Safety
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
Do not modify the mains cable or the plug. Failure to do so could result in electric shock/death or re. 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 sucient ear protectors.
CAUTION!
Possible hearing damage
Using headphones for a prolonged period and at high volume can cause hearing damage. Avoid using the device at high volume,
especially when using headphones.
NOTICE!
Risk of re
Do not block areas of ventilation. Do not install the device near any direct heat source. Keep the device away from naked ames.
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 specied in the chapter
‘Technical specications’ of this user manual. Avoid heavy temperature uctuations and do not switch the device on immediately
after it was exposed to temperature uctuations (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
qualied service personnel at regular intervals to prevent overheating and other malfunction.

NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC
outlet is protected by a residual current circuit breaker. Failure to do so could result in damage to the device and possibly injure the
user. Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric
shock or re.
NOTICE!
Possible staining
The plasticiser contained in the rubber feet of this product may possibly react with the coating of your surface and after some time
cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the surface and use a suitable underlay if neces‐
sary, i.e. felt pads or similar.

4 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 o. 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 elds
Loudspeakers produce a static magnetic eld. Therefore, maintain an appropriate
distance to devices that can be adversely aected or damaged by an external
magnetic eld.

7 Plug and connection assignment
This chapter will help you select the right cables and plugs to connect your valuable equip‐
ment 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 ts into the socket, an incorrect connection may result in a destroyed power amp, a short
circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hi 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 trans‐
mitted 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 conduc‐
tors ‘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 aects both cores equally, by subtracting the phase-shifted signals, the
interfering signal is completely neutralized. The result is a pure signal without any noise inter‐
ference.
