Safety
DANGER!
-
Risk of injury and choking hazard for children!
Children can suffocate on packaging material and small parts. Children can injure themselves when handling the device. Never allow children to play with the packaging material and the device. Always store packaging material out of the reach of babies and small children. Always dispose of packaging material properly when it is not in use. Never allow children to use the device without supervision. Keep small parts away from children and make sure that the device does not shed any small parts (such knobs) that children could play with. -
Danger to life due to electric current!
Within the device there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts inside. Do not use the device when covers, safety equipment or optical components are missing or damaged. -
Danger to life due to electric current!
A short circuit could lead to a fire hazard and risk of death. Always use proper ready-made insulated triple-core mains cable with a safety plug. Do not modify the mains cable or the plug. In case of isolation damage, disconnect immediately the power supply and arrange repair. If in doubt, seek advice from a qualified electrician.
WARNING!
Possible hearing damage due to operating the device at a high volume!
The device can produce volume levels that, when operated at a high volume, may
cause temporary or permanent hearing impairment. Over an extended period of
time, even levels that seem to be uncritical can cause hearing damage. Avoid
operating the device at excessively high volumes over an extended period of
time. Decrease the volume level immediately if you experience ringing in your
ears or hearing impairment. If this is not possible, keep a greater distance
or use adequate ear-muffs.
NOTICE!
-
Risk of fire due to covered vents and neighbouring heat sources!
If the vents of the device are covered or the device is operated in the immediate vicinity of other heat sources, the device can overheat and burst into flames. Never cover the device or the vents. Do not install the device in the immediate vicinity of other heat sources. Never operate the device in the immediate vicinity of naked flames. -
Damage to the device if operated in unsuitable ambient conditions!
The device can be damaged if it is operated in unsuitable ambient conditions. Only operate the device indoors within the ambient conditions specified in the “Technical specifications” chapter of this user manual. Avoid operating it in environments with direct sunlight, heavy dirt and strong vibrations. Avoid operating it in environments with strong temperature fluctuations. If temperature fluctuations cannot be avoided (for example after transport in low outside temperatures), do not switch on the device immediately. Never subject the device to liquids or moisture. Never move the device to another location while it is in operation. In environments with increased dirt levels (for example due to dust, smoke, nicotine or mist): Have the device cleaned by qualified specialists at regular intervals to prevent damage due to overheating and other malfunctions. -
Damage to the device due to high voltages!
The device can be damaged if it is operated with the incorrect voltage or if high voltage peaks occur. In the worst case, excess voltages can also cause a risk of injury and fires. Make sure that the voltage specification on the device matches the local power grid before plugging in the device. Only operate the device from professionally installed mains sockets that are protected by a residual current circuit breaker (FI). As a precaution, disconnect the device from the power grid when storms are approaching or it the device will not be used for a longer period.
Risk of fire due to installation of a wrong fuse!
Using fuses of a different type than compatible with the device may cause a fire and seriously damage the device. Only use fuses of the same type. Observe the labelling on the device casing and the information in the “Technical data” chapter. -
Possible staining due to plasticiser in rubber feet!
The plasticiser contained in the rubber feet of this product may react with the coating of the floor and cause permanent dark stains after some time. If necessary, use a suitable mat or felt slide to prevent direct contact between the device’s rubber feet and the floor.

Installation and starting up
Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively. Create all connections while the device is off. Use the shortest possible high-quality cables for all connections. Take care when running the cables to prevent tripping hazards.
WARNING!
-
Risk of injury from falling speakers that were inadequately secured!
If speakers are not properly secured when mounted, they can cause severe injury and considerable damage by falling. Always secure portable sound systems (speakers) with two independent safety devices, for example with safety cables. -
Risk of injury due to improper installation!
Improper mounting can lead to serious injuries and significant damage to property. When installing and operating, make sure to follow the standards and regulations that apply in your country. In Germany, this is DGUV regulation 17 “Staging and Production Facilities for the Entertainment Industry”. Ensure that speakers are only mounted by trained specialists.
NOTICE!
- Possible property damage to adjacent devices due to magnetic fields. Speakers generate a static magnetic field. This magnetic field can affect other neighbouring units and in unfavorable cases damage them. Ensure that speakers are always a sufficient distance away from sensitive equipment that may be affected by an external magnetic field.
- Potential property damage due to unsuitable stands!
If the device is mounted on an unsuitable stand, there is a risk that the stand will fall over and cause damage. Only use stands whose maximum bearing capacity is at least as high as the weight of the device. Always ensure that the stand is stable.
Tips on handling speakers
We recommend you to set up the speakers in a way, that the sound signals
can reach the audience unobstructedly. It will often be helpful to mount the
speakers on tripods. Thus, the sound will be evenly spread with maximum range
throughout the audience area. Always use high grade cable to connect your
equipment. Otherwise, you won’t reach maximum sound quality. If you notice
distortion during operation, the active speaker is overloaded. This may
permanently damage the device. Always reduce the volume as soon as you hear
distortion.

Plug and connection assignment
Introduction
This chapter will help you select the right cables and plugs to connect
your valuable equipment in such a way that a perfect sound experience is
ensured. Please note these advices, because especially in ‘Sound & Light’
caution is indicated: Even if a plug fits into the socket, an incorrect
connection may result in a destroyed power amp, a short circuit or ‘just’ in
poor transmission quality!
Balanced and unbalanced transmission
Unbalanced transmission is mainly used in semi-professional environment and
in hifi use. Instrument cables with two conductors (one core plus shielding)
are typical representatives of the unbalanced transmission. One conductor is
ground and shielding while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference,
especially at low levels, such as microphone signals and when using long
cables. In a professional environment, therefore, the balanced transmission is
preferred, because this enables an undisturbed transmission of signals over
long distances. In addition to the conductors ‘Ground’ and ‘Signal’, in a
balanced transmission a second core is added. This also transfers the signal,
but phase-shifted by 180°. Since the interference affects both cores equally,
by subtracting the phase-shifted signals, the interfering signal is completely
neutralized. The result is a pure signal without any noise interference.
