DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like)
from the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.
DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.
Do not use the device if covers, protectors or optical components are missing
or damaged.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a
protective contact plug. Do not modify the mains cable or the plug. Failure to
do so could result in electric shock/death or fire. If in doubt, seek advice
from a registered electrician.
CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears
or hearing impairment. If this is not possible, keep a greater distance or use
sufficient ear protectors.
NOTICE!
Risk of fire
Do not block areas of ventilation. Do not install the device near any direct
heat source. Keep the device away from naked flames.
NOTICE!
Risk of fire due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries.
Ensure that proper polarity is observed when inserting batteries.
NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy
dirt, and strong vibrations.
Only operate the device within the ambient conditions specified in the chapter
‘Technical specifications’ of this user manual. Avoid heavy temperature
fluctuations and do not switch the device on immediately after it was exposed
to temperature fluctuations (for example after transport at low outside
temperatures).
Dust and dirt inside can damage the unit. When operated in harmful ambient
conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained
by qualified service personnel at regular intervals to prevent overheating and
other malfunction.
NOTICE!
Possible damage by leaking batteries
Leaking batteries can cause permanent damage to the device.
Take batteries out of the device if it is not going to be used for a longer
period.
NOTICE!
Possible staining
The plasticiser contained in the rubber feet of this product may possibly
react
with the coating of your parquet, linoleum, laminate or PVC floor and after
some time cause permanent dark stains.
In case of doubt, do not put the rubber feet directly on the floor, but use
felt-pad floor protectors or a carpet.
NOTICE!
Possible damage due to installation of a wrong fuse
The use of different types of fuses can cause serious damage to the unit. Fire
hazard!
Only fuses of the same type may be used.

Installation and starting up
Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively.
Create all connections while the device is off. Use the shortest possible high-quality cables for all connections. Take care when running the cables to prevent tripping hazards.
NOTICE!
Possible property damage by magnetic fields
Loudspeakers produce a static magnetic field. Therefore, maintain an
appropriate distance to devices that can be adversely affected or damaged by
an external magnetic field.
The unit can be mounted on a tripod or set up on the floor or a sufficiently sized and stable surface, e.g. a wall bracket.
NOTICE!

Further information
Plug and connection assignment
Introduction
This chapter will help you select the right cables and plugs to connect your
valuable equipment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is
indicated: Even if a plug fits into the socket, an incorrect connection may
result in a destroyed power amp, a short circuit or ‘just’ in poor
transmission quality!
Balanced and unbalanced transmission
Unbalanced transmission is mainly used in semi-professional environment and in
hifi use. Instrument cables with two conductors (one core plus shielding) are
typical representatives of the unbalanced transmission. One conductor is
ground and shielding while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference,
especially at low levels, such as microphone signals and when using long
cables.
In a professional environment, therefore, the balanced transmission is
preferred, because this enables an undisturbed transmission of signals over
long distances. In addition to the conductors ‘Ground’ and ‘Signal’, in a
balanced transmission a second core is added. This also transfers the signal,
but phase-shifted by 180°.
Since the interference affects both cores equally, by subtracting the phase-
shifted signals, the interfering signal is completely neutralized. The result
is a pure signal without any noise interference.

1/4″ TRS phone plug (mono, balanced)
Three-pole 1/8″ mini phone jack (stereo, unbalanced)

Cleaning
Device components
Clean the device components that are accessible from the outside regularly.
The cleaning frequency depends on the operating environment: damp, smoky or
particularly dirty environments can cause greater accumulation of dirt on the
device components.
- Clean with a dry soft cloth.
- Stubborn dirt can be removed with a slightly dampened cloth.
- Never use solvents or alcohol for cleaning.
Protecting the environment
Disposal of the packaging material
For the packaging, environmentally friendly materials have been chosen that
can be supplied to normal recycling.
Ensure that plastic bags, packaging, etc. are properly disposed of.
Do not just dispose of these materials with your normal household waste, but
make sure that they are collected for recycling. Please follow the notes and
markings on the packaging.
Disposal of batteries
Batteries do contain some hazardous chemicals so they should not be thrown
away with the normal household waste. They should be returned to the
manufacturer for disposal or recycled elsewhere in accordance with your local
regulations.
Remove lithium batteries from the device before disposal. Protect used lithium
batteries against potential short circuits, e.g. by covering the poles with
adhesive tape. Dispose the built-in lithium batteries together with the
device. Please check for an appropriate reception facility.
Disposal of your old device
This product is subject to the European Waste Electrical and Electronic
Equipment Directive (WEEE) in its currently valid version. Do not dispose with
your normal household waste.
Dispose of this device through an approved waste disposal firm or through your
local waste facility. When discarding the device, comply with the rules and
regulations that apply in your country. If in doubt, consult your local waste
disposal facility.
