2 Safety instructions
This device is intended to be used for amplication, 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 sucient physical, sensorial, and intel‐
lectual 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.
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 re. If in
doubt, seek advice from a registered electrician.
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.

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.
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 pro‐
tected 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!
Danger of short circuit
Switching on phantom power will damage the device if unbalanced XLR
cables are connected.
Only turn on phantom power when exclusively balanced XLR cables are
connected.
Unpack and carefully check that there is no transportation damage before using the
unit. Keep the equipment packaging. To fully protect the device 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.

8 Plug and connection assignment
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 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 rep‐
resentatives 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 aects 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.
