Safety instructions
Intended use
This device is intended to be used for the amplification of signals from
musical instruments with electromagnetic pickups. Use the device only as
described in this user manual. Any other use or use under other operating
conditions is considered to be improper and may result in personal injury or
property damage. No liability will be assumed for damages resulting from
improper use.
This device may be used only by persons with sufficient physical, sensorial,
and intellectual abilities and having corresponding knowledge and experience.
Other persons may use this device only if they are supervised or instructed by
a person who is responsible for their safety.
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 fire. If in doubt, seek advice from a registered
electrician.
CAUTION!
Possible hearing damage
With loudspeakers connected, 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. Do not operate the device permanently at a high volume
level. Decrease the volume level immediately if you experience ringing in your
ears or hearing impair‐ ment. If this is not possible, keep a bigger distance
to the speaker 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!
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!
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 fire.
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 necessary, i.e. felt pads or similar.

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.

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.
