3. Safety Instructions

Warning

For commercial use as specified in this document only! To prevent personal injury and damage, be sure to securely place or suspend the speaker as

specified in the locally applicable standards. The information described here does not relieve the user of the duty to follow the given

safety requirements and legal regulations. Only qualified technicians are permitted to perform the installation steps. Be sure to use

personal protective equipment at all times. The persons in charge with putting up the speaker are responsible for safe setup and use and

must guarantee it. In mobile and stationary installations, always use installation parts supplied by KLING &

FREITAG. Unless otherwise stated, use KLING & FREITAG original parts only. Never use other parts (in

particular, parts not made by KLING & FREITAG). Be sure to always visually inspect all safety-related speaker and accessory components before

use. In fixed installations, check the speaker for signs of wear at regular intervals. If there are signs of wear, cracks, or deformation, etc., replace the affected parts immediately.

Caution

Run the cables in a way that nobody can trip over them. At least 2 people are necessary to carry the speaker.

Preventing Hearing Damage

Keep your distance from operating speakers. Even loudness levels of approx. 90 dB - that you subjectively judge as being low - can lead to hearing damage.

3.1 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.

3.2 Instructions for Speaker Stacking

Warning

Falling speakers pose the threat of fatal injuries to people near them!

Be sure to follow the relevant national specifications, norms, and safety regulations. Always make sure that a sufficient safety level is still given, even when outside forces have

an additional impact on the stacked speakers. Before setup, carefully ascertain if there are any possible outside forces that could result in the array falling over. (Slant of the ground / the bearing capacity of the ground / wind / person or vehicle impact, etc.). A technical expert who is responsible for the setup must evaluate and determine necessary measures (including calculating the statics). If necessary, obtain expert proof of stability.

Stacked systems may not fall over even if they are inclined by 15° 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. A planned tilt of the loudspeakers ist not permissible. In calculations, the tilted setup serves the purpose of levelling out unevenness.

Page 7

User's Manual K&F NOMOS XLT

With the set-up systems for which you cannot verify the structural safety without safeguards, you must secure them to prevent sliding or tipping in order to provide proof of this safety. To secure the system from tipping over, use water tanks or floor bolts. Other possible measures include strapping it to a suitable substructure or tying it using safety straps.

For outdoor and trade fair venues in which wind loads must be considered, additional proof of stability is necessary.

Make sure that the stacking feet of subwoofers stacked on top of one another are securely positioned in the grooves of the lower speaker.

If you place a top speaker on a NOMOS XLT you must always strap the speakers to one another and secure them from falling over.

3.3 Protecting the Speakers / Operating Safety

NOMOS XLT speakers may only be used in combination with a K&F SystemAmp/SystemRack. 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 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 or

• using the speakers without K&F SystemAmp/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 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 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.

4. Setup

4.1 Removing the Transport Covers

To remove the transport lid, turn the appropriate catches 180° to completely release the latch.

Lift the lid from the speaker.

4.2 Stacked Setup

1) Securely place the bottom subwoofer onto a level surface.

2) Stack the subwoofers on top of one another. Make sure that the stacking feet of subwoofers stacked on top of one another are securely positioned in the grooves of the lower speaker.

3) Stacked systems must be stable even if they are inclined by 15 degrees without additional additional securing.

If this is not the case the systems have to be secured against falling over in order to guarantee the stability of the stack.

User's Manual K&F NOMOS XLT

5.4 Cardioid Arrays with NOMOS XLT

The subwoofer NOMOS XLT is designed so that it can be used as a cardioid and hypercardioid system in an array of three subwoofers, or in multiples of three.

A cardioid array results in an increase of sound pressure towards the front because of the rear-facing subwoofer. In the rear area (cardioid) or in the lateral side area (hypercardioid), on the other hand, the sound pressure is clearly reduced.

With this, you achieve

• less unwanted sound on the stage

• low feedback

• simplified miking

• improved room acoustics with fewer reflections from the rear and side walls, or – when flown – from the ceiling

• simplified adherence of sound emission limits and therefore less noise disturbance for nearby residential areas during open air events.

5.4.1 Setup instructions for a cardioid array

To achieve a cardioid or hypercardioid pattern, you must always have an array with 3 subwoofers - or a multiple of 3 subwoofers - setup next to one another (3, 6, 9, etc.). In this set of three, the middle one must be stacked or flown rear-facing while both other subwoofers are front-facing.

You can stack the subwoofers even when they are facing opposite directions, and you can connect them to front-facing systems.

There is an additional SpeakOn connector on the front grille so that you can connect the cables to the rear-facing side of all subwoofers in a cardioid array.

You can choose from the following options for cardioid and hypercardioid setups: Unifilar drawing:

3 x NOMOS XLT horizontal

3 x NOMOS XLT vertical

3 x NOMOS XLT stacked

Page 13

User's Manual K&F NOMOS XLT

When cardioid arrays are stacked on the floor, ensure that there is always a distance of at least 40 cm between each unit of 3.

40 cm (1.3 ft)

5.4.2 LSBlocks for cardioid use

The rear-facing subwoofer is controlled using the Controller CD 44 via LSBlock for cardioid / hypercardioid arrays for rear-emitting subwoofers. The front-facing subwoofers are controlled via LSBlock for cardioid / hypercardioid arrays for front-emitting subwoofers. The following cardioid or hypercardioid setups are available in the CD 44:

User's Manual K&F NOMOS XLT

5.5 Cardioid Configurations with different Speakers

NOMOS XLT are suitable for cardioid configurations with certain K&F speakers. A chassis ratio of 1 to 2 should be maintained within these configurations.

The speaker with one chassis should be standing on the floor and directed to the rear while the speaker with two chassis directs to the front.

6. Fuse in the NOMOS XLT

To increase the operating safety of the NOMOS XLT, the subwoofers are equipped with fuses at the signal input. These fuses reduce the risk of consequential damage resulting from a short circuit (i.e. charred cables / connectors / fire damage).

When the fuse is burned out, then the chassis is most likely already ruined, as the fuse just prevents consequential damage resulting from a short circuit of the chassis. A replacement of the chassis is, therefore, unavoidable.

6.1 Replacing the Fuses

The fuse holder is behind the terminal.

Warning

Replace the fuse with the following original fuse only:

Bussmann S 506-8A, T 250 V

Required tools:

• 2.5 mm Allen key for loosening the terminals

Instructions:

1. Loosen the four screws on the terminal.

2. Carefully pull the cables out of the speaker enclosure.

3. Open the fuse holder.

4. Replace the blown fuse.

5. Push the cables carefully back into the enclosure.

6. Pay attention to the correct alignment of the terminal.

Screw the terminal back on.

6.2 Replacing the Chassis

Required tools:

12. Care and Maintenance

Warning

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

The NOMOS XLT system can exhibit signs of wear over the years, for example, from mechanical strain, transport damage, corrosion, or improper handling. Remember that flying speakers always impose a high safety risk.

Generally, perform a visual inspection of your speaker every time you suspend it or take it down. In fixed installations, check the speaker for signs of wear at regular intervals.

When performing those checks, particularly look for deformations, cracks, dents, damage to threads, and corrosion. Also check slings and lifts (e.g. shackles, chains, and steel ropes) carefully for wear and deformation.

If as a result of these checks any uncertainty should arise with regard to safety or defects are found, don’t use the speaker any longer.

Inspection regulations may vary depending on application and country of use. Observe all applicable regulations; when in doubt, contact the local authorities.

Many countries require regular inspection of mounting components and accessories. An additional annual inspection is typically required to be performed by a technical expert. Moreover, a legally certified or official authority must perform a detailed inspection every four years.

Therefore, be sure to maintain an inspection log. Enter the values determined for each speaker and accessory during the periodic checks into this log. This way, relevant data are always at hand in case of inspection. The log should also document maintenance measures and inspection intervals and contain parts lists.

The Polyurea synthetic coating used by KLING & FREITAG is impact proof and highly resistant. We recommend using protective coverings or transport cases to help avoid damaging the paint in case of continuous mobile use, etc.

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.

13. Transportation and Storage

The NOMOS XLT is protected against short-term moisture. despite, be sure to store, transport, and use the accessories in dry environments only. The NOMOS XLT 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 any residual moisture can escape from the equipment.

Furthermore, you should ensure that the NOMOS XLT 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.

14. Disposal
