Unpacking
Please make sure that there are no obvious transport
damages. Should you notice any damages on the
connection panel or on the casing, do not take the
speaker system into operation and immediately consult
your local dealer.
Protection Class
This device falls under protection class I. The power
plug must only be plugged into a protection class I
outlet. The voltage and frequency must exactly be the
same as stated on the device. Wrong voltages or power
outlets can lead to the destruction of the device and to
mortal electrical shock.
Power Cord
Always plug in the power plug least. The power plug
must always be inserted without force. Make sure that
the plug is tightly connected with the outlet. Never let
the power cord come into contact with other cables!
Handle the power cord and all connections with the
mains with particular caution! Never touch them with
wet hands, as this could lead to mortal electrical shock.
Never modify, bend, strain mechanically, put pressure
on, pull or heat up the power cord. Never operate next
to sources of heat or cold. Disregard can lead to power
cord damages, fire or mortal electrical shock. The cable
insert or the female part in the device must never be
strained. There must always be sufficient cable to the
device. Otherwise, the cable may be damaged which
may lead to mortal damage. Make sure that the power
cord is never crimped or damaged by sharp edges.
Check the device and the power cord from time to time.
If extension cords are used, make sure that the core
diameter is sufficient for the required power
consumption of the device. All warnings concerning the
power cords are also valid for possible extension cords.
Always disconnect from the mains, when the device is
not in use or before cleaning it. Only handle the power
cord by the plug. Never pull out the plug by tugging the
power cord. Otherwise, the cable or plug can be
damaged leading to mortal electrical shock. If the power
plug or the power switch is not accessible, the device
must be disconnected via the mains.
If the power plug or the device is dusty, the device must
be taken out of operation, disconnected and then be
cleaned with a dry cloth. Dust can reduce the insulation
which may lead to mortal electrical shock. More severe
dirt in and at the device should only be removed by a
specialist.
Liquids
There must never enter any liquid into power outlets,
extension cords or any holes in the housing of the
device. If you suppose that also a minimal amount of
liquid may have entered the device, it must immediately
be disconnected. This is also valid, if the device was
exposed to high humidity. Also if the device is still
running, the device must be checked by a specialist if
the liquid has reduced any insulation. Reduced
insulation can cause mortal electrical shock.
Foreign Objects
There must never be any objects entering into the
device. This is especially valid for metal parts. If any
metal parts like staples or coarse metal chips enter into
the device, the device must be taken out of operation
and disconnected immediately. Malfunction or short-
circuits caused by metal parts may cause mortal
injuries.
Avoiding Hum
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.
Prior to Switching on
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.)
Children and Amateurs
Keep away children and amateurs!
Maintenance and Service
There are no serviceable parts inside the speaker
system. Maintenance and service operations are only to
be carried out by authorized dealers!
