There are no serviceable parts inside the speaker system. Maintenance and service operations are only to be carried out by authorized dealers.
3. OPERATING DETERMINATIONS
This speaker system is an active system which can be used for permanent installations or for mobile use. This product is only allowed to be connected with an appropriate power amplifier and was designed for indoor use only.
The given maximum power of the speaker system describes short-term peaks the system can handle as a maximum. The correspondent RMS power is - as of all comparable systems (also from other manufacturers) - significantly lower. The maximum power of the speaker system must never be exceeded. When operating the speaker system, please make sure that the loudspeakers always sound well. When distortions can be heard, either the amplifier or the loudspeaker is overloaded. Overloads can quickly lead to amplifier or speaker damage. In order to avoid damage, please reduce the volume immediately when distortions can be heard. When speaker systems are destroyed by overload, the guarantee becomes void.
By operating speaker systems with an amplifier, you can produce excessive sound pressure levels that may lead to permanent hearing loss.
WARNING!
Speaker systems must only be operated by trained persons. Danger of Life due to crashing speaker systems or hearing loss due to excessive sound pressure levels! The different local conditions have to be considered in terms of safety rules.
This speaker system must never be operated or stockpiled in surroundings where splash water, rain, moisture or fog may harm the speaker system. When using smoke machines, make sure that the speaker system is never exposed to the direct smoke jet and is installed in a distance of 0.5 meters between smoke machine and speaker system.
The ambient temperature must always be between -5^ C and +45^ C. Keep away from direct insulation (particularly in cars) and heaters.
The relative humidity must not exceed 50 % with an ambient temperature of 45^ C.
This speaker system must only be installed at a solid, plane, anti-slip, vibration-free, oscillation-free and fire-resistant location.
English
Please note: when using this speaker system in public or industrial areas, a series of safety instructions have to be followed that this manual can only give in part. The operator must therefore inform himself on the current safety instructions and consider them.
Before installing the system, make sure that the installation area can hold a minimum point load of 5 times the system's load (e.g. weight 20 kg - point load 100 kg).
The speaker system must never be installed higher than 100 cm without secondary attachment.
The installation of the speaker system has to be built and constructed in a way that it can hold 10 times the weight for 1 hour without any harming deformation.
DANGER!
This speaker system must never be stacked - Danger to Life due to crashing speaker systems!
DANGER!
This speaker system must never be suspended - Danger to Life due to crashing speaker systems!
This speaker system can be installed on top of a subwoofer (satellite system), on a speaker stand, an appropriate stand or an appropriate wall-mounting. The carrying capacity of the distance-tube, the speaker stand, the stand or the wall mounting must never be exceeded.
The satellite system must always provide enough stability. Satellite systems are only allowed if the subwoofer's weight is twice as much as the top speaker's weight. Furthermore, the subwoofer's base surface must always be sufficiently dimensioned in relation to the top speaker in order to prevent tilting over.
Make sure that the area below the installation place is blocked when rigging, derigging or servicing the fixture.
Operate the speaker system only after having familiarized with its functions. Do not permit operation by persons not qualified for operating the speaker system. Most damages are the result of unprofessional operation!
This speaker system is not designed for road use. The speaker system is designed only for seldom transports. When transporting this speaker system, it must be moved carefully and without force.
Speaker systems must never be transported with cranes.
Never stack heavy objects on this speaker system. Persons must never climb onto this speaker system.
Never use solvents or aggressive detergents in order to clean the speaker system! Rather use a soft and damp cloth.
Please consider that unauthorized modifications on the speaker system are forbidden due to safety reasons!
If this speaker system will be operated in any way different to the one described in this manual, the product may suffer damages and the guarantee becomes void. Furthermore, any other operation may lead to dangers like crashes, hearing loss etc.
4. INSTALLATION
The speaker system can be set up as desired. The location must be solid, plane, anti-slip, vibration-free, oscillation-free, and fire-resistant. The installation area must hold a minimum point load of 5 times the system's load (e.g. weight 20 kg - point load 100 kg). The speaker system must never be installed higher than 100 cm without secondary attachment.
The speaker system can also be installed on a subwoofer, stand or wall mounting via the flange on the bottom.
The speaker system features two transportation handles. It should be carried without force by two persons of the same size. Carrying the speaker system by one person should be avoided as the high weight and the strain could lead to back damages and torsions. Please note that all speaker systems with more than 25 kg weight must be transported with two persons.
Installing and orienting the speaker system
When installing the speaker system on e.g. a stage, microphones and turntables should always be located behind the speaker systems. In this way, you can avoid dangerous and unpleasant feedback. If you cannot install the speaker systems this way, the microphones and turntables should be located as far away as possible from the speaker systems. When using the speaker system as monitor-system make sure to avoid feedback.
The speaker systems of a PA system are normally located left and right to the stage. Do not install the speaker systems on the stage, but rather on appropriate tables or platforms in front of the stage.
In order to produce a clear sound, the speaker systems should be installed in a way that they throw the sound over the audience's heads. A full-range speaker system should be installed at listeners' eye level. Please refer to the safety instructions under Installation.
Loudspeaker combinations need to be installed bass-middle-high (from bottom to top). Make sure that the membranes of all speakers are in one line vertically and horizontally. Only in this way all frequency ranges are produced at the same time and without any time or phase delays.
Always install the speaker systems in a way that a minimum distance of three meters to the audience is kept. This is the only way to avoid hearing damage for unreasonable listeners. Block the area in front of the speaker systems with appropriate means.
Avoiding feedback
One of the most frequent problems when operating speaker systems are feedback. They can be recognized by howling and growling loudspeakers. Feedback are created then a signal is recorded by a microphone, amplified, played back by a loudspeaker and then again recorded by the microphone.
The prerequisite for feedback is that the played back signal is louder than the original signal. A feedback never covers the whole frequency range but only one overboosted frequency.
Make sure that you install especially the monitor speakers so far away from the microphone that another recording of the microphone signal is impossible.
Extreme levels like feedback, bass-hum or the beats of a dropping microphone can destroy the loudspeakers within very short time and produce immediate hearing damage. Such extreme levels must be avoided at any rate. We recommend to use appropriate equalizers and compressors/limiters.
4.1 Stacking
DANGER!
This speaker system must never be stacked - Danger to Life due to crashing speaker systems!
This speaker system may only be installed on the floor or appropriate stage elements etc.

natural_image
Line drawing of a smart speaker with a screen and antenna, mounted on a stand (no text or symbols)A satellite system is a system where a speaker system with flange is installed on top of a subwoofer. The satellite system must always provide enough stability. The subwoofer's base surface must always be sufficiently dimensioned in relation to the top speaker in order to prevent tilting over.
The subwoofer and the top speaker must only be connected via an appropriate distance tube and flange.
The carrying capacity of the distance tube must never be exceeded.
A satellite system or a combination of speaker system/speaker stand or speaker system/stand must only be installed on the ground!
When choosing the installation spot, please make sure that such an installation has to be installed in a way that no person can enter three areas below the system! Make sure that the respective area is blocked.
An unintended movement of the load has to be avoided - also in case off fire! The installation is only allowed on carrying areas. In some cases, an appropriate substructure, e.g. via am balancing foot, has to be created.
The system must never be moved before the top speaker is uninstalled!
When choosing the installation material, optimum dimensions have to be chosen in order to secure maximum safety.

4.3 Installation on a stand or speaker stand
natural_image
Line drawing of a portable air conditioner stand with tripod base (no text or symbols)Stands or satellite systems must only be installed on a plume area with a maximum inclination angle of 5^ .
Caution: Speaker systems installed on stands or satellite systems may cause severe injuries when crashing!
When using stands or satellite systems under the influence of horizontal forces, e.g. through wind, the standing safety can be impaired. This is why additional safety measures like attaching ballast weights have to be taken.
If inclined tension cables or prolonged outriggers are used, the area of danger has to be marked or even be blocked.
Before lifting or lowering the telescopic tubes, you must always block a safety area around the stand or satellite system. This safety area must have a diameter of 1.5 times the maximum height.
Lifted telescopic tubes always have to be secured with a secondary securing!
The total weight of the installation (=total weight of all individual parts) must never exceed the maximum load of the installation area.
The stand has to be installed out of the reach of people.
An unintended movement of the load has to be avoided - also in case of fire!
The installer is responsible for adhering to the carrying capacity given by the manufacturer, the safety requirements and the qualification of possible co-workers.
When people are located below the load, all necessary safety measures have to be taken in order to avoid injury.
The personnel has to be instructed on the content of the user manual and on the dangers related with operating stands.
Depending upon the individual installation spot, all necessary measures against movement and for securing the standing safety have to be created.
The installation is only allowed on carrying areas. In some cases, an appropriate substructure, e.g. via an balancing foot, has to be created.
The system must never be moved before the top speaker is uninstalled!
When choosing the installation material, optimum dimensions have to be chosen in order to secure maximum safety.
Loosen the fixation screws of the legs. Pull the legs out until the cross struts stand at a 90^ angle to the legs. Tighten the fixation screws of the legs.
DANGER!
If installing on slippery surfaces, the legs must be secured with screws or nails via the provided holes or a anti-slippery mat has to be used.
Installation of the TV pin (only for stands)
Attach an appropriate TV pin to the top end of the stand and fasten it with the handle at the side.
Suitable TV pin: EUROLITE TV-35 TV-pin for speakers, No. 60000735

natural_image
Illustration of a wall-mounted smart water heater mounted on a pole (no text or symbols)Before attaching the speaker system, make sure that the installation area can hold a minimum point load of 5 times the speaker system's weight.
The wall mounting must be installed out of the reach of people.
The durability of the installation depends very much on the material used at the installation area (building material) such as wood, concrete, gas concrete, brick etc. This is why the fixing material must be chosen to suit the wall material. Always ask a specialist for the correct plug/screw combination indicating the maximum load and the building material.
The wall mounting must always be installed via all fixation holes. Do only use appropriate screws and make sure that the screws are properly connected with the ground.
The wall mounting's maximum service life must never be exceeded.
Procedure:
Step 1: On the wall-mounting, there are holes for the installation.
Step 2: Hold the wall mounting onto the location where it is to be installed.
Step 3: Mark the boreholes with a pen or a suitable tool.
Step 4: Drill the holes.
Step 5: Hold the wall mounting in the desired position and tighten the screws.
Step 6: Install the speaker on the wall-mounting.
4.5 Suspended installation
This speaker system must never be suspended - Danger to Life due to crashing speaker systems!
5. CONNECTIONS
5.1 Choosing an appropriate power amplifier
Connect this speaker system to an appropriate power amplifier, otherwise damage may occur. If several speakers are connected the impedance decreases correspondingly. Please make sure that the power amplifier is qualified for your intended use.
Example for the calculation number of speakers/impedance
| Number of speakers | Impedance |
| 1 speaker at 8 Ω8 Ω | |
| 2 speakers at 8 Ω each | 4 Ω (parallel) |
| 2 speakers at 8 Ω each | 16 Ω (in line) |
| 3 speakers at 8 Ω each | 2.66 Ω (parallel) |
| 3 speakers at 8 Ω each | 24 Ω (in line) |
| 4 speakers at 8 Ω each | 2 Ω (parallel) |
The input impedance of the speaker systems should at least be the same or even higher than the output impedance of the amplifier.
5.2 Making the connections
- If the PA system is turned on, turn it off before making any connection.
- The speaker system is equipped with lockable Speaker sockets. These are connected in parallel. For locking a connection turn the plug to the right. For unlocking pull the unlock button and turn the plug to the left and pull it out of the socket.
- Connect the input jack INPUT to the output of the amplifier.
- The feedthrough signal is present at the output jack LINK, e.g. for connecting the input of another speaker system.
Pin occupation of the Speaker jacks:
5.3 Information on installing audio cables
- Always treat cables carefully and protect them from damages during transportation.
• Install cables always in a structured way and protect them from damage. - Cables must be installed in a way that no person can stumble over them. Always fix cables with an appropriate tape.
- Cables should be installed directly (no loops, S-shaped overlengths).
- Always install cables far away from power cables (never closely parallel).
- Never put heavy objects like speaker systems, flightcases etc. on cables.
- Never operate cables wound up.
6. OPERATION
After having connected your speaker system, turn all level controls counterclockwise to the minimum position on the amplifier. The last device to be switched on is the amplifier. Now adjust the volume with the level controls.
During operation, please make sure the speaker always sounds well. When distortions can be heard, either the amplifier or the speaker is overloaded. Overloads can quickly lead to amplifier or speaker damage.
In order to avoid damage, please reduce the volume immediately when distortions can be heard. When speakers are destroyed by overload, the guarantee becomes void.
Always check the sound pressure level with a meter in order to keep to the threshold.
If you want to switch off the system, switch off the amplifier first and then the pre-amplifiers in order to avoid acoustic shocks on the speakers.
7. CLEANING AND MAINTENANCE
The operator has to make sure that safety-relating and machine-technical installations are inspected by an expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a skilled person once a year.
The following points have to be considered during the inspection:
1) All screws used for installing the speaker systems or parts of the speaker system have to be tightly connected and must not be corroded.
2) There must not be any deformations on housings, fixations and installation spots (ceiling, suspension, trussing).
3) The electric power supply cables must not show any damages, material fatigue (e.g. porous cables) or sediments. Further instructions depending on the installation spot and usage have to be adhered by a skilled installer and any safety problems have to be removed.
4) If the speaker system is installed overhead, the inspection must include if the eye-bolts are still well tightened. Otherwise the eye-bolts have to be tightened hand-tight again.
5) If the speaker system is secured via clamping belts, the inspection must include if the clamping belts are still well fixed. Otherwise fix clamping belts again.
We recommend a frequent cleaning of the speaker system. Please use a soft lint-free and moistened cloth. Never use alcohol or solvents!
There are no serviceable parts inside the speaker system. Maintenance and service operations are only to be carried out by authorized dealers.
If the speaker system distorts, one of the loudspeakers may be defective. Test the speaker system once more with another amplifier. If the sound remains distorted, the speaker system should not be operated any more in order to prevent further damage. Please contact your dealer.
If clacking sounds are heard from the speaker system, screws may have loosened due to the continuous vibrations. The speaker system should be checked by a specialist. Especially for public use, the speaker system should be checked before every operation so that the speaker system and the speakers in the systems are always well fixed.
Should you need any spare parts, please use genuine parts.
Should you have further questions, please contact your dealer.
