2 Safety instructions
Use the device only as described in this user manual. Any other use or use under other oper‐
ating 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.
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.
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
With loudspeakers or headphones connected, the device can produce volume
levels that may cause temporary or permanent hearing impairment.
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.
CAUTION!
Risk of injury due to heavy weight
Due to the heavy weight of the device, at least two persons are required for trans‐
port and installation.

NOTICE!
Risk of fire
Do not cover the device nor any ventilation slots. Do not place 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.

3 Installation and starting up
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.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
DANGER!
Electric shock caused by high voltages at the power amplifier output
The output voltages of modern high-performance amplifiers may result in death
or serious injury.
Never touch the bare ends of loudspeaker cables when the amplifier is on.

Depending on the individual application, the amplifier can be used in different operation
modes:
Stereo mode
The two amplifier channels operate independently of one another, either
channel (A and B) is amplified and connected to loudspeakers, the volume can
be controlled separately for the two outputs.
Parallel mode
The two amplifier channels receive the same input signal from channel A and
loudspeakers are connected to each amplifier. The volume is controlled via the
control knob for channel A.
Bridged mode
The two amplifier channels are internally connected in such a way that twice
the output power is available. Only the input signal from channel A is amplified
and loudspeakers are connected only to the correspondingly marked output.
The volume is controlled via the control knob for channel A.

For each output of the amplifier, the total impedance resulting from the loudspeakers con‐
nected to it must not be below the allowed minimal impedance of the amplifier output. If you
connect more than one loudspeaker to an amplifier output, please note the following:
nIf the loudspeakers are connected in a series, the individual impedances will be added up.
nIf the loudspeakers are connected in parallel, the reciprocal of the total impedance equals
the sum of the reciprocals of the individual impedances.
Example: If you have two loudspeakers with the same impedance, their impedance doubles if
they are connected in a series, their impedance halves if they are connected in parallel.
