Setup and position of the unit
To reduce the risk of injury, extra care should be taken if the
unit is operated near children
Make sure that speakers are stable, especially when mounted
on stands. Never position speakers on an uneven or unstable
surface.
Do not operate this unit near water (e.g. wash basins,
swimming pools, very damp ground)
Keep the unit away from water, dust, places subject to long
periods of intensive sunshine and vibrations
Avoid setting up the unit near ovens, heaters or other
heat-generating devices or exposing it to extremely low
temperatures
When setting up the unit, make sure that ventilation is
adequate
Make sure that the unit cannot tip over or fall down and that
fluids cannot enter the unit through the ventilation slits.
Do not place receptables containing liquid on top of the
device. •

Connections and cables
Cables are the connecting links between all components in
a transmission chain, from microphones and instruments to
speakers. They are often underestimated in this function.
Please make sure that your cables function correctly
When purchasing cables, ensure that they are high-quality
cables with good connectors and that they cannot be damaged
by e.g. people walking on them
Make sure that the distributor for the mains voltage supply is
intact.
Using mains cables and distributors with insulated or missing
protective earth conductors is prohibited
Attention should also be paid when laying cables: asymmetric
cables should e.g. not be laid beside lighting cables. If
necessary, they should be crossed at right angles to keep the
risk of interference to a minimum
Cables should always be secured to the floor with gaffer tape
WARNING : Do not place any objects on the mains cable for the
unit. Only use mains cables that are intact
The unit should only be connected to a mains power supply if
the mains voltage corresponds to the one specified on the unit
Unplug the mains cable if the unit is not used for long periods.
When unplugging, do not pull on the cable, pull on the plug

Operation
Never exceed the total minimum load impedance of 8
ohms. You may only connect an 8-ohm speaker to the unit.
It is forbidden to connect a 4-ohm speaker
When used in combination with headphones or an amplifier,
this unit is capable of producing volumes that may cause
permanent damage to hearing. Do not expose your ears to
loud and potentially painful sounds for longer periods. If you
feel that your hearing is impaired or begin to hear whistling
sounds, consult a doctor.
During operation, speakers may be damaged by the following:
•
•
•
Acoustic feedback
Persistent high-level high-frequency signals from electronic
musical instruments
Persistent distorted high-output signals
Popping noises produced when a device in the system
is switched on, connected or disconnected while the
amplifier is switched on. a)
b)
c)
d)
Do not perform any work on the unit that extends beyond
general maintenance. Have all other service work carried out
by qualified service personnel, without exception.
Retain any original packaging in case the unit is damaged
and needs to be sent for repair. This will minimise the risk of
damage during transportation. •
