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 supervi‐

sion. 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.

Safety instructions

Power Amplier

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.

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 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 over‐

heat 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 sun‐

light, heavy dirt and strong vibrations. Avoid operating it in environments with strong temperature uctuations. If temperature uc‐

tuations 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 qualied specialists at reg‐

ular 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 vol‐

tages can also cause a risk of injury and res. Make sure that the voltage specication 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!

Interference with nearby electrical devices due to magnetic elds!

The device generates strong magnetic elds that can interfere with the function of poorly shielded devices. The magnetic elds are

strongest directly above and below the Power Amplier. You should therefore never place sensitive devices such as pre-ampliers,

radio transmission systems, or tape decks directly above or below the Power Amplier. When placing the Power Amplier in a rack,

you should place it at the bottom thereof, and place any other equipment at the top of the rack.
