Protecting the speakers / avoiding fire hazard

In general, audio signals should 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.

 To protect the speakers from being destroyed and to avoid fire hazard, they should only

be operated with professional power amplifiers with the following specifications:

− Integrated or preceding subsonic filter (approx. 20 Hz, min. 12 dB / octave)

− integrated clipping limiter

− maximum rated power 250W@16Ω (equivalent 1000W@4Ω)

 If you wish to use a speaker with a power amplifier which does not fulfil these specifica-

tions, then the speaker should be controlled using a Kling & Freitag system controller with limiter function. This is the only way overloading and that the risk of fire can be avoided. The results of such a power amplifier defect of cannot be avoided by the controller.

 If power amplifiers have power ratings lower than mentioned above, then it is imperati-

ve that a clipping limiter is used to protect the speaker even if it is used with a Kling & Freitag system controller.

For damage caused by overloading or use with power amplifiers other than those recommended above, Kling & Freitag GmbH does not assume warranty and excludes liability for possible consequential damage.

User's Manual CA 106

The following signals may damage the speakers

− permanent high-pitched signals with high frequency and continuous noise from feedback.

−

permanently distorted signals with high power.

−

noises, which occur when the amplifier is on while equipment is being connected, disconnected or switched on

Important

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 operating. 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

Preventing hearing damage

To prevent the risk of hearing damage, avoid being too close to operating speakers, even if the volume level seems to be low enough. In general, volume levels over 90 dB can cause hearing damage

rosion with protective coating.

User's Manual CA 106

4. Instructions for Versions with ‘100 V’ Option

Kling & Freitag speakers are fitted with high-quality toroidal transformers. This serves to minimize loss of sound. Highly professional sound reinforcement results can be achieved using 100 V Kling & Freitag speakers.

4.1 Reasons for choosing Speakers with 100 V Technology

− Reduction in conduction loss.

− Easy assembly 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 V amplifier.

− Speakers are galvanically isolated.

Important

− Speakers can be integrated into existing 100 V systems.

4.2 Connecting Diagram of the 100V Speaker Inputs

The 100 V transformer for the CA 106 has 3 taps. These enable the speaker to be operated at 50 VA, 100 VA or 150 VA. Which tap is connected to which pin can be seen below.

5. Instructions for Suspending the Speakers

The speakers may only be suspended by trained specialised personnel. Please follow the accompanying safety and assembly instructions carefully as

well as the required safety factors. Pay attention to the corresponding national safety regulations.

Speaker systems, whether single or connected to one another, must always be secured to a second separate point.

Ensure that all connections are secured to prevent their detaching on their own and that only admissible statically tested and sufficiently sized connecting devices, ropes and chains are used.

The M6 threads may only be used in combination with the speaker mount ‘Omnimount 50’.

A maximum load of 10 kg may be suspended from the two flying points (M8 thread inserts) of one Speaker. This means a maximum additional load of 5 kg on each flying point.

6. Coverage Angles of the CA 106 Speaker

The CA 106 can be operated in a vertical or horizontal (i.e. as a stage monitor) position. The coverage pattern of the speaker can be adapted to special needs by a 90° rotatable horn.

The table below shows the coverage angles of a standing speaker: To determine the coverage pattern of the high frequency horn, shine a flashlight through the front covering at the level of the horn. You will find a silver stripe that determines the position and thus the coverage angles of the horn.

DEFINITION:

6.1 Changing the Coverage Angles

To turn the horn, follow these steps:

1) Remove the two grille mounting screws on the top and bottom of the speakers

with a 2.5 mm Allen key and remove the grille from the speaker enclosure.

2) Remove the four screws from the high frequency horn (also using a 2.5 mm allen

key). Loosen the high frequency horn by using both hands, palms to the outside, to grasp into the horn and lift the horn with even pressure from the palms of your hands towards the outside. Never use a screwdriver or similar objects to reach behind the edge of the horn, as this could damage it.

3) Rotate the horn 90° and screw the horn on tightly again (do not force it!).

4) Screw the grille on tightly.

If the coverage angle needs to be changed often, make sure that the horn is not always rotated in the same direction, as the connecting cables, when twisted, may cause the contacts of the driver to become loose.

7. Mounting Instructions for Loudspeakers

Mount the speakers securely. To avoid injury or damage, always be sure to mount the speakers securely so that they do not fall. Speakers, which are stacked, must be secured with securing straps. When laying the connecting cables, make sure that nobody can trip.

The stability of stacked systems (also valid for the use of stands and distance rods!) is

Warning

contingent upon the following stability requirement. These conditions must, therefore, be guaranteed by the user:

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.

7.1 Proper Arrangement of the Loudspeakers

Be aware of the fact that the logical targeted alignment of this high quality speaker system can lead to a significant qualitative increase in 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.

Please note that this is only a general guideline and the best possible result may vary from room to room.

To simulate the correct alignment of the speakers beforehand, there are various programs such as ‘Ease’ or ‘Ulysses’. The Kling & Freitag speaker system data is available for download on our website www.kling-freitag.de.

The following graphics will assist in making a rough estimate as to the distance range of the CA 106. The graphics only take into consideration the sum of the direct sound and not the influence of the room. Because of this there can, in some cases, be noticeable deviation.

7.2 Arrayed Speaker Systems (Cluster)

If the loudspeakers are operated through the optional K&F C2 System Controller, we recommend turning on the ‘Top Low Cut’ switch for clustered operation. Thus the frequency response for this application can be optimised (see also K&F C2 User's Manual).

When operating the systems without the K&F C2 System Controller in a clustered configuration, the signal level of frequencies below 300 Hz should be reduced by 3-4 dB.

8. Wiring

The speaker is equipped with two parallel Speakon connectors. Make sure that all units are switched off and all controls are turned down before con-

necting your CA 106 systems.

− We recommend the use of high-quality speaker cables provided by KLING & FREITAG.

− For connections to the power amplifier inputs, please use 2-pin shielded microphone

cable with high-quality connectors.

− Avoid ground loops (see chapter 8.2 )

− Please pay attention to the respective pin diagrams in this manual!

− Make sure that the +/- polarity of the speakers at the amplifier is correct. When simul-

taneously 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 the wiring, ensure that the connected speaker channels are work- ing 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.

− To avoid loss of power, the cables should have a minimum wire gauge of 2.5 mm² - more for longer cabled distances. A minimum wire gauge can be easily calculated with the following formula:

Minimum Wire Gauge (mm²) =

Required Cable Length (m)

2 x Speaker Impedance (Ω)

If several loudspeakers are connected, the signal can be linked through from one loudspeaker 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:

8.2 Avoiding Ground Loops

Important

Warning

8.2.1 What is a Ground Loop?

Every component of a P.A. or Hi-Fi System has its own internal 0 V reference (ground). This point is often connected to the protective earth connector (PE / Ground). If two or more units are connected to one another with a line level audio cable, there may be a ground connection through the ground of the power supply cable (yellow-green) as well as through the shielding of the audio cable. The voltage difference between these two ground points causes audible interference to come from the speaker.

8.2.2 Avoiding Ground Loops

If there is a loud humming or buzzing after the CA 106 System has been connected, then check that a "ground loop" has not been built into the system. Some power amplifiers and system controllers are equipped with a "Ground Lift" switch. Set these switches to the "Lift" position one after the other. If the noise is still audible, check if,

Please observe the following basic rules:

− Never!!! try to avoid a ground loop by disconnecting or taping the ground

− If possible, only use high-quality audio appliances with balanced signal outputs and

− Use high-quality cables with good shielding.

− The point of ground for all connected components should merge at one central

− When installing appliances that create strong electrostatic or electromagnetic fields

9. Configurations and Connecting Diagrams

9.1 Operating the Systems without C2 Controller

The CA 106 systems can be used alone or in conjunction with a K&F subwoofer with integrated crossover (e.g. SW 112-XO / SW 115D-XO / SW 115E - XO or SW 118E-XO). In this mode of operation the crossover limits the subwoofer's frequency range.

 To protect the speakers from being destroyed and to avoid fire hazard, they should

only be operated with professional power amplifiers with the following specifications:

− integrated or preceding subsonic filter (approx. 20 Hz, min. 12 dB / octave)

− integrated clipping limiter

− maximum rated power 250W@16 Ohms (equivalent 1000W@4 Ohms)

 If you wish to use a speaker with a power amplifier which does not fulfil these spe-

cifications, then the speaker should be controlled using a Kling & Freitag system controller with limiter function. This is the only way overloading and that the risk of fire can be avoided. The results of such a power amplifier defect of cannot be avoided by the controller.

9.2 Operations with C2 Controller

By using carefully adjusted filters (EQ) on special system cards for the CA systems, the C2 Controller optimises feedback prevention and the frequency response of the speakers.

The controller provides optional bass boost in full-range mode, optimisation for cluster operation (Top-Low Cut switch), high boost and sub-mono function.

The C2 Controller optimises the operating safety of the speakers and power amplifiers by using special peak and RMS limiters in Sense Technology:

With other (universal) controllers, the gain of the selected power amplifiers must be known. The limiter on the C2 Controller, on the other hand, uses a special control circuit to determine the actual output voltage of the power amplifiers. The limiter then reduces the input level only when the power amplifier actually provides more power than the speakers can handle. The amplifier’s gain and the position of the input level control for the power amplifiers are insignificant for the limiter function of the C2 Controller.

If the wrong LED lights up or a wrong (i.e., in 2-way active mode, low signal from a high frequency speaker) or distorted signal occurs, then there is a mistake in the wiring.

− 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. The output level of the mixing console or the controller should be set to a level that doesn't overload the power amplifiers.

− 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.

− The crossovers of the CA 106 systems are equipped with protection circuits for the high frequency driver and the crossover itself. These circuits cut off the signal current when highly overloaded. If the high speaker turns off, reduce the volume. After a few seconds, it will turn back on automatically.

12. Touching Up Damage to Paint / Changing the Front Foam

Although the PU structured paint used by KLING & FREITAG is impact proof and extremely resistant, we recommend using protective coverings or cases to help avoid damaging the paint during i.e. continuous mobile use. If paint damage occurs despite these precautions, it can be touched up by using commercial acrylic paint in the appropriate RAL colour of the speaker.

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.

17. Regulations for Disposal

17.1 Germany:

It is not allowed to dispose of used electrical equipment as domestic waste.

But please do not All Kling & Freitag products are plain business-to-business (B2B) products. Disposal of

Kling & Freitag products labelled with a waste bin sign have thus to be disposed of by Kling & Freitag alone. Please call Kling & Freitag at the number stated below if you have a Kling & Freitag product to be disposed. We will offer you a straightforward and professional disposal not affecting costs.

If there is no dustbin sign on one of your Kling & Freitag products, because they have been sold before March 2006 then by law the owner is in charge of the disposal. For these we will be happy to assist and offer you proper ways of disposal.

Telephone number to call about the disposal of used Kling & Freitag products: +49 (511)-96 99 7-0

Explanation: With the ElektroG (law relating to electrical and electronic equipment and appliances)

we have complied with the EU-directive on waste electrical and electronic equipment (WEEE, 2002/96/EC)

The Kling & Freitag AG has thus labelled all products mentioned in the WEEE from 03/24/2006 onwards with a sign with a crossed out waste bin and a white bar below. This sign indicates that the disposal into the domestic waste is prohibited and that the product has been put into circulation at the 03/24/2006 earliest.

The Kling & Freitag GmbH has been legally registered as a manufacturer with the registration office EAR. Our WEEE Registration-Nr. is: DE64110372

For the German Registration office EAR we have accredited that our products are sole B2B products.

dispose of them at official collecting points for recycling either!

17.2 EU, Norway, Island, and Liechtenstein (not Germany):

It is not allowed to dispose of used electrical equipment as domestic waste.

The Kling & Freitag AG has thus labelled all products coming from EU-Member countries as well as Norway, Island and Liechtenstein (except Germany) mentioned in the WEEE from 08/13/2005 onwards with a sign with a crossed out waste bin and a white bar below. This sign indicates that the disposal into the domestic waste is prohibited and that the product has been put into circulation at the 08/13/2005 earliest.

Unfortunately the European directive WEEE has been complied with implementing different national provisions of law throughout all member countries, which makes it impossible for us to offer consistent solutions for the disposal throughout Europe.

Responsible for complying with these provisions of law is the local distributor (importer) of each country.

For proper disposition of used products in accordance with these local provisions in the mentioned countries of the European Union (except Germany) please ask your local dealer or the local authorities.
