Safety Instructions
Mounting the Speakers / Wall and Ceiling Installation
Suspended loads are safety related.
The speakers may only be mounted by qualified event technicians or personnel which are
instructed by them, adequately. This also applies for wall and ceiling fixations.
Warning
The technicians responsible for assembling the speakers on site are responsible for the safe
setup and use of the speakers and guarantee the safe use of the mounting elements.
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, the stability and type of the construction of walls, ceilings and panelling. If there is
wall panelling, for example, it is then necessary to examine the solidity of the wall and use
the appropriate wall plugs.
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.
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 safety-relevant components of the speaker
and the accessory 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.
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.
Warning
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.

K&F GRAVIS 12+
Protecting the Speakers / Operating Safety
GRAVIS 12+ speakers may only be used in combination with a K&F 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
•
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 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.
Suspending the Speakers
By using the K&F 'Lifting Pin' or the M10 x 17 eyebolts available as optional accessories from
Kling &Freitag, you can fly the speaker.

Wiring instructions
•
Before connecting your GRAVIS 12+ 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 (Ohm))
•
For connections to the power amplifier inputs, please use 2-pin shielded microphone
cable (balanced) with high-quality connectors.
KLING & FREITAG GMBH © 2014
Version 3.4
Page 17 of 29
User's manual
K&F GRAVIS 12+
•
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(Ohm) is not lower than the minimal impedance indicated on the power
amplifier.
1/R1 + 1/R2 + 1/R3 + ... = 1/Rtotal
9.
Operating the Speakers
•
Switch off all equipment and turn down all level controls of the mixing console and the
power amplifiers.
•
Wire your GRAVIS 12+ 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.
10. Transport and Storage
The GRAVIS 12+ is protected against short-term moisture. The accessories has to be stored,
transported and used in a dry enviroment. The GRAVIS 12+ System is not designed for longterm 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 GRAVIS 12+ 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.

11. Maintenance and Care
1.
For the owner and user, it is mandatory to be aware of the safety relevance of speakers
that can be flown.
Please note that the mains cables are delivered with varying connector options or with
open wires (mains side), depending on the country or order number.
Warning
The GRAVIS 12+ 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 accessory every time you suspend it and
take it down. GRAVIS 12+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 accessory 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.
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
3.
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.

15. Disposal
Please recycle the packaging material of the device.
15.1
Germany
It is not allowed to dispose of used electrical equipment as domestic waste.
But please do not dispose of them at official collecting points for recycling either!
All KLING & FREITAG products are plain business-to-business (B2B) products. KLING & FREITAG
products labelled with a waste bin sign have thus to be disposed of by KLING & FREITAG
GmbH alone. Please call KLING & FREITAG at the number stated below if you have a KLING
& FREITAG product to be disposed of. We will offer you a straightforward and professional
disposal with no costs involved.
If there is no waste bin sign on one of your KLING & FREITAG products, because it has been
sold before 24 March 2006, then by law the owner is in charge of the disposal. In this case we
will be happy to assist and offer you proper ways of disposal.
Telephone number to call about the disposal of used KLING & FREITAG products: +49 (0)
511-96 99 7-0
Explanation: With the ElektroG (law relating to electrical and electronic equipment and
appliances) we have complied with the EU-directive on waste electrical and electronic
equipment (WEEE, 2002/96/EC).
From 03/24/2006 onwards KLING & FREITAG GMBH has thus labelled all products mentioned
in the WEEE with a sign with a crossed out waste bin and a white bar below. This sign
indicates that the disposal as domestic waste is prohibited and that the product has been put
into circulation on 03/24/2006 at the earliest.
KLING & FREITAG GMBH has been legally registered as a manufacturer with the German

products.
15.2
EU, Norway, Iceland, and Liechtenstein
It is not allowed to dispose of used electrical equipment as domestic waste.
From 08/13/2005 onwards KLING & FREITAG GMBH has thus labelled all products for EUMember countries as well as Norway, Iceland and Liechtenstein (except Germany) mentioned
in the WEEE with a sign with a crossed out waste bin and a white bar below.
This sign indicates that the disposal on domestic waste is prohibited and that the product has
been put into circulation on 08/13/2005 at the earliest.
Unfortunately the European directive WEEE has been complied with implementing different
national provisions of law throughout all member countries, which makes it impossible for us
to offer consistent solutions for the disposal throughout Europe.
Responsible for complying with these provisions of law is the local distributor (importer) of
each country.
For proper disposal of used products in accordance with these local provisions in the
mentioned countries of the European Union (except Germany) please ask your local dealer or
the local authorities.
15.3
All other Countries
For proper disposal of used products in accordance with local provisions in other than the
above mentioned countries please ask your local dealer or the local authorities.
