Safety Instructions

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 of 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 genuine KLING & FREITAG 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 stationary installations, check the speaker and accessories for signs of wear at regular intervals. If there are signs of wear, cracks, or deformation, etc., replace the affected parts immediately. VORSICHT When laying the connecting cables, make sure that nobody can trip. 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 judged as being low – can lead to hearing damage.

Instructions for Speaker Placement

Instructions for Speaker Stacking
WARNUNG Mount the speakers securely. To avoid injury or damage, always be sure to mount the speakers securely so that they do not fall. Note that the speakers can move as a result of vibrations. To prevent them from falling from
their mounted position, they must be secured properly. When laying the connecting cables, make sure that nobody can trip.
WARNUNG Tipping speakers impose a deadly risk for people standing nearby! Be sure to follow the relevant national specifications, norms, and safety regulations. Always make sure that the speakers are sufficiently secured, so they cannot fall over even when external forces affect the speaker stack. Before installation, carefully check whether there are any external factors that may cause the stack to fall over. These include, for example, the ground slope or bearing capacity, winds, and impacts of persons or vehicles. Qualified and appropriately trained installation personnel are in charge of evaluating the scenario and performing all required steps (including statics analysis). Proof of stability must be obtained if and as necessary.

Stacked systems must not fall over even if they are inclined by 15° in any direction. If this requirement is not fulfilled, be sure to take appropriate steps. E.g. lashing the? speakers onto a suitable base or fasten them using straps. Never allow the intended speaker to tilt. The corresponding feature is simply used to account for unevenness during stability evaluation. Where the stability of installed systems cannot be proven without additional safety measures, those systems must be effectively secured against sliding and tipping to achieve compliance. For example, secure the system against tipping using water tanks or floor bolts. Other possible measures include lashing the speakers onto a suitable base or fastening them using straps. With applications where winds may occur, for example, outdoor events, tradeshows, etc., be sure to perform extra stability checks. Make sure that the feet of stacked subwoofers engage with the corresponding hollows 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.

Protecting the Speakers, Reliability
HINWEIS Be sure to connect the K&F NOMOS XLT speaker to a K&F SystemAmp, a K&F SystemRack, or a linear power amp with up to 750 Wrms per channel (8 ohms) only. Never feed audio at excessive levels to the speaker. This may be caused by mixing consoles, equalizers, effect equipment, etc., and should be indicated on this equipment. Clipping at the power-amp output is typically shown by a red clipping indicator. In any case, be sure to lower
the signal level once it sounds distorted. For damage caused by

• Overloading the speakers or using the speakers without K&F SystemAmp or K&F SystemRack
• We do not assume warranty and exclude liability for possible consequential damage.
• Signals that may damage the speakers include the following:
• Continuous high-volume signals at high frequencies, continuous audio feedback
• Continuously distorted signals at high levels
• Sounds occur when connecting, disconnecting, or switching on a device on the audio system while the speaker is on

Never place your speakers

• where they are permanently exposed to direct sunlight,
• or where the devices are exposed to high moisture or rain.
• where they are exposed to strong vibrations or dust.
• Damage Caused by the Speaker’s Magnetic Fields
• Even when not connected, loudspeakers continuously produce a magnetic field. Therefore,
• When transporting or placing the speaker, be sure to keep a minimum distance of about a meter between the speaker and magnetic disks or computer/video displays.

Installation

Removing the Transport Covers
To remove the transport lid, turn the appropriate catches 180°. This turn completely releases the latch. Lift the lid from the speaker.

Stacked Setup
Securely place the bottom subwoofer onto a level surface. Stack the subwoofers on top of one another. Make sure that the feet of stacked subwoofers engage with the corresponding hollows of the lower speaker 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

Suspending the Speakers
On the following pages, you can find out about the differences between the options
WARNUNG The information described here does not relieve the user of the duty to follow the given safety requirements and legal regulations. The technicians responsible for installing the system on-site are responsible for and guarantee safe setup and use.

Option ‘Flight’
When laying the connecting cables, make sure that nobody can trip. Unless otherwise stated, use only KLING & FREITAG original parts for mounting the speakers. Never use other parts (in particular, parts not made by KLING & FREITAG). Be sure to always visually inspect all components before use. In fixed installations, regularly check all system components for signs of wear. To prevent injury and damage, be sure to securely place or suspend the speaker as specified in the DGUV regulation 17 (BGV C1) or similar locally applicable accident-control standards. Also check slings and lifts (e.g. shackles, chains, and steel ropes) carefully for wear and deformation. If there are signs of wear, cracks, or deformation, etc., replace the affected parts immediately. See also the »Care and Maintenance« Chapter on Page 30

Safety Instructions for Flying Configurations
WARNUNG Loudspeakers falling down impose a deadly risk for people standing nearby! Never use the system if you have any doubt regarding its safety and reliability! Only qualified event technicians are permitted to suspend a NOMOS XLT system. Maximum-load specifications refer to configurations including cabling and any fittings. 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. Follow the relevant specified safety factors. Be sure to follow the relevant national specifications, norms, and safety regulations.

Note that every suspension point as well as the supporting structure of the building (i.e. ceiling points, cross beams stage or PA tower, etc.) must be capable of carrying the total load of the system (including cabling and additional fittings). Beachten Sie, dass die Befestigungspunkte an der Hallendecke (z. B. Lastösen, Anschlagpunkte oder Kettenzüge) der Unfallverhütungsvorschrift DGUV Vorschrift 17 (BGV C1) oder den entsprechenden Sicherheitsvorschriften Ihres Landes entsprechen und die Gesamtlast von einem ermächtigten Gutachter abgenommen wurde. When in doubt, request a confirmation by local authorities.

Even with two-fall suspension, each chain and motor must be capable of carrying the entire loudspeaker mass! Make sure that the motor chains hang down vertically and are not twisted, and that the motors are located at the required positions. When operating with chain hoists that do not comply with the BGV C1 or the D8+, no one may be present in the danger zone underneath or near the loudspeakers. 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. Permit only personnel directly involved with assembly or disassembly to access the working area. In this case, all persons present must leave the swing and lifting range immediately

Wind loads

wind.
3| 3.4–5.4| Gentle breeze| Leaves and small twigs in constant mo- tion; light flags ex- tended.
4| 5.5–7.9| Moderate breeze| Raises dust and loose paper; small branches moved.
5| 8.0–10.7| Fresh breeze| Small trees in leaf be- gin to sway; crested wavelets form on in- land waters.
6| 10.8–13.8| Strong breeze| Large branches in mo- tion; whistling heard in telegraph wires.
7| 13.9–17.1| High wind| Whole trees in mo- tion; inconvenience felt when walking against the wind.
8| 17.2–20.7| Gale| Twigs break off trees.

In case of outdoor use, stay informed of the latest wind and weather conditions. See the following table for provisional guidance. For outdoor uses, we recommend using at least a BGV D8+ hoisting device to prevent secondary safety devices from loosening in the wind. When wind speeds exceed 5 ft, be sure to constantly monitor the wind speeds and consider possible wind effects on flying speakers. Also, remember that wind speeds increase with height. If wind speeds exceed 5 ft, be sure to choose rigging and securing so that they are able to absorb at least twice the static load. With wind speeds equaling or exceeding 6 bit, be sure to immediately clear the area below the speakers. Use roping or lateral spanning to effectively prevent motion build- up of flying speakers. Failing to do so may result in the emergence of large inertial forces leading to the tower collapsing or tipping over. At wind speeds equaling or exceeding 8 bit, be sure to get down and uninstall flying speakers

NOMOS XLT Option ‘Flight’
NOMOS loudspeakers with flying points are special models and must be ordered with the option ‘Flight’.
WARNUNG Only NOMOS XLT speakers with flying points may be suspended. LSblocks*
Option 1: They are suitable for K&F ball lock pins ‘Lifting Pin’ and screw inserts with M10 x 17 thread, e. g. a permissible ring bolt (DIN 580). NOMOS XLT Loudspeakers must be suspended from at least two flying points. If you wish to install a safety lane at the third flying point, the safety lane must be installed without a drop path.

Possible options for flying point positions
The NOMOS XLT subwoofer can be ordered in four different flight versions: Safety instructions for flight configurations

NOMOS XLT combined with other K &F tops
The NOMOS XLT can only be combined in 2-channel mode with all K&F top speakers when using a K&F system amp or system. To do so, select the desired LS blocks for the top speaker in the K&F system amp or system rack, and combine these with the LS block for the NOMOS XLT subwoofer you need a higher bass level, activate the filter ‘BassBoost’ via Filter B for the subwoofers. If you need a higher level at the overlap range between subwoofer and top activate the filter ‘LoMidBoost’ via Filter B.

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 to sound emission limits and therefore less noise disturbance for nearby residential areas during open-air events.

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 – set up 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 frontfacing. 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:

Principle drawing:3 x NOMOS XLT horizontal
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. Principle drawing

LSBlocks for cardioid use
The following cardioid or hypercardioid setups are available in the system rack/system amp: Operation Mode of the NOMOS XLT LSblocks (names can differ slightly)

• ‘Cardioid Front’, front-facing NOMXLT C-F
• ‘Cardioid Rear’, rear-facing NOMXLT C-R
• ‘Hypercardioid-Front’, front-facing NOMXLT HC-F
• ‘Hypercardioid-Rear’, rear-facing NOMXLT HC-R
• ‘Infrabass Cardioid Front’, front-facing NOMXLT C-F60Hz
• ‘Infrabass Cardioid Rear’, rear-facing NOMXLT C-R60Hz
• ‘Infrabass Hypercardioid Front’, front-facing NOMXLT HC-F60Hz
• ‘Infrabass Hypercardioid Rear’, rear-facing NOMXLT HC-R60Hz

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

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

1 x NOMOS XLS under NOMOS XLT?
When the fuse is burned out, 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

Replacing the Fuses

• The fuse holder is behind the terminal.
• 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.
7. Screw the terminal back on.

Replacing the Chassis
Required tools:

•  3 mm Allen key for loosening the front grille
• 4 mm Allen key for loosening the chassis

Instructions

1. Remove the front grille.
2. Remove the speaker chassis.
3. Pay attention to the correct polarity of the chassis.
4. Connect the new chassis.
5. heck, the polarity of all mounted chassis.
6. By tightening the screws diagonally in two steps, a deformation of the chassis and thus a possible decentering of the voice coil can be avoided. First, loosely screw the chassis crosswise. Then tighten it crosswise.
7. Mount the front grille.

Care and Maintenance

For the owner and user, it is mandatory to be aware of the safety relevance of speakers that can be flown. The K&F 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. Be sure to always perform a visual inspection of the speaker and all accessories before and after installation. In stationary installations, check the speaker and accessories 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; If in doubt, contact 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. This inspection logbook shall be updated with the inspection steps, test intervals, and parts lists. The polyurea coating utilized by KLING & FREITAG is shock-resistant and highly resilient. We recommend using protective coverings or transport cases to help avoid damaging the paint in case of continuous mobile use, etc. To have
the acoustic foam replaced, send the grille including the foam layer to KLING & FREITAG GMBH.

Transportation and Storage
The K&F NOMOS XLT system is protected against the effects of unfavorable temporary weather conditions, etc.;, be sure to store, transport, and use the accessories in dry environments only. The K&F NOMOS XLT is not designed for prolonged use in corrosive environments. Make sure that the system is adequately ventilated during longer storage periods so any residual Moisture can escape from the equipment. In order to prevent damage, please make sure to avoid mechanical strains. To protect the speaker from the above impacts, we recommend using the optional soft cover and suitable transport and storage cases
