3. OPERATING DETERMINATIONS
This speaker for ceiling mounting was specially designed for application in PA systems. It is equipped with a
transformer for operation at 100 V systems, however, it can also be directly connected to an amplifier output
of low impedance. The speaker must only be used for permanent installations and is only allowed to be
connected with an appropriate amplifier. The power is matched via selection of cables. This product is
designed for indoor use only and must never be installed in damp rooms.
The maximum power of the speaker must never be exceeded. When operating the speaker, please make
sure that the loudspeakers always sound well. When distorsions 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 speakers 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. The ambient temperature must always be between -5° C and +45° C. The relative humidity
must not exceed 50 % with an ambient temperature of 45° C.
This product must only be operated in an altitude between -20 and 2000 m over NN.
The speaker must never be covered by insulation material, vapour foils or similar building material. Danger of
burning!
Operate the speaker only after having familiarized with its functions. Do not permit operation by persons not
qualified for operating the speaker. Most damages are the result of unprofessional operation!

cloth.
Please consider that unauthorized modifications on the speaker are forbidden due to safety reasons!
If this speaker will be operated in any way different to the one described in this manual, the product may
