3. Safety Instructions
3.1 Mounting the Speakers / Wall and Ceiling Installation
Warning
Have all installation works including suspension as well as wall or ceiling mount performed
by qualified event technicians or appropriately trained persons.
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.
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.
Fixed installations (stationary):
• For fixed installations without a safety element, secure the long nut and the M10 nut
from loosening. You can do this by using threadlocking adhesives or sealants.
Mobile installations (non-stationary):
• Always secure the speaker with a second independent safety device to prevent falling.
• To do so, use an approved safety rope with a 5 mm quick link on the safety eyebolt of
the speaker enclosure. You can get an appropriate quick link available as an accessory
from KLING & FREITAG.
3.2 Instructions for Speaker Placement
Caution
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 the 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.
The stability of stacked systems (also valid for the use of stands and distance rods!) is
contingent upon the following stability requirement:
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.

3.3 Preventing Hearing Damage
Caution
Keep your distance from operating speakers. This equipment is capable of delivering sound
pressure levels in excess of 90dB SPL, which may cause permanent hearing damage.
3.4 Protecting the Speakers/Reliability
Never feed audio at excessive levels to the speaker. Mixing consoles, equalizers, effect
units, etc. can produce clipping; excessive levels are normally visible on meters and through
indicators. 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, be sure to lower the signal level once it sounds distorted.
Operations without CD 44 Controller:
• To protect the speakers from being destroyed and to avoid fire hazard, they should
only be operated with professional power amplifiers with a maximum rated output
power of 200 W @ 8 Ohm.
• If power amplifiers have power ratings lower than 100 W @ 8 Ohm, then it is
imperative that the amplifiers have clipping limiters. Alternately, you can also insert a
clipping limiter before the amplifier.
• To protect the loudspeaker from mechanical damage when high SPL is required a
highpassfilter of 24 dB/oct. at 60 Hz has to be inserted into the signal chain.
Operations with CD 44 Controller:
• For optimal performance and operating safety of the SONA 6 speakers we recommend
using the system controller K&F CD 44.
• When operating the loudspeaker with amplifers without clipping limiter and nominal
amplifier power less than 100 W requires to set a Limit Reduction of 3 dB for the K&F
CD 44 controller. You can find more detailed information about this option in the
K&F CD 44 hardware user's manual.
• The destruction of speakers and the risk of fire as a result of a very rare power
amplifier or speaker defect may not be avoided by the controller in any case.
For damage caused by
• overloading the speakers or
• using power amplifiers with other than the recommended maximum output power
we do not assume warranty and excludes liability for possible consequential damage.
Signals that may damage the speakers include the following:
• clipping power amplifiers
• Continuous high-volume signals at high frequencies, continuous audio feedback
• Continuously distorted signals at high levels
• Sounds occurring when connecting, disconnecting, or switching on a device on the
audio system while the speaker is on
Never place your speakers
• where they are permanently exposed to direct sunlight,
• where the devices are exposed to high moisture or rain.
• where they are exposed to strong vibrations or dust.

Avoid damage caused by the speakers' magnetic fields
Even when not connected, loudspeakers continuously produce a magnetic field. Therefore,
during transport and placement of the speakers, it is important to ensure that there is a
sufficient distance between the speakers and magnetic data media and computer/video
monitors (except flat panels).

4. Wall and Ceiling Installation
4.1 Required Tools
• T25 Torx key
• 16 mm spanner (only black version)
• 17 mm spanner (2 x for white version)
• Mounting accessories for installation on walls or ceilings
4.2 Temporary alignment of the speakers
Tip
Loosen one or two of the three Torx
srews only. This way you can avoid
having to tighten an screw that got
covered by the Mounting Arm while
you aligned the speaker.
Loosen this screw(s) just enough so that
you can move the Mounting Arm with
some resistance. This will simplify the
final alignment of the speaker. This
will simplify the final alignment of the
speaker.
Align the loudspeaker arm as desired, and
then retighten the Torx screws that you
previously loosened.
Tighten the screws enough so that
the speaker reliably keeps its position.
Using excessive force to tighten
the screws can result in irreparable
destruction of the threads!

4.4 Wall Mounting of the Speaker
Warning
If people can move freely under the hung speaker, you must secure the speaker with a safety
element. The BGV (government safety organisation) C1 can only be fulfilled when using such
a safety device. Only when this regulation has been adhered to may the speaker be hung
over people and operated.
Without this securing, the safety level corresponds to DIN 18800.
1. As an alternative to the mounting plate, you can also mount the Mounting Arm with
other suitable 10 mm bolts. Make sure that you do not extend the lever arm of the wall
mount.
Screw the mounting plate onto
the wall or ceiling using all four
mounting holes. Choose fasteners
that are suitable for the wall or
ceiling material. After installation,
the mounting plate incl. speaker
must be capable of carrying the
6-fold of its own weight. Take
suitable measures to prevent the
screw connection from loosening
itself.
2. Attach the speaker so that the
ends of the threaded rods come in
contact.
3. Turn the long not onto the bolt of
the mounting plate by hand until
it touches the wall plate. Tighten it
slightly using a 16 mm spanner.
4. Screw in the counter nut M10 with
a 17 mm spanner against the long
nut while holding the long nut
tight with a 16 mm spanner.

5. The speaker is now completely
mounted and connected tightly to
the wall.
Now adjust the speaker.
To do so, loosen the screws at the
ball joint arm, as described on page
9.
5. Stand Installation
To mount a SONA 6 speaker on a stand, you need the accessory Stand socket M10.
1. For stand mounting, you do not need the provided long nuts. Unscrew them from the
mounting arm and keep them for possible later use.
2. Turn the counter nut entirely onto
the thread of the mounting arm.
Place the stand adapter M10 on
the mounting arm and turn it just
before the counter nut.
3. Screw in the counter nut M10
against the [...] using a 17 mm
spanner.
4. Loosen the clamp screw on the
stand adapter and place the
speaker with the stand adapter
onto the top end of the stand.

User's Manual K&F SONA 6
KLING & FREITAG GMBH © 2018 Version 5.9 Page 13 of 22
5. Make sure that the stand pole in
the stand adapter reaches up to
behind the clamp screw.
Tighten the clamping screw.
The speaker is now securely
connected to the stand. Now adjust
the speaker.
6. Proper Alignment of the Loudspeakers
Note that precisely targeted speaker systems can significantly improve the acoustic result. It is
not possible to make generalities about the alignment of specific systems because the room
has a substantial influence on the signal and the audible result.
As a rule, the mid- and high-transducers of loudspeakers should be mounted above the
audience's face value, so that the sound distribution cannot be shadowed.
In many cases it is advisable to mount a loudspeaker higher, so that the sound will be
distributed throughout the room more evenly. Low standing systems result in a greater
difference in volume between front and back seats than higher standing systems.
To simulate the correct alignment of the speakers beforehand, there are various programs
such as ‘EASE’ or ‘Ulysses’. On the homepage www.kling-freitag.de, KLING & FREITAG
provides the simulation data for the speakers to be downloaded.

7. Wiring
Warning
Speaker-signal currents are potentially hazardous to the human body.
When the system is in use, make sure that the connectors are secured against inadvertent
touch.
Always fully insert bared wire ends into the push connector or the Phoenix plug such that
bared parts of wire can not be touched.
For speakers with Phoenix connector the bared wire ends have to be accurately screwed into
the plugs.

manual of the CD 44! This applies for use with and without the K&F Subwoofer.
7.3 Wiring Instructions
• Before connecting your K&F SONA 6 speaker, switch off all devices and turn down all
faders and encoders.
• Be sure to use high-end speaker cables with an appropriate wire gauge. Select the wire
gauge with regard to the cable length.
• To connect the mixing console to the power-amp inputs, use shielded 2-pole balanced
microphone cables equipped with quality connectors.
• Avoid creating ground loops.
• Be sure to follow the pinouts shown in this manual.
• Check for correct polarity of the speaker links to the power amplifier. When using
amplifiers by different manufacturers, make sure the pinout is correct. If necessary,
consider modifying the amplifier or connector pinouts as required.
• Upon completing wiring, ensure that the connected speaker channels are working
in phase, for example, using a phase 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.
• When connecting multiple speakers, you can daisy-chain the signal from one speaker to
the next. Make sure that the total impedance of all speakers connected to an amplifier
does not fall below the minimum impedance specified for the amplifier. 1/R1 + 1/R2 + 1/
R3 + … = 1/Rtotal
8. Initial Operation

User's Manual K&F SONA 6
KLING & FREITAG GMBH © 2018 Version 5.9 Page 15 of 22
• Switch off all devices and turn down all volume controls on the mixing console and the
amplifiers.
• Wire the SONA 6 systems.
• Switch on the devices in the following order: first the mixing console, then the
controller and finally the power amplifiers! Be sure to observe this power-up sequence
at all times. Failing to do so may result in switch-on noise that may damage your
system.
• If you hear noise, turn off all devices in reverse order, then check all cable connections.
• Turn up all amplifier channels one after another and output a low-volume signal to the
system. Check whether the audio is properly routed to the appropriate speakers. Make
sure no noise is heard through those speakers.
Controller operation: The SIGNAL indicators of the CD 44 controller will light when the
output level exceeds –45 dB. Your system is now ready for operation.
• With amplifiers with insufficient input-stage headroom, you may not always be able
to prevent distortion by reducing the power-amp volume controls. In this case, the
clipping indicator may not light when clipping actually occurs! To prevent damage to
the speakers, we recommend fully turning up the power-amp volume controls, then
carefully turn up the volume on the mixing console or controller or reduce the limiter
threshold of the controller as appropriate in order not to overload the amplifiers.
• When turning off the system, first turn down the amplifier input controls. Next, power
down the amplifiers, then turn off the remaining devices.

9. Directions for the 100 volt connection.
KLING & FREITAG speakers with '100 V' option are fitted with high-quality transformers. This
serves to minimize loss of sound. Highly professional sound reinforcement results can be
achieved using '100 Volt' KLING & FREITAG speakers.
Reasons for choosing Speakers with 100 Volt Transformers:
• Reduction in conduction loss.
• Easy installation 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 Volt amplifier.
• Speakers are galvanically isolated.
• Speakers can be integrated into existing 100 Volt systems.
