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 fire. If in doubt, seek advice from a registered 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 transport and installation.

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 preamplifiers, 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.
Create all connections while the device is off. Use the shortest possible high-quality cables for
all connections. Take care when running the cables to prevent tripping hazards.
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
Both power amp channels are internally wired for providing double the output
power. 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.

On each output of the amplifier, the overall impedance resulting from the individual impedances of the connected speakers must not fall below the minimum allowable impedance of
the amp's output. If you want to connect multiple speakers to one amplifier output, note the
following:
n
when connecting speakers in series, the impedances add up.
n
when connecting speakers in parallel, the reciprocal value of the total impedance is equal
to the sum of the reciprocal values of the individual impedances.
This means, for example with two speakers with the same impedance: In series connection,
impedance is doubled. In parallel connection, it's halved.
Detailed information on this topic can be found in our online guide ‘Speakers’
(www.thomann.de).

6 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 fits 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 hifi use.
Instrument cables with two conductors (one core plus shielding) are typical representatives 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 affects 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.
