This device is intended to be used for amplification, mixing and playback of signals from musical instruments and microphones. 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!
Risk of injury and choking hazard for children!
Children can suffocate on packaging material and small parts. Children can
injure themselves when handling the device. Never allow children to play with
the packaging material and the device. Always store packaging material out of
the reach of babies and small children. Always dispose of packaging material
properly when it is not in use. Never allow children to use the device without
supervision. Keep small parts away from children and make sure that the device
does not shed any small parts (such knobs) that children could play with.
DANGER!
Danger to life due to electric current!
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 when covers, safety equipment or optical components are missing or
damaged.
DANGER!
Danger to life due to electric current!
A short circuit could lead to a fire hazard and risk of death. Always use
proper ready-made insulated triple-core mains cable with a safety plug. Do not
modify the mains cable or the plug. In case of isolation damage, disconnect
immediately the power supply and arrange repair. If in doubt, seek advice from
a qualified electrician.
WARNING!
Possible hearing damage due to high volumes on speakers or headphones!
With speakers or headphones 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
impairment.
NOTICE!
Risk of fire due to covered vents and neighbouring heat sources!
If the vents of the device are covered or the device is operated in the
immediate vicinity of other heat sources, the device can overheat and burst
into flames. Never cover the device or the vents. Do not install the device in
the immediate vicinity of other heat sources. Never operate the device in the
immediate vicinity of naked flames.
NOTICE!
Damage to the device if operated in unsuitable ambient conditions!
The device can be damaged if it is operated in unsuitable ambient conditions.
Only operate the device indoors within the ambient conditions specified in the
“Technical specifications” chapter of this user manual. Avoid operating it in
environments with direct sunlight, heavy dirt and strong vibrations. Avoid
operating it in environments with strong temperature fluctuations. If
temperature fluctuations cannot be avoided (for example after transport in low
outside temperatures), do not switch on the device immediately. Never subject
the device to liquids or moisture. Never move the device to another location
while it is in operation. In environments with increased dirt levels (for
example due to dust, smoke, nicotine or mist): Have the device cleaned by
qualified specialists at regular intervals to prevent damage due to
overheating and other malfunctions.
NOTICE!
Damage to the device due to high voltages!
The device can be damaged if it is operated with the incorrect voltage or if
high voltage peaks occur. In the worst case, excess voltages can also cause a
risk of injury and fires. Make sure that the voltage specification on the
device matches the local power grid before plugging in the device. Only
operate the device from professionally installed mains sockets that are
protected by a residual current circuit breaker (FI). As a precaution,
disconnect the device from the power grid when storms are approaching or it
the device will not be used for a longer period.
NOTICE!
Risk of fire due to installation of a wrong fuse!
Using fuses of a different type than compatible with the device may cause a
fire and seriously damage the device. Only use fuses of the same type. Observe
the labelling on the device casing and the information in the “Technical data”
chapter.
NOTICE!
Possible staining due to plasticizer in rubber feet!
The plasticiser contained in the rubber feet of this product may react with
the coating of the floor and cause permanent dark stains after some time. If
necessary, use a suitable mat or felt slide to prevent direct contact between
the device’s rubber feet and the floor.

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.
