2. Product Description
The subwoofer SONA SUB II is the ideal bass supplement for K&F SONA speakers. With its
discreet appearance, 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. SONA-Lautsprecherserie

2.3 Required signal processor
The following information does not apply to the option "XO" :
When using the SONA SUB II, a signal processor is required such as an electronic crossover or
the K&F Controller CD 44.
The signal processor must provide at least the following settings:
• 1 x high-pass 4th order
• 1 x low-pass 4th order
• 1 x bell filter

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 or similar locally applicable accidentcontrol 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.
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.
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
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 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.
Operations without CD 44 Controller (only option "XO"):
• 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 150W@8Ohm.
• If power amplifiers have power ratings lower than 75W@8Ohm, then it is imperative
that the amplifiers have clipping limiters. Alternately, you can also insert a clipping
limiter before the amplifier.
• To achieve sensible acoustic results and to protect the speaker from mechanical
destruction during use, the speaker must be filtered according to these operating
instructions. See chapter Configuration and Connecting Diagram from page 10.
Operations with CD 44 Controller:
• For optimal performance and operating safety of the SONA SUB II 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@8Ohm requires to set a Limit Reduction of 3 dB 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 or
• 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 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.
