WARNUNG
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 per-
sonal 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 & FREIT-
AG.
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 im-
mediately.
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 judge as being low - can lead to hearing damage.

3.1 Instructions for Speaker Placement
3.2 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 near-by!
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 ap-
propriately trained installation personnel are in charge of evaluating the scenario and perform-
ing 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 re-
quirement is not fulfilled, be sure to take appropriate steps. E.g. lashing the
speakers onto a suitable base or fastening them using straps. Never allow intended speaker
tilting. 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.

User's Manual K&F NOMOS XLT
3.3 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 excludes 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 occurring 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,
•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
1 meter between the speaker and magnetic disks or computer/video displays.

4 Installation
4.1 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.
4.2 Stacked Setup
1. Securely place the bottom sub-
woofer onto a level surface.
2. Stack the subwoofers on top of
one another. Make sure that the
feet of stacked subwoofers en-
gage with the corresponding
hollows of the lower speaker.
WARNUNG
3. Stacked systems must be stable
even if they are inclined by 15
degrees without additional addi-
tional securing.
If this is not the case the systems
have to be secured against fall-
ing over in order to guarantee
the stability of the stack.

5 Suspending the Speakers
5.1 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 se-
curely 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 defor-
mation, etc., replace the affected parts immediately. See also the »Care and Maintenance«

5.1.1 Safety Instructions for Flying Configurations
WARNUNG
Loudspeakers falling down impose a deadly risk for people standing near-by!
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, stati-
cally 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 specifica-
tions, norms, and safety regulations.
Note that every suspension point as well as the supporting structure of the building (i.e. ceiling
points, cross beams and 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 ent-
sprechenden 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 ar-
ea. In this case, all persons present must leave the swing and lifting range immediately.

0 0–0.2 Calm Smoke rises vertically.
1 0.3–1.5 Light air Direction shown by
smoke drift but not by
wind vanes.
2 1.6–3.3 Light breeze Wind felt on face;
leaves rustle; wind
vane moved by 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

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.
WARNUNG
For outdoor uses, we recommend using at least a BGV D8+ hoisting device to prevent the sec-
ondary safety device from loosening in the wind.
When wind speeds exceed 5 bft, 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 might exceed 5 bft, 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 bft, be sure to immediately clear the area below the
speakers. Use roping or lateral spanning to effectively prevent motion build-up of flying speak-
ers. 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 bft, be sure to get down and uninstall flying speakers.
