2 Safety instructions
This device amplifies electric audio frequency signals to operate passive speakers. Use the
device only as described in this user manual. Any other use or use under other operating con-
ditions 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

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 pro-
tective contact plug. 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 regis-
tered electrician.

CAUTION!
Possible hearing damage
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.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi-
cient 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.
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!
Magnetic fields
The device generates strong magnetic fields that can interfere with the function
of poorly shielded devices. The strongest magnetic fields are directly above and
below the power amplifier. Therefore, never place sensitive devices such as pre-
amplifiers, radio transmission systems, or tape decks directly above or below the
power amplifier. When installing the power amplifier into a rack, you should place
it in the lowest position, and further equipment such as pre-amplifiers in the
highest position.
NOTICE!
Possible staining
The plasticiser contained in the rubber feet of this product may possibly react
with the coating of your parquet, linoleum, laminate or PVC floor and after some
time cause permanent dark stains.
In case of doubt, do not put the rubber feet directly on the floor, but use felt-pad
floor protectors or a carpet.
