2 Safety instructions
This device is intended to be used for amplication, 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 sucient 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.
Safety
DANGER!
Risk of injury and choking hazard for children!
Children can suocate 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!
A short circuit could lead to a re 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 qualied electrician.
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.
NOTICE!
Risk of re 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 ames. 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 ames.
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 specied in the “Technical specications” 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 uctuations. If
temperature uctuations 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 oper‐
ation. In environments with increased dirt levels (for example due to dust, smoke, nicotine or mist): Have the device cleaned by
qualied specialists at regular intervals to prevent damage due to overheating and other malfunctions.
NOTICE!
Risk of re due to installation of a wrong fuse!
Using fuses of a dierent type than compatible with the device may cause a re 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.

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.
The unit has been designed for rack mounting in a standard 19-inch rack; it occupies
one rack unit.
The gure schematically shows how the device can be controlled via a computer's
USB port.
