OPERATING DETERMINATIONS
The portable PA system
COMBO-500
is a combination of a detachable 8-channel mixer and a 500 W
stereo amplifier. The system includes two speaker systems with the matching connection cables. The mixer
is provided with a digital effect processor for creating echo effects as well as a switchable dynamic processor
and bass boost.
The PA system is allowed to be operated with an alternating current of 115/230 V, 50/60 Hz and was
designed for indoor use only.
Operating an amplification 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.
The maximum power of the PA 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.
When choosing the installation spot, please make sure that the device is not exposed to extreme heat,
moisture or dust. There should not be any cables lying around. You endanger your own and the safety of
others! This speaker system must only be installed at a solid, plane, anti-slip, vibration-free, oscillation-free
and fire-resistant location.
This device must never be operated or stockpiled in surroundings where splash water, rain, moisture or fog
may harm the device. Moisture or very high humidity can reduce the insulation and lead to mortal electrical
shocks.
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 device must only be operated in an altitude between -20 and 2000 m over NN.
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.
Operate the PA 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!
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.
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.
