Safety Instructions

Mounting the Speakers / Wall and Ceiling Installation
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.
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.
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.
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 user’s manual. See chapter Configuration and Connecting Diagram from page 12.

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 amplimers 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 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. 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).

Correct Ratio between Top and Subwoofer

For a balanced sound reproduction, suitable for speech and average music material, one subwoofer SONA SUB II can be combined with up to 4 tops SONA 5. This is valid as long as the amplifiers for subwoofer and top skeakers have the same overall gain and the SONA SUB II 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, then the subwoofer can used with 2 SONA 6 speakers or 1 SONA 8 speaker. For this type of use, the subwoofer has to be used with filtering, since there is a risk of mechanical otherwise. For maximum performance and operating safety, select use with the CD 44. For maximum performance and operating 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 theexcitation 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 setup location, the spatial geometry, the required playback material and, last but not least, your personal 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.

Level increase because of adjacent areas
As shown in the following table, adjacent areas can lead to significant level differences.

Setup Location	Name	Level increase	Pictogram
Freely suspended	Free field (full space)	+/- 0 dB

On a surface (Reference use)| Half space| ca. +3 dB to +6 dB|

In a space boundary| Quarter space| ca. +6 dB to +12 dB|

In a corner| Eigth space| ca. +9 dB to +18 d|

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.

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. Without the Phoenix plug, the Phoenix connector’s contacts have hazardous contact voltage!
Wiring Instructions

Before connecting your SONA SUB II 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, please 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 midfrequency 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. Please 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

First-time Use

Switch off all equipment and turn down all level controls of the mixing console and the power amplifiers.
Wire your SONA SUB II 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.
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.
