3. Safety Instructions
3.1 Mounting the Speakers / Wall and Ceiling Installation
Warning
Suspended loads pose a safety risk.
Only qualified technicians are permitted to perform the installation steps. Be sure to use
personal protective equipment at all times.
The technicians installing the speaker on site are responsible for and guarantee safe setup
and use.
Never use signal cables or power cords for suspending, aligning, or securing the systems.
Before installing, check the stability, strength, and materials of walls, ceilings, and boarding.
For example, use suitable rawlplugs for wall panels and make sure the strength is sufficient.
Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or
chain hoists) must comply with the DGUV regulations 17 and 18 or similar locally applicable
accident-control standards. The maximum load must have been certified by an authorized
expert.
Be sure to tighten all bolts and screws to the specified torque.
Unless otherwise stated, use only KLING & FREITAG original parts for mounting the speakers.
Never use other parts (in particular, parts not made by KLING & FREITAG).
Make sure all fittings used are suitable for the task at hand and meet all relevant safety
requirements.
Ensure that all connections are secured against coming loose and that only authorized,
statically tested and correctly sized supports, mounting equipment, wire ropes and chains are
used.
Be sure to always visually inspect all safety-related speaker and accessory components
before use. If there are signs of wear, cracks, or deformation, etc., replace the affected parts
immediately. Visual inspection also includes checking all screwed connections of supporting
components.
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
3.2 Notes for Mounting the Speakers
Warning
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall.
Note that speakers can move as a result of vibrations. To prevent them from falling from
their mounted position, they must be secured properly.
Run the cables in a way that nobody can trip over them.
3.3 Preventing Hearing Damage
Caution
Keep your distance from operating speakers. This equipment is capable of delivering sound
pressure levels in excess of 90 dB SPL, which may cause permanent hearing damage.
3.4 Protecting the Speakers / Operating Safety

User's Manual K&F SCENA 15
KLING & FREITAG GMBH © 2017 Version 1.7 Page 8 of 21
SCENA 15 speakers may only be used in combination with a K&F SystemAmp/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 or
• using the speakers without K&F SystemAmp/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. Suspending the Speakers
With the help of the M8 x 20 eyebolts available as accessories from KLING & FREITAG, the
SCENA 15 can be suspended
Screw in at least two of these eyebolts into the existing M8 threads on the sides.
Suspend the speaker with the help of shackles and steel ropes.
Warning
Ensure that all connections are secured against coming loose and that only authorized,
statically tested and correctly sized supports, mounting equipment, wire ropes and chains are
used.
Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or
chain hoists) must comply with the DGUV regulations 17 and 18 or similar locally applicable
accident-control standards. The maximum load must have been certified by an authorized
expert.
It is not permissible to suspend anything else from the bottom of the SCENA 15.

5. Rotating the high frequency horn
By default, the SCENA 15 has a coverage angle of 50°x70° (hor. x vert.). When you use it as a
stage monitor, you have a good coverage into the depth of the stage and an optimal lateral
sound field boundary on the stage. When used on a speaker stand, the practice-orientated
directional characteristic of 70°x50° (hor. x vert.) results automatically. For special uses, the
horn can also be rotated.
Required tools:
• 3 mm Allen key for loosening the front grille
• 4 mm Allen key for loosening the horn tweeter
If you wish to rotate the horn, proceed as follows:
A
B
D
C
1. Remove the grille screws (A) with a 3 mm Allen key and remove the front grille.
2. Remove the horn screws (B) and the chassis screws (D) opposite them with a 4 mm Allen
key.
3. Remove the horn.
4. Remove the spacer tubes (C) that are located under the mounting tabs.
5. Place the spacer tubes (C) under the mounting tabs of the new position.
6. Turn the horn by 90° and put it in place while making sure that the socket of the horn is
in the middle of the woofer and securely latches into the groove.
7. Screw on the horn tightly again using the longer horn screws (B).
8. Screw in the shorter chassis screws (D) again.
9. Mount the front grille with the 8 grille screws.

6. Wiring Instructions
• Before connecting your SCENA 15 loudspeaker switch off all equipment and turn down
all level controls.
• Only use high-quality speaker cables with a sufficient wire gauge. The wire gauge
depends on the length of the speaker cable.
• For connections to the power amplifier inputs, use 2-pin shielded microphone cable
(balanced) with high-quality connectors.
• Avoid creating ground loops.
• Be sure to note the pinouts shown in these user's manual.
• Make sure that the +/- polarity of the speakers at the amplifier is correct. When
simultaneously 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.
• Upon completing wiring, ensure that the connected speaker channels are working
in phase, for example, using a voltage tester. When the connected channels are used
simultaneously, you can identify out-of-phase statuses by bass cancellation or mid-
frequency signals (e.g. voices) that cannot be located properly.
• If several loudspeakers are connected, the signal can be linked through parallel from
one loudspeaker to the next. Make sure that the total impedance of the loudspeakers
R(Ohm) is not lower than the minimal impedance indicated on the power amplifier. 1/
R1 + 1/R2 + 1/R3 + ... = 1/Rtotal
7. First-time Use
• Switch off all equipment and turn down all level controls of the mixing console and the
power amplifiers.
• Wire your SCENA 15 systems according to the instructions in these user's manual.
• Switch on the mixing console first, then the controller and the power amplifier. Always
use the before mentioned switching order. Otherwise switching noises may damage the
sound system.
• If there is interference, turn off all appliances in the reverse order and check all cable
connections.
• Successively turn up the individual power amplifier channels and send a signal with low
volume to the system. Check whether the audio is properly routed to the appropriate
speakers. Make sure no noise is heard through those speakers.
With controller: The SIGNAL LEDs of the CD 44 Controller will light up if the output
level is higher than -45 dB. Your system should now be ready for operation.
• Turning down the input level controls may not always prevent distortions in the input
section of the power amplifier, especially if this section has a relatively low headroom.
A clipping signal may not be displayed by the clipping indicator then! To prevent signal
interruptions or damages to the speakers, turn the level controls of the power amplifier
to the maximum position, if possible. Set the output level of the mixing console or the
controller to a level that doesn't overload the power amplifiers or decrease the limiter
threshold of the controller.
• When turning off the system, the input controls for the power amplifiers should be
turned down first followed by the power switches of the amplifiers. After that, the
other appliances can be turned off.

8. Configuration and Connecting Diagram
8.1 1 Channel Mode
To avoid unnecessarily assigning controller channels, this operating mode is recommended for
most usages.
In 1 channel mode, the high frequency driver and the low/mid-range chassis are controlled
by one controller channel. The internal crossover takes over the frequency separation for
tweeter and low/mid-range.
In 1 channel mode, a maximum sound pressure of 134 dB SPL is reached.
In general, this sound pressure level is fully sufficient for use as a stage monitor.

KLING & FREITAG GMBH © 2017 Version 1.7 Page 13 of 21
8.2 2 Channel Mode
You can use the 2 channel operating mode when you have to slightly increase the maximum
sound pressure level.
In 2 channel mode, a maximum sound pressure of 136 dB SPL is reached.

14. Care and Maintenance
1.
Warning
For the owner and user, it is mandatory to be aware of the safety relevance of speakers
that can be flown.
Note that the mains cable is supplied with either a connector appropriate for the place
of delivery (see item number) or with open terminals (on the mains side).
The SCENA 15 system can exhibit signs of wear over the years, for example, from
mechanical strain, transport damage, corrosion, or improper handling. Remember that
flying speakers always impose a high safety risk.
Generally, perform a visual inspection of your speaker every time you suspend it or take
it down. SCENA 15In fixed installations, check the speaker for signs of wear at regular
intervals.
When performing those checks, particularly look for deformations, cracks, dents, damage
to threads, and corrosion. Also check slings and lifts (e.g. shackles, chains, and steel
ropes) carefully for wear and deformation.
If as a result of these checks any uncertainty should arise with regard to safety or defects
are found, don’t use the speaker any longer. SCENA 15If defects are ascertained, then
you must send in the product to KLING & FREITAG GmbH for inspection and repairs, if
necessary.
Inspection regulations may vary depending on application and country of use. Observe
all applicable regulations; when in doubt, contact the local authorities.
Many countries require regular inspection of mounting components and accessories. An
additional annual inspection is typically required to be performed by a technical expert.
Moreover, a legally certified or official authority must perform a detailed inspection
every four years.
Therefore, be sure to maintain an inspection log. Enter the values determined for each
speaker and accessory during the periodic checks into this log. This way, relevant data
are always at hand in case of inspection. The log should also document maintenance
measures and inspection intervals and contain parts lists.
2. Twice a year, turn on the switch in the speaker’s connector area so that it stays functional.
3. The Polyurea synthetic coating used by KLING & FREITAG is impact proof and highly
resistant. We recommend using protective coverings or transport cases to help avoid
damaging the paint in case of continuous mobile use, etc.
4. 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.

User's Manual K&F SCENA 15
KLING & FREITAG GMBH © 2017 Version 1.7 Page 19 of 21
15. Transportation and Storage
The SCENA 15 is protected against short-term moisture. despite, be sure to store, transport,
and use the accessories in dry environments only. The SCENA 15 System is not designed for
long-term use in a corrosive environment.
Make sure that the system is adequately ventilated during longer storage periods so any
residual moisture can escape from the equipment.
Furthermore, you should ensure that the SCENA 15 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.
16. Disposal
Recycle the packaging material of the device.
