General Safety Instructions for Speakers

Mounting the speakers

Warning

To prevent injury, this equipment must be securely placed on the floor or secured to the wall according to the mounting instructions on page 16 (Mounting Instructions for Speakers). 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. If the weight of the speaker exceeds 20 kg then it is necessary for two people to carry it.
Speakers may only be mounted to wall and ceilings by qualified personnel. The speakers must be hung by using at least two of the designated flying points. The same applies when lifting and aligning the speakers.
Never use signal cables or power cords for suspending, aligning or securing the systems. When laying the connecting cables, make sure that nobody can trip.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG.
Ensure that all installation connections comply with the applicable safety guidelines 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 included safety and mounting Instructions for loudspeakers and accessories.
Speakers and rigging equipment must be visually examined at regular intervals. If there are signs of wear, they must be replaced immediately. Furthermore, screwed connections of supporting parts must be checked routinely.

Protecting the speakers / operating safety

Important

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, they should only be operated with professional power amplifiers with a maximum rated power of 1400W@6Ω
  (equivalent 2100W@4Ω).

• If power amplifiers have power ratings lower than mentioned above, then it is imperative that a clipping limiter is used to protect the speaker even if it is used with a Kling & Freitag system controller.

• Operating safety and maximum performance of the LINE 212 System can only be guaranteed when used with a K&F System Controller. We cannot offer a guarantee for overload damage resulting from use with a controller aside from a K&F System Controller.

For damage caused by

• overloading the speakers
• using the speakers with power amplifiers other than those recommended above
• using the speakers without a controller or with a controller other than a K&F System Controller,

Kling & Freitag GmbH does not assume warranty and excludes liability for possible con-sequential damage.

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.

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.

Important Notes for the ‘Outdoor’ Option

Warning
Speakers with the option ‘Outdoor Mobile’ and ‘Outdoor Installation’ have been optimised for outdoor use. They withstand temperature fluctuations in moderate climate zones and do not accumulate condensation water.
In order to guarantee the longevity and safety of the speakers, the speakers with the option ‘Outdoor’ must still be protected from direct effects of the weather.
They should be installed, for example, under a roof so that they also have sufficient protection from driving rain from the side and direct sunlight.

‘Outdoor Mobile’

Version for mobile outdoor use under roofs.
Features like standard version but with the following extras:

• multi-layered, temperature and UV-resistant high-tech PU marine primer,
• final coating with highly resistant structured 2K paint in RAL colours,
• waterproofed diaphragms and electronic components protected against corrosion with protective coating.

‘Outdoor Installation’

Version for fixed outdoor installations under roofs.
Features like ‘Outdoor Mobile’, but with the following differences:

• No handles, feet, stacking foot grooves and locking profile for transport cov-er.
• Stainless steel flying points M 10 x 18 instead of ‘allsafe JUNGFALK’ flying points (positions and load capacity are the same)
• Instead of rear mounted flying tracks: two stainless steel thread inserts M 10 x 18 as flying points (load capacity 60 kg / point)

Tighten all screwed connections on the speaker and protect them against coming loose.

• Single stainless steel grille instead of parted steel grille.
  a. The complete grille must be removed when turning the horn. Remove the screws on the grille.

Rigging Instructions for Line 212 Systems

The speakers may only be mounted by trained specialised personnel with proof of their qualifications as a certified ‘rigger’.
Please follow the accompanying instructions for speakers and assembly equipment.
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.
Warning
Pay attention to the required safety factors. Make sure to observe the included safety and mounting instructions.
A maximum load of 73 kg may be suspended from the two flying points of one Line 212 system. This means a maximum additional load of 36.5 kg on each ‘allsafe JUNGFALK’ flying point. This applies for both vertical (see details on this page) and horizontal suspension (see details on next page).

Vertical Suspension

The Line 212 System must always be mounted with two wire ropes or chains, which are independent of one another! Furthermore, the systems, no matter if individual or connected to one another, must be secured onto the ‘allsafe JUNGFALK’ flying track on the rear. This safety rope may be used for aligning the systems.
The safety rope must have a minimum length of 100 cm and must be attached so that, in case it falls, the height of the fall is kept to a mini-mum. A possible fall height of 20 cm may not be exceeded! With a higher fall height, the dynamic load of a fall could be inadmissibly high; potential risk of system crash. The safety ropes of different systems must always come together at one point.
Each of the utilised separate lifting accessories (chains / wires / shackles) must be able to carry the 12-fold load of the total weight.
While installing, be sure that the system can swing in case a rigging point fails. With this in mind, the speaker must be mounted so that no people or objects are within the potential range of the swing-ing speakers. The weight of the speaker hung below may not exceed 73 kg (this weight corresponds to the approx. weight of a SW 215E-SP).
The angle of the rope / chain to the top of the speaker mounted below may not exceed 45°.

Horizontal Suspension

If a speaker unit consisting of several connected systems is to be flown and aligned, then the individual speakers must be attached to one another before connecting them to the ‘allsafe JUNGFALK’ Flying Track. Consult the provided illustration when doing so. For the rear connection of the loudspeaker systems use the double stud fittings available from Kling & Freitag and a proven 1/2″ shackle (alternative single stud fittings and 3/8″ shackle). Pull the threaded bolt of the shackle with a torque of 10 Nm (hand-tight with 200 mm long lever, e.g. screwdriver). Alternatively, you can use proven, high-strength shackles with a split pin. Only in this way can you ensure that the bolt will not become loose.

The ‘allsafe JUNGFALK’ Flying Track can only support weights up to 73 kg. Therefore the load must be distributed on several flying tracks when suspending the systems.
For horizontal operations, the system is designed for a maximum array of 3 Line 212-6 systems. More of theses systems may not be flown below one another.
We recommend using the BGV C1 certified and type tested Click & Fly Rigging System for mounting the Line 212 systems (see the ‘Click & Fly for Line 212 / SW215E’ user’s manual).
Please pay attention to the following instructions for flown operations without the Click & Fly rigging system:

Wrong:

• The upper rigging points of the top speaker must carry the full load. Consequently, the permissible max. load of the top points is exceeded.
• The speakers are not secured by the additional safeties

Right:

• The load of the individual speakers is threaded through the bent continuous bracket. The load is, therefore, held by the bracket, and the speakers’ flying points consequently only have to carry the load of the corresponding speaker.
• The speakers are connected to one another on the rear. The suspension point is located on the connection of the two lower speakers. As a re-sult, the load is distributed to both speakers.

Coverage Pattern of the Line 212 Systems

The Line 212 can be operated in a vertical or horizontal position. The coverage pattern of the speaker can be adapted to special needs by a 90° rotatable horn.
The following graphics demonstrate how to recognize how the built-in horn emits in 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.

DEFINITION:

Changing the Coverage Pattern

The front grille of the Line 212 is divided into two sections (except the version ‘Outdoor Installation’). Changing the coverage angle is possible by only removing the upper sec-tion of the grille. To turn the horn, follow these steps:

1. Remove the four grille mounting screws from the top on the sides of the speakers with a 3 mm Allen key and remove the grille from the speaker enclosure. It may be necessary to use a screwdriver in the middle of the top grille edge to pry up the grille. There is a groove in the grille in this position (under the locking profile) just for this purpose.
2. Remove the 6 screws from the high frequency horn (also using a 3 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 be-hind 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.
5. You will notice twelve fastening screws under the front foam of the ‘Outdoor Installation’ version. Lift up the front foam carefully and loosen the screws with a screwdriver for cross-recessed screws. Remove the grille from the speaker enclosure. Continue with step 2).

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 may cause the contacts of the driver to become loose.

Mounting Instructions for Speakers

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 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 struc- ture or fastening it using safety straps.

We recommend using the optionally available transport covers with castors when trans- porting and positioning the system. These covers have handles, which considerably simplify the carrying and stacking of the Line 212 Systems. We therefore recommend
removing the covers after the systems have been positioned. Always loosen the lower catch first so that the cover does not fall over.

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 possi-ble 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 pro-grams 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 speaker systems. 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 notice-able deviation.

Distance range of SPL (direct sound level):

Arrayed Speaker Systems (Cluster)

If the loudspeakers are operated through an optional K&F System Controller, we rec-ommend to turn on the ‘Top Low Cut’ filter for clustered operation. Thus the frequency response for this application can be optimised (see user’s manual of the controller).
If the Line 212 Systems are operated in a cluster without a K&F System Controller (speakers are set up directly next to one another), then lower the ‘EQ LOW CUT’ fre-quency as described below!

EQ LOW CUT

• Frequency: 120Hz
• Quality (Q): 0.55
• Bandwidth (oct.): 2.35
• Level: -2.95dB

1. If several Line 212-6 with a horn coverage pattern of 65°h x 50°v are arranged on one side (cluster / array), it is recommended for the Line 212-6 to have a horizontal array angle of 38.5° to one another (see fig. 2).
2. In a cluster comprised of a combination of the Line 212-6 with Line 212-9, we recommend an array angle of 45° (see fig. 3).
3. With a rotated horn (Line 212-6 standing: 50°h x 65°v / Line 212-9 standing: 50°h x 90°v), an array angle of 30° is recommended for both versions (see fig. 1).

Because increased interference effects occur when several 90° systems are arranged next to one another, the clustering of several Line 212-9 is only conditionally recom-mendable.

LINE 212 Systems on Top of SW 215E

In addition to the stacking foot grooves for stacks of identical enclosures, the subwoofer SW 215E also has stacking foot grooves for the Line 212 System.
One Line 212 System can be quickly and safely posi-tioned on top of a vertically placed SW 215E.
Two Line 212 Systems can be precisely arrayed on top of a horizontally placed SW 215E.
Mounting Instructions for Speakers

Other combinations of Line 212 Systems are not recommended as they can cause un-wanted interferences

Operations with K&F System Controller

For optimal performance and operating safety we recommend using a K&F system controller. Instructions for use, connecting diagrams and detailed descriptions of the latest controller models ‘CD 24’ and ‘CD 44’ you can find in the corresponding user’s manuals.
Important
We do not recommend operations without a K&F System Controller.
Operating safety and maximum performance of the LINE 212 System can only be guar-anteed when used with a K&F System Controller. We cannot offer a guarantee for over-load damage resulting from use with a controller aside from a K&F System Controller. As a rule, the Line 212 systems should only be operated with a system equalisation (filter). If, despite this risk, the LINE 212 system should be run with a controller aside from the K&F CD 24, CD 44 or C2, we will send further instructions upon request.

Wiring

The Speaker is equipped with two parallel-wired Speakon connectors.
Before connecting your Line 212 system, be sure to switch off all connected appliances and turn down all level controls.

• We recommend the use of high-quality 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.
• Please pay attention to the respective pin diagrams in this manual!
• To ensure an in-phase operation and, consequently, a homogeneous sound, 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 con-figuration on the power amplifiers or on the connectors leading to them.
• 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’s Impedance (Ω)

If several loudspeakers are connected, the signal can be linked through from one loud-speaker to the next. Please make sure that the total impedance of the loudspeakers R (W) is not lower than the minimal impedance indicated on the power amplifier.
1/R1 + 1/R2 + 1/R3 + … = 1/Rtotal

Connecting the Speakon Plugs to the Connecting Terminal

10.2 Avoiding Ground Loops

What is a Ground Loop?

Every component of a P.A. or Hi-Fi System has its own internal 0V 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.

Avoiding Ground Loops

If there is a loud humming or buzzing after the speaker has been connected, then check that a “ground loop” has not been built into the system. Some power amplifiers and system controllers facilitate a ground lift switch. Set these ground lift switches to the ‘Lift’ position one after the other. If the noise is still audible, check if

1. the noise is caused by a ground loop before the power amplifiers or 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 ‘un-clean’ supply voltage, electrostatic and electromagnetic fields can cause inter-ference.

Please observe the following basic rules:

• Never!!! try to avoid a ground loop by disconnecting or taping the protec-tive earth contact at the mains connector! Extremely dangerous!
• If possible, only use high-quality audio appliances with balanced signal outputs and power cords 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 independ-ent ‘audio ground’; in other cases, it is sufficient to connect a filter in front of the audio equipment.

Operating the LINE 212 System

• Switch off all equipment and turn down all level controls.
• Wire your LINE 212 System.
• 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.
• Now switch on the peripheral equipment first (mixing console, effects etc.), followed by the K&F system controller, if used, and the power amplifiers. Always use the before mentioned switching order. Otherwise switching noises may damage the systems.
• 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 to see if the desired signals are applied to the in-tended speakers and make sure there is no interference. Make sure everything works properly, i.e. if the signals come from the correct speaker paths (high signals from the tweeters, bass signals from the bass speaker). 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 from protection circuits or damages to the speak-ers, turn the level controls of the power amplifier to the maximum position, if pos-sible. 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.
• Please pay attention to the instructions in the user’s manual of the controller and to the supplied safety instructions for loudspeakers and mounting accessories.

Fuses and Protection Circuits

The LINE 212 is equipped with protection circuits, which cut off the signal current when highly overloaded – for the 1.5″ high frequency speaker as well as for the crossover. If the high frequency speaker of the Line 212 turns off, reduce the volume. After a few seconds, it will turn back on automatically.
If there is operating trouble, the low-mid crossover circuits are protected with fuses. Blown fuses can only be replaced with fuses with the following specifications:
250V T4L (DIN EN 60127-2-3)
Do not use fuses with different specifications and do not try to bypass the fuse as this may cause fire hazard.

Touching Up Damage to Paint / Changing the Front Foam

Although the PU structured paint used by KLING & FREITAG is extremely resistant, we recommend using protective covers 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.

Regulations for Disposal

Germany

It is not allowed to dispose of used electrical equipment as domestic waste.
But please do not dispose of them at official collecting points for recycling either!
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 dis-posed 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 GmbH 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.

EU, Norway, Iceland, and Liechtenstein

It is not allowed to dispose of used electrical equipment as domestic waste.
The Kling & Freitag GmbH 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 pro-hibited 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.

Other Countries

For proper disposition of used products in accordance with local provisions in other countries please ask your local dealer or the local authorities.
