Ambient Conditions
•
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.
•
Never use the device during thunderstorms. Over
voltage
could
destroy
the
device.
Always
disconnect the device during thunderstorms.
•
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.
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!
•
Never install the amplifier next to highly sensitive
devices like pre-amplifiers or tape decks, as the
strong magnetic field of the amplifier can produce
hum in these devices. The magnetic field is
strongest directly above or below the amplifier. If a
rack is used, the amplifier should be installed at the
bottom and the highly sensitive devices at the top.
Commercial Use
•
Operating an amplification system in public or
industrial areas, a series of safety instructions have
to be followed. The operator must therefore inform
himself on the current safety instructions and
consider them.
Setup
•
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!
•
Before the unit is switched on all faders and
volume controls have to be set to zero or minimum
position. Turn the amplifier on last and off first!
Only connect the device when the power switch is
off. Never connect output to output. Never connect
the inputs or outputs to any power source
(batteries, etc.)
Cleaning and Service
•
Disconnect from mains before cleaning! Never use
solvents or aggressive detergents in order to clean
the device! Rather use a soft and damp cloth.
•
There are no serviceable parts inside the device
except for the fuse. Maintenance and service
operations are only to be carried out by authorized
dealers! Should you need any spare parts, please
use genuine parts.
Modifications and Guarantee
•
Never remove the serial barcode from the device
as this would make the guarantee void.
•
Please consider that unauthorized modifications on
the speaker system are forbidden due to safety
reasons!
•
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.
Maximum Power
•
The given maximum power of the speaker system
describes short-term peaks the system can handle
as a maximum. The correspondent RMS power is -
as of all comparable systems (also from other
manufacturers) - significantly lower. 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.
Intended Use
The PA amplifier has been specially designed for
fixed installations. Four individually controllable
channels are available for four speaker zones. The
amplifier and the connected loudspeakers are
protected by extensive protective circuits.
