order to reach the fuse holder.
Unscrewing the connecting terminal does not enable you to reach the fuse holder.
When the chassis is re-assembled, first loosely fasten the screws diagonal from one
another, then tighten them. By tightening the screws diagonally in two steps, a deformation of the chassis and thus a possible de-centring of the voice coil can be avoided.
7.4.2 Subwoofers with Crossover (XO)
The fuses of the subwoofers with a crossover are serially mounted on the crossover. The
exact position is described in the chapter ‘Internal Wiring of Subwoofers with Low-Pass Filter (XO)’ beginning on page 25 for the particular models.
If it happens to be a model, which has already been upgraded, then the fuse holder is
mounted on the signal wiring behind the input connector.
When replacing the fuse in both cases, the chassis must be removed in order to reach
the fuse holder. Unscrewing the connecting terminal does not enable you to reach the
fuse holder.
When the chassis is re-assembled, first loosely fasten the screws diagonal from one
another, then tighten them. By tightening the screws diagonally in two steps, a deformation of the chassis and thus a possible de-centring of the voice coil can be avoided.
7.5 Add-On Kits for Subwoofers without Short Circuit Fuses
All subwoofer systems, which are not serially equipped with short circuit fuses, can be, if
required, easily and inexpensively upgraded even by yourself.
An instruction manual for this upgrade is delivered with the add-on kit.
Subwoofers with a crossover that are not serially equipped with short circuit fuses can
also be, if necessary, upgraded with fire safety fuses. The crossover does not need to be
replaced. For this, we offer an add-on kit that is mounted between the crossover input
and the input connector.
The Speaker is equipped with two parallel-wired Speakon connectors.
Before connecting your speaker as shown in chapter 9 be sure to switch off all connected appliances and turn down all level controls.
− We recommend the use of high-quality speaker cables provided by KLING & FREITAG.
− For connections from the mixing console to the power amplifier inputs, please use 2-
pin shielded microphone cable with high-quality connectors.
− Avoid ground loops (see chapter 8.2 Avoiding Ground Loops)
− Please pay attention to the respective pin diagrams in this manual!
− Make sure that the +/- polarity between speaker and amplifier is correct. When simul-
taneously using power amplifiers from different manufacturers, be sure to use the
correct specific pin configuration. It may be necessary to modify the pin configuration
on the power amplifiers or on the connectors leading to them.
− To avoid loss of power, the cables should have a minimum wire gauge of 2.5 mm² -
more for longer cabled distances. A minimum wire gauge can be easily calculated
with the following formula:
Important
Minimum Wire Gauge (mm²) =
Required Cable Length (m)
2 x Speaker's Impedance (Ω)
If several loudspeakers are to be connected, the signal can be linked through from one
loudspeaker to the next. Please make sure that the total impedance of the loudspeakers
R(Ω) is not lower than the minimal impedance indicated on the power amplifier.
1/R1 + 1/R2 + 1/R3 + ... = 1/R
total
8.1 Connecting the Speakon Connectors to the Connecting Ter-
Every component of a P.A. or Hi-Fi System has its own internal 0V reference (ground). This
point is often connected to the protective earth connector (PE / Ground). If two or more
units are connected to one another with a line level audio cable, there may be a ground
connection through the ground of the power supply cable (yellow-green) as well as
through the shielding of the audio cable. The voltage difference between these two
ground points causes audible interference to come from the speaker.
8.2.2 Avoiding Ground Loops
If there is a loud humming or buzzing after the speaker has been connected, then check
that a ‘ground loop’ has not been built into the system. Some power amplifiers and
system controllers facilitate a ground lift switch. Set these ground lift switches to the
‘Lift’ position one after the other. If the noise is still audible, check if,
1. the noise is caused by a ground loop before the power amplifiers or controllers
(e.g. mixing console, effects or equalizers).
2. the system or parts of the system are connected to an ‘unclean’ power supply meaning one which is also running large motors or lighting systems. An ‘unclean’ supply voltage, electrostatic and electromagnetic fields can cause interference.
Please observe the following basic rules:
− Never!!! try to avoid a ground loop by disconnecting or taping the protec-
tive earth contact at the mains connector! Extremely dangerous! Extremely
dangerous!
− If possible, only use high-quality audio appliances with balanced signal outputs and
with power cables with PE connectors.
− Use high-quality cables with good shielding.
− The point of ground for all connected components should merge at one central
point. The power connections should lead out in a radial manner from one point
and not be linked from one unit to the next.
− When installing appliances that create strong electrostatic or electromagnetic fields
(large transformers, switch-mode power supplies), maintain some distance from
other audio appliances. In extreme cases, the only solution is to create a completely
independent ‘audio ground’; in other cases, it is sufficient to connect a filter in front
of the audio equipment.
9.1 Operating the Systems without K&F System Controller
The K&F subwoofers with integrated crossover (SW 112 - XO / SW 115D - XO or SW
118E - XO) can be combined with K&F top speakers by simply connecting them in parallel.
9.1.1 ‘XO ON’ Subwoofer with optional Crossover (XO)
In this mode of operation you can easily realise applications, where a higher bass level is
needed.
Important
Be sure to use only amplifiers, which can handle speaker impedances down to 3 Ω in
this mode.
When using the mid-high systems in a cluster (speakers in close proximity), reduce the
frequencies below 300 Hz by 3-4 dB!
Recommended combinations of CA systems, as described here, with K&F subwoofers:
2 CA systems + 2- 4 x SW 112-XO
or + 2 x SW 115E-XO
or + 1 - 2 x SW 118E-XO

The switch XO on the connecting terminal of the subwoofer must be at ‘ON’ for this
mode of operation:
For optimal performance and operating safety we recommend using a K&F System
Controller. Instructions for use, connecting diagrams and detailed descriptions of the
latest controller models ‘CD 24’ and ‘CD 44’ you can find in the corresponding user’s
manuals.
10. Operating the Speakers
− Switch off all equipment and turn down all level controls.
− Wire your subwoofer systems.
− Please pay attention to the user’s manual of your power amplifier!
− Upon completing the wiring, ensure that the connected speakers are working in
phase. To do so, use i.e. a phase checker. A phase error can also be recognized when
the connected channels are used simultaneously. During simultaneous use the bass
frequencies become notably quieter or the mid-frequencies such as voices cannot be
located.
− Now switch on the peripheral equipment first (mixing console, effects etc.), followed
by the K&F System Controller and lastly the power amplifiers. Always use the before
mentioned switching order. Otherwise switching noises may damage the system.
− If there is interference, turn off all appliances in the reverse order and check all cable
connections (see chapter 8.2 , Avoiding Ground Loops).
− Successively turn up the individual power amplifier channels and send a signal
with low volume to the system. Check to see if the desired signals are applied to
the intended speakers and make sure there is no interference. Make sure everything works properly, i.e. if the signals come from the correct speaker paths (high
signals from the tweeters, bass signals from the bass speaker). Your system should
now be ready for operation.
12.Touching Up Damage to Paint / Changing the Front Foam
Although the PU structured paint used by KLING & FREITAG is extremely resistant, we
recommend using protective covers or cases to help avoid damaging the paint during
i.e. continuous mobile use. If paint damage occurs despite these precautions, it can be
touched up by using commercial acrylic paint in the appropriate RAL colour of the
speaker. 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.
