3. Safety�Instructions

3.1 Mounting�the�Speakers�/�Wall�and�Ceiling�Installation

The speakers may only be mounted to wall and ceilings by qualified personnel.

The technicians responsible for assembling the speakers on site are responsible for the safe setup and use of the speakers and guarantee this.

Never use signal cables or power cords for suspending, aligning or securing the systems.

Before carrying through ceiling and wall installations, it is essential to consider the load capacity of walls, ceilings and panelling as well as the stability and type of the construction. If there is wall panelling, for example, it is then necessary to examine the solidity of the wall and use the appropriate wall plugs.

Make sure to comply with the stipulated tightening torques.

If not otherwise stated in this manual, only original KLING & FREITAG parts may be used for mounting the speakers. The use of other parts - in particular parts by other manufacturers - is not permitted in this case.

Ensure that all installation connections comply with the applicable safety guidelines and that the size and strength are sufficient.

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.

As a basic principle, you must visually inspect all components of the speaker before every use. If there are signs of wear, cracks, or deformation, then you must replace the parts immediately. The visual inspection also includes checking the screwed connections on supporting elements.

The information described here does not relieve the user of the duty to follow the given safety requirements and legal regulations.

Caution

3.2 Notes�for�Mounting�the�Speakers

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.

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

3.3 Preventing�hearing�damage

Avoid beeing too close to operating speakers. This equipment is capable of delivering sound pressure levels in excess of 90 dB/SPL, which may cause permanent hearing damage.

Caution

User's manual K&F SCENA 15

3.4 Protecting�the�Speakers�/�Operating�Safety

SCENA 15 speakers may only be used in combination with a K&F SystemRack. See chapter [System Requirements for Use] on page 5.

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 activates a clipping warning signal. In any case, the signal must be reduced as soon as it sounds unnaturally distorted.

For�damage�caused�by

• overloading the speakers

• using the speakers without K&F SystemRack

we do not assume warranty and excludes liability for possible consequential damage.

The�following�signals�may�damage�the�speakers:

• 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 con-nected, 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 connected. 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.

Warning

User's manual K&F SCENA 15

4. Suspending�the�Speakers

With the help of the M8 x 20 eyebolts available as accessories from KLING & FREITAG, the SCENA 15 can be suspended

Screw in at least two of these eyebolts into the existing M8 threads on the sides.

Suspend the speaker with the help of shackles, ropes or chains.

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.

Note that the suspension points on the hall ceiling (i.e. shackles, suspension points, or chain points) must comply with the accident prevention regulation BGV C1 (Event and Production Sites for Stage Presentations) or comparable applicable national standards, and the total load must be approved by an authorised expert.

It is not permissible to suspend anything else from the bottom of the SCENA 15.

User's manual K&F SCENA 15

5. Rotating�the�high�frequency�horn

By default, the SCENA 15 has a coverage angle of 50°x70° (hor. x vert.). When you use it as a stage monitor, you have a good coverage into the depth of the stage and an optimal lateral sound field boundary on the stage. When used on a speaker stand, the practice-orientated directional characteristic of 70°x50° (hor. x vert.) results automatically. For special uses, the horn can also be rotated.

If you wish to rotate the horn, proceed as follows:

1. Remove the grille screws (A) with a 3 mm Allen key and remove the front grille.

2. Remove the horn screws (B) and the chassis screws (D) opposite them with a 4 mm Allen key.

3. Remove the horn.

4. Remove the spacer tubes (C) that are located under the mounting tabs.

5. Place the spacer tubes (C) under the mounting tabs of the new position.

6. Turn the horn by 90° and put it in place while making sure that the socket of the horn is in the

middle of the woofer and securely latches into the groove.

7. Screw on the horn tightly again using the longer horn screws (B).

8. Screw in the shorter chassis screws (D) again.

9. Mount the front grille with the 8 grille screws.

6. Configuration�and�Connecting�Diagram

6.1 1�Channel�Mode

To avoid unnecessarily assigning controller channels, this operating mode is recommended for most usages.

In 1 channel mode, the high frequency driver and the low/mid-range chassis are controlled by one controller channel. The internal crossover takes over the frequency separation for tweeter and low/ mid-range.

In 1 channel mode, a maximum sound pressure of 134 dB SPL is reached.

In general, this sound pressure level is fully sufficient for use as a stage monitor.

User's manual K&F SCENA 15

6.2 2�Channel�Mode

You can use the 2 channel operating mode when you have to slightly increase the maximum sound pressure level.

In 2 channel mode, a maximum sound pressure of 136 dB SPL is reached.

User's manual K&F SCENA 15

6.3 Operations�with�an�Additional�Subwoofer

If you want to operate the SCENA 15 with an additional K&F subwoofer, you must activate the filter button B (100Hz mode) on the CD 44 for the SCENA 15. In doing so, you will get an optimal coupling to the K&F subwoofer systems.

Important

1�Channel�Mode

Activate 'Filter B' for the LSBlock [SCENA 15 1CH].

If necessary, adjust the correct level balance with the output gain of the subwoofer on the CD 44.

2�Channel�Mode

Activate 'Filter B' for the LSBlocks [SCENA 15 2CH LF] and [SCENA 15 2CH HF.].

7. Wiring�instructions

• Before connecting your SCENA 15 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.

Minimum�Wire�Gauge�(mm²) =�Required�Cable�Length�(m)�/�(2�x�Speaker�Impedance�(Ω))

• For connections to the power amplifier inputs, please use 2-pin shielded microphone cable (balanced) with high-quality connectors.

• Avoid ground loops.

• Please pay attention to the pin assignments shown in this 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 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.

• 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(Ω) is not lower than the minimal impedance indicated on the power amplifier.

User's manual K&F SCENA 15

8. Operating�the�Speakers

• Switch off all equipment and turn down all level controls of the mixing console and the power amplifiers.

• Wire your SCENA 15 systems according to the instructions in this 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 to see if the desired signals are applied to the intended speakers and make sure there is no interference. With�controller: The SIGNAL LEDs of the CD 44 Controller will light up if the output level is higher than -45 dB. 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. 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.

Warning

User's manual K&F SCENA 15

9. Transport�and�Storage

The SCENA 15 is protected against short-term moisture. It should still be stored, transported, and used under dry conditions, though. The SCENA 15 System is not designed for long-term use in a corrosive environment.

Make sure that the system is adequately ventilated during longer storage periods so that possible residual moisture can escape from the equipment.

Furthermore, you should ensure that the SCENA 15 System is protected from mechanical strain to prevent possible damage.

We recommend using suitable transport and storage cases and the optional soft cover that protects from the above-mentioned influences.

10. Maintenance�and�Care

For the owner and user, it is mandatory to be aware of the safety relevance of speakers that can be flown.

It is, therefore, highly essential to carry through meticulous and well-documented maintenance procedures and inspections.

The SCENA 15 system can exhibit signs of wear over the years, i.e. from mechanical strain, transport damage, corrosion, or improper handling. If speakers are to be flown, this always means there is a high safety hazard.

As a basic principle, you must visually inspect the SCENA 15 System every time you suspend it and take it down. For fixed installations, you must inspect the speaker for signs of wear at regular intervals.

During these inspections, you must especially look out for deformations, cracks, dents, damage to threads, and corrosion. Mounting devices such as shackles, chains and wire ropes also have to be checked for signs of wear or deformation carefully.

If as a result of these checks any uncertainty should arise with regard to safety or if specific faults are found, the SCENA 15 system may no longer be used and you must send in the product to KLING & FREITAG GmbH for inspection and repairs, if necessary. If defects are ascertained, then you must send in the product to KLING & FREITAG GmbH for inspection and repairs, if necessary.

The�inspection�requirements�vary�depending�on�application�and�country�of�use.�Observe the�requirements�that�are�relevant�for�you.�If�in�doubt,�contact�local�authorities.

In many countries, regular inspection of mounting components and accessories is required. In most cases (e.g. german BGV C1), an additional annual inspection is required that must be done by a technical expert. Additionally, a detailed inspection carried through by a legally certified or official authority is required every four years.

In this context, it is very important to keep an inspection log book. In this inspection log book, the data for every used accessory is entered at the periodic inspections, making the data available at all times for possible inspections. This book should document maintenance measures and inspection intervals and contain parts lists.

2. Twice a year, turn on the switch in the speaker’s connector area so that it stays functional.

3. The Polyurea synthetic coating used by KLING & FREITAG is impact proof and highly resistant. We

recommend using protective coverings or cases to help avoid damaging the paint during i.e. continuous mobile use

4. To replace the filter foam, send the front grille incl. foam to KLING & FREITAG GmbH. Upon pay-

ment for expenses, the grille with the new covering will be returned.
