1. General Instructions for Using Speakers

Mounting the speakers

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 safety straps. When laying the connecting cables, make sure that nobody can trip.

Suspending as well as mounting the speakers to walls or ceilings must be carried out by qualified personnel. The speakers must be hung by using at least two of the five designated flying points.

Never use signal cables for suspending or securing the systems. The same applies when lifting and aligning the speakers.

Never hang more than two speakers under one another without using the designated Kling & Freitag mounting devices.

Ensure that all installation connections comply with the applicable safety regulations and that the size and strength are sufficient. Further instructions are in our user's manual for assembly equipment and in the general safety instructions for speakers and assembly equipment.

For mobile and fixed installations, use only assembly equipment from KLING & FREITAG. Make sure to observe the installation instructions and safety notes shown in the user's manual for assembly equipment. Mounting equipment and speakers must be visually inspected on a regular basis. At any sign of wear, fittings should be replaced immediately. Furthermore, all screwed connections should be checked regularly.

Warning

Do not Install Speakers in any of the Following Places:

− Where the speakers are permanently exposed to direct sunlight

− Where the speakers are exposed to high moisture

− Where the speakers 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.

Protecting the Speakers

When selecting power amplifiers, ensure that they have a sufficient power level. Power amplifiers with an output level, which is too low, can cause the speakers to overload (clipping). Power amplifiers should never be overloaded. When the nominal power of the power amplifiers is higher than that of the speaker, overload may ruin the speaker. The input section of a power amplifier may be overloaded without displaying a clipping signal, e.g. if the headroom of this circuit is too low. We recommend turning the level controls to the maximum position and to adjust the level before the amplifiers.

Important

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.

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.

3. Instructions for Suspending the Speakers

Only trained personnel should suspend speaker systems. Speaker systems, whether single or connected to one another, must always be secured to a second separate point, even if two rigging points are used for suspending the speaker system!

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.

Pay attention to the required safety factors. Please follow the accompanying safety and assembly instructions carefully as well as the corresponding national safety regulations.

A maximum load of 50 kg may be suspended from the two Ancra flying points of one Speaker. This means a maximum additional load of 25 kg on each Ancra flying point.

Wrong:

− The suspended speaker weighs more than 50 kg. This exceeds the total load-bearing capacity of the upper flying points.

As a result, a maximum of 2 full-range systems may be suspended under one another.

− The rear suspension point can only support weights up to 30 kg. The flying point is thus not an appropriate secondary device to prevent collapse if another speaker is mounted.

− The angle of the rope/chain in relation to the top of the mounted speaker is less than 45°. This causes the load on the flying points to exceed the permissible level.

Warning

Right:

− A two-point suspension was selected. Each speaker is secured with an additional safety device.

− The suspended speaker weighs no more than 50 kg. This falls within the total load-bearing capacity of the upper flying point.

− The angle of the rope/chain in relation to the top of the mounted speaker is greater than 45°. This maintains a permissible load on the flying points.

4. Coverage Angles of the CA Speakers

The mid-high systems 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 coverage angles of the horn.

4.1 Changing the Coverage Angles

To turn the horn, follow these steps:

1) Remove the four grille mounting screws on the top and bottom of the speaker with a 3 mm socket head wrench and remove the grille from the speaker enclosure.

2) Remove the screws from the high frequency horn (also using a 3 mm socket head wrench). 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 cable, when twisted, may causing the contacts of the driver to become loose.

5. 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.

Important

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", "Ulysses". The Kling & Freitag speaker system data is available for download on our homepage "www.kling-freitag.de".

The following graphics will assist in making a rough estimate as to the distance range of the full-range speakers. 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.

5.1 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.

6. 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 connecting your CA 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 6.2)

− 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.

Important

− 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)

Make sure that the optional XLR type connectors with the exposed male connectors are used as input. This is the only way to provide contact safety from dangerous currents!

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.

6.2 Avoiding Ground Loops

6.2.1 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.

6.2.2 Avoiding Ground Loops

If there is a loud humming or buzzing after the CA 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,

Important

1. the noise is caused by a ground loop before the power amplifiers / controllers (e.g. mixing console, effects or equalizers).

2. the system or parts of the system are connected to an "unclean" power supply

- meaning one, which is also running large motors, or lighting systems. An "unclean" supply voltage, electrostatic and electromagnetic fields can cause a malfunction.

Warning

Important

Please observe the following basic rules:

− Never!!! try to avoid a ground loop by disconnecting or taping the ground contact at the power connector! Extremely dangerous!

− If possible, only use high-quality audio appliances with balanced signal outputs and with power cables with PE connectors.

− Use high-quality cables with good shielding.

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

point. The power connections should lead out in a radial manner from one point and not be linked from one unit to the next.

− When installing appliances that create strong electrostatic or electromagnetic fields (large transformers, switch-mode power supplies), maintain some distance from other audio appliances. In extreme cases, the only solution is to create a completely independent "audio ground"; in other cases, it is sufficient to connect a filter in front of the audio equipment.

7. Configurations and Connecting Diagrams

7.1 Operating the Systems without C2 Controller

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

7.1.1 CA Systems in Full-Range Mode

This mode of operation is ideal for speech applications and music applications without the need for a high bass content. Should more bass be needed, the bass level can be increased between 50 and 80 Hz at the mixing console.

User's Manual CA 1201, CA 1215-6 /-9, CA 1515-6 /-9

7.2 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 functions.

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.

C2- Power amplifier with Controller input level control

Limiter

Measured value (output voltage of the power amplifier)

Universal Power amplifier with Controller input level control

Limiter

Fixed value, depending on the amplifier's gain and the position of the input level control of the power amplifier.

The countersunk switch 'Full-Range Mode' on the C2 Controller should be pressed and the LED assigned to it should light up. The full-range switch accentuates the bass frequencies of the mid-high systems, giving a more balanced sound to music programmes.

When using the mid-high systems in a cluster (speakers in close proximity) or as a stage monitor, activate the "Top Low Cut" switch on the C2 Controller.
