OPERATING DETERMINATIONS
The speaker systems of the CSA series are high-performance active speaker systems in light-weight and
high-impact polystyrene cabinets (HIPS). They can be flexibly used for permanent installations and touring
purposes. The speakers are designed as 2-way systems with Class D biamp power amplifiers for the bass
speaker and tweeter ranges. Model CSA-115CXA (MDF housing) serves for subwoofer completion of the
two full-range speakers. The subwoofer is equipped with a high-capability 38 cm (15″) bass speaker and
supplies a power of 1000 W. All amplifiers are equipped with limiters and protective circuits against overload,
overheating and short circuit.
Power Supply
Models CSA-218A and CSA-228A are allowed to be
operated with an alternating current of 100-240 V,
50/60 Hz; model CSA-115CXA is restricted to 230 V, 50
Hz. The units were designed for indoor use only. The
occupation of the connection cables is as follows:
Cable
Pin
International
Brown

N
Yellow/Green
Earth
The earth has to be connected! If the device will be
directly connected with the local power supply network,
a disconnection switch with a minimum opening of 3
mm at every pole has to be included in the permanent
electrical installation. The device must only be
connected with an electric installation carried out in
compliance with the IEC standards. The electric
installation must be equipped with a Residual Current
Device (RCD) with a maximum fault current of 30 mA.
Installation
Do not shake the device. Avoid brute force when
installing or operating the device. 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!
Ambient Conditions
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. When using smoke machines, make sure that
the device is never exposed to the direct smoke jet and
is installed in a distance of 0.5 meters between smoke
machine and device. 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.
Operation
Operate the device only after having familiarized with its
functions. Do not permit operation by persons not
qualified for operating the device. Most damages are
the result of unprofessional operation!
Cleaning
Never use solvents or aggressive detergents in order to
clean the device! Rather use a soft and damp cloth.
Transport
Please use the original packaging if the device is to be
transported.
Serial Barcode
Never remove the serial barcode from the device as
this would make the guarantee void.
Modifications and Guarantee
Please note that damages caused by manual
modifications on the device or unauthorized operation
by unqualified persons are not subject to warranty.
If this device 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 short-circuit, burns, electric shock, etc.
Avoiding Hearing Loss
By operating amplifying systems, you can produce
excessive sound pressure levels that may lead to
permanent hearing loss. Please refer to the
explanations under "Legal instructions".
Public and Industrial Use
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.
Maximum Power
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.
