OPERATING DETERMINATIONS
The active subwoofers PAS-151A and PAS-181A are equipped with high-capability 38 cm and 45 cm bass
speakers respectively and serve for subwoofer completion of full-range speakers (e.g. of the PAS series) in
PA systems. The speaker systems are equipped with a class D power amplifier (1000 W and 1200 W max.)
and an adjustable low-pass filter. The units offer combined XLR and 6.3 mm inputs with XLR parallel outputs
and are protected against overload and overcurrent. With the M20 flange and a distance tube (accessory), it
is possible to mount another speaker system on top of subwoofers. The subwoofers are suitable for various
mobile applications.

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.
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.
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. 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
device is never exposed to the direct smoke jet and is
installed in a distance of 0.5 meters between smoke
machine and device.
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! This speaker system
must only be installed at a solid, plane, anti-slip,
vibration-free, oscillation-free and fire-resistant location.
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!
Transport
Please use the original packaging if the device is to be
transported.
Cleaning
Never use solvents or aggressive detergents in order to
clean the device! Rather use a soft and damp cloth.
Serial Barcode
Never remove the serial barcode from the device as
this would make the guarantee void.
Modifications and Guarantee
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.
