3. Safety Instructions
3.1 Mounting the Speakers / Wall and Ceiling Installation
Suspended loads pose a safety risk. Only qualified technicians are permitted to perform the installation steps. Be sure to use personal protective equipment at all times. The technicians installing the speaker on site are responsible for and guarantee safe setup and use. Never use signal cables or power cords for suspending, aligning, or securing the systems. Before installing, check the stability, strength, and materials of walls, ceilings, and boarding. For example, use suitable rawlplugs for wall panels and make sure the strength is sufficient. Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or chain hoists) must comply with the DGUV regulations 17 and 18 or similar locally applicable accident-control standards. The maximum load must have been certified by an authorized expert. Be sure to tighten all bolts and screws to the specified torque. 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). Make sure all fittings used are suitable for the task at hand and meet all relevant safety requirements. 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. Be sure to always visually inspect all safety-related speaker and accessory components before use. If there are signs of wear, cracks, or deformation, etc., replace the affected parts immediately. Visual inspection also includes checking all screwed connections of supporting components. 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. 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.
3.3 Preventing Hearing Damage
Keep your distance from operating speakers. This equipment is capable of delivering sound pressure levels in excess of 90 dB SPL, which may cause permanent hearing damage.

3.4 Protecting the Speakers / Operating Safety

Version 4.3

Page 8 of 31

User’s Manual

K&F GRAVIS 12+

GRAVIS 12+ 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. 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. According to DGUV accident prevention regulations, a secondary safety component must be used when speakers are suspended with K&F LIFTING PINS. This secondary safety component must allow no drop.

Push the release button 1 and completely insert the lifting pin into the flying point 2.

Let go of the release button when you have completely inserted the bolt so that the release button pops back up. Ensure that you cannot pull out the lifting pin any more.

To fly the speakers or mount them on the wall or ceiling, we recommend using the accessory ‘Adjustable Speaker Mount GRAVIS 12’ or ‘U-Mount Wall / Ceiling Bracket GRAVIS 12’.
By using these accessories, you can easily adjust mounted speakers to the desired position.
Tip

4.1 Securing the Speakers (Secondary Safety Device)

5. Arrayed Speaker (Cluster)
If the loudspeaker are operated through K&F system controller, we recommend to use the ‘Top Low Cut’ switch for this operation. So you can optimize the frequency response for this application. When operating the systems without any K&F system controller, you should decrease the frequencies below 300 Hz for 3-4 dB.

7. 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. Min. Wire Gauge (mm²) = Req. Cable Length (m) / (2xSpeaker Impedance (Ohm))
· For connections to the power amplifier inputs, use 2-pin shielded microphone cable (balanced) with high-quality connectors.
· Avoid creating ground loops.
· Be sure to note the pinouts shown in these user’s 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 wiring, ensure that the connected speaker channels are working in phase, for example, using a voltage tester. When the connected channels are used simultaneously, you can identify out-of-phase statuses by bass cancellation or midfrequency signals (e.g. voices) that cannot be located properly.
· If several loudspeakers are connected, the signal can be linked through parallel from one loudspeaker to the next. 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

8. First-time Use
· 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 these user’s 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 whether the audio is properly routed to the appropriate speakers. Make sure no noise is heard through those speakers. 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.

Version 4.3

Page 13 of 31

User’s Manual

K&F GRAVIS 12+

· 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.

9. Configuration and Connecting Diagram
9.1 Compatibility with GRAVIS 12
Do not combine GRAVIS 12 and GRAVIS 12+ in one setup, because these speakers are not acoustically compatible. Furthermore, separate Speaker Blocks are available for GRAVIS 12 and GRAVIS 12+. Make sure to use the correct Speaker Blocks in order to guarantee safe operations of the speakers and an optimal result. An ‘Upgrade Kit GRAVIS 12 to GRAVIS 12+’ is available and recommended for upgrading the GRAVIS 12 into a GRAVIS 12+. Ask your specialist dealer for more information.
9.2 Controller Mode ‘Full-Range’
If you want to operate the GRAVIS 12+ in fullrange mode, then select the LSBlock Gra-12N+FR for the GRAVIS 12+ N or the Gra-12W+FR for the GRAVIS 12+ XW.

Version 4.3

Page 14 of 31

User’s Manual

K&F GRAVIS 12+

Activate the filter Cluster for the top speakers via Filter B if you wish to operate several tops next to one another.

If you need a higher bass level, activate the filter BassBoost via Filter B for the top speakers.

9.2.1 Controller Mode with Subwoofer in Overlap Mode
In full-range mode, the speaker GRAVIS 12+ is compatible with all K&F subwoofers that are run in the 100 Hz mode.
This so-called ‘overlap mode’ can make sense for surround uses when the tops should transmit the complete frequency spectrum and the subwoofer is used as an ‘effect bass’.
In the overlap mode, the bass boost must not be switched on.

Version 4.3
