2. Product�Description
The subwoofer SONA SUB is the ideal bass supplement for the speaker SONA 5. With its discreet ap-
pearance, it fits in nearly any architecture. The practical mounting points with a double keyhole design
enable wall and ceiling installation. In addition to possible use with the K&F Controller CD 44, it can
also be operated with a universal electronic crossover. This possibility makes it extremely attractive not
only because of its convincing performance but also economically.

3. Safety�Instructions
3.1 Mounting�the�Speakers�/�Wall�and�Ceiling�Installation
Warning
The speakers may only be mounted to wall and ceilings by qualified personnel.
The technicians responsible for assembling the speakers on site are responsible for the safe setup and
use of the speakers and guarantee this.
Never use signal cables or power cords for suspending, aligning or securing the systems.
Before carrying through ceiling and wall installations, it is essential to consider the load capacity of
walls, ceilings and panelling as well as the stability and type of the construction. If there is wall pan-
elling, for example, it is then necessary to examine the solidity of the wall and use the appropriate wall
plugs.
Make sure to comply with the stipulated tightening torques.
If not otherwise stated in this manual, only original KLING & FREITAG parts may be used for mounting
the speakers. The use of other parts - in particular parts by other manufacturers - is not permitted in
this case.
Ensure that all installation connections comply with the applicable safety guidelines and that the size
and strength are sufficient.
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.
As a basic principle, you must visually inspect mounted speakers at regular intervals. If there are signs
of wear, cracks, or deformation, then you must replace the parts immediately. The visual inspection al-
so includes checking the screwed connections on supporting elements.
The information described here does not relieve the user of the duty to follow the given safety require-
ments and legal regulations.
3.2 Notes�for�Mounting�the�Speakers
Caution
Mount the speakers securely. To avoid injury or damage, always be sure to mount the speakers secure-
ly 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.
3.3 Preventing�hearing�damage
Caution
Avoid beeing too close to operating speakers. This equipment is capable of delivering sound pressure
levels in excess of 90 dB/SPL, which may cause permanent hearing damage.
User's manual K&F SONA SUB
KLING & FREITAG GMBH © 2010 Revision 1.2 Page 8 of 21
3.4 Protecting�the�Speakers�/�Operating�Safety
Important
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 over-
loaded 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 over-
loading the input circuit. In any case, the signal must be reduced as soon as it sounds unnaturally dis-
torted.
Operations�without�CD�44�Controller:
• To protect the speakers from being destroyed and to avoid fire hazard, they should only be oper-
ated with professional power amplifiers with a maximum rated output power of 150W@8Ω.
• If power amplifiers have power ratings lower than 75W@8Ω, then it is imperative that the am-
plifiers have clipping limiters. Alternately, you can also insert a clipping limiter before the amplifi-
er.
• To achieve sensible acoustic results and to protect the speaker from mechanical destruction dur-
ing use, the speaker must be filtered according to this manual. See chapter [Configuration and
Connecting Diagram] from page 13.
Operations�with�CD�44�Controller:
• For optimal performance and operating safety of the SONA SUB 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 75W@8Ω requires to set a Limit Reduction of 3dB for the K&F CD 44 controller.
• 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
• using power amplifiers with other than the recommended maximum output power
we do not assume warranty and excludes liability for possible consequential damage.
The�following�signals�may�damage�the�speakers:
• clipping power amplifiers
• 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.
Avoid�damage�caused�by�the�speakers'�magnetic�fields
Speakers are permanently surrounded by a magnetic field, even when they are not connected. There-
fore, 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).

5. Correct�Ratio�between�Top�and�Bass�Speakers
For a balanced sound reproduction, suitable for speech and average music material, one subwoofer
SONA SUB can be combined with 2 tops SONA 5. This is valid as long as the amplifiers for SONA SUB
and SONA 5 have the same overall gain and the SONA SUB is mounted on a wall or on the open floor
(reference use).
If more bass level is desired for DVD playback or reproducing very low-frequency signals (i.e. motor
sounds), then the number of SONA SUB has to be doubled. For this type of use, the SONA 5 has to be
used with filtering, since there is a risk of mechanical otherwise. For maximum performance and oper-
ating safety, select use with the CD 44.
For an additional bass boost the level increase which occurs in room edges and room corners can be
used. The placement in room edges and room corners is also beneficial because of the excitation of
more room modes which results in a more even bass coverage across the room.
The correct loudness ratio between tops and bass is, therefore, very dependent upon the bass’s set-
up location, the spatial geometry, the required playback material and, last but not least, your person-
al preferences. For this reason, the ratio between tops and bass should always be assessed on site, for
example with a third-octave band analyser or a notebook with corresponding measurement software.

7. Wiring
Warning
Electrical current of loudspeaker signal may be hazardous for the human body.
Always make sure the connectors secured against touch when the equipment is in use.
When�using�the�Phoenix�connector:
To guarantee the protection against contact on the Phoenix connector, you may only use the provided
4-pin Phoenix plug. This is also the case even if you only use two of the Phoenix connector’s pins.
Always fully insert bared wire ends into the Phoenix plug such that bared parts of wire can not be
touched.
The bared wire ends have to be accurately screwed into the plugs.
When�using�the�Speakon�connector:
The Phoenix connector is connected in parallel to the Speakon connector.
To guarantee protection against contact on the Phoenix connector, the provided 4-pin Phoenix plug
must be plugged in during use. This is also the case even if you just use the Speakon connector. With-
out the Phoenix plug, the Phoenix connector’s contacts have hazardous contact voltage!
7.1 Wiring�instructions
Important
• Before connecting your SONA SUB 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.
Minimum�Wire�Gauge�(mm²)
=�Required�Cable�Length�(m)�/�(2�x�Speaker�Impedance�(Ω))
• For connections to the power amplifier inputs, please use 2-pin shielded microphone cable (bal-
anced) with high-quality connectors.
• Avoid ground loops.
• Please pay attention to the pin assignments shown in this 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 con-
figuration. It may be necessary to modify the pin configuration on the power amplifiers or on
the connectors leading to them.
• Upon completing the wiring, ensure that the connected speaker channels 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.
• If several loudspeakers are connected, the signal can be linked through parallel from one loud-
speaker 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.

KLING & FREITAG GMBH © 2010 Revision 1.2 Page 17 of 21
8. Operating�the�Speakers
Important
• Switch off all equipment and turn down all level controls of the mixing console and the power
amplifiers.
• Wire your SONA SUB systems according to the instructions in this 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 connec-
tions.
• 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.
• 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 possi-
ble. 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.
