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.
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 articular, 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.
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 Safety Instructions for Stacked Setups
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 system 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.
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 XLC you must always strap the speakers to one another and secure them from falling over.
3.2 Protecting the Speakers / Operating Safety
NOMOS XLC speakers may only be used in combination with a K&F SystemAmp/SystemRack.
System Requirements for Use
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 unnaturallydistorted.
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.

• where low air circulation (convection) prevails.

• that have a small distance to a wall.

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.
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.

NOMOS XLC combined with other K&F tops.

The NOMOS XLC can be combined with K&F top speakers using the controller K&F CD 44.

• To do so, select the desired LS blocks for the top in the Controller CD 44 or systemamp

TOPAS, and combine these with the desired LS block for the NOMOS XLC.
In the respective Hardware Manuals, you will find detailed descriptions about connecting the SEQUENZA 10 speakers and the settings necessary on the System Controller CD 44. SONA SUB

Stacking the Subwoofers

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.

You must additionally secure vertically standing stacked NOMOS XLC systems from falling since the structural safety is not guaranteed, otherwise.

Cardioid Arrays with Controller CD 44

The subwoofer NOMOS XLC is a cardioid loudspeaker.
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.

6.1 Setup instructions for a cardioid array
In order to implement a cardioid or hyper-cardioid setup, the fronts of the speakers must face the audience.
When cardioid speakers are put on the floor, ensure that there is always a distance of at least 40 cm between and over the speakers.
We recommend a safe distance to a possible obstruction of at least one meter (1 m). Distance at standing speakers: Distance at lying speakers: 6.2 LSBlocks for cardioid useNOMOS XLC
The following cardioid or hypercardioid setups are available in the K&F CD 44. All setups with a cutoff frequency other than 60 Hz have a cutoff frequency of 100 Hz.

Fuse in the NOMOS XLC

To increase the operating safety of the NOMOS XLC, 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).
7.1 Replacing the Fuses
The fuse holder is behind the rear chassis.
Replace the fuse with the following original fuse only:
Bussmann S 506-8A, T 250 V

Connection

The operating safety and the highest-possible performance is only guaranteed in conjunctionwith  the K&F Topas or K&F SystemRack.
8.1 Terminal assignment 8.2 Cabling a K &F System Rack 8.3 Connecting the NOMOS XLC
The following connecting diagram shows an example with the K&F CD 44 Routing ‘1 in 4 out’.
A maximum of 3 NOMOS XLC subwoofers can be driven by one K&F SystemRack. If you want to use 3 NOMOS XLC subwoofers with a K&F SystemRack you will need the Break Out Box ‘K&F BOB-C’ available as an accessory.
