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 re. 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 su‐cient ear protectors.
NOTICE!
Risk of re
Do not block areas of ventilation. Do not install the device near any direct heat
source. Keep the device away from naked ames.

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.
Only operate the device within the ambient conditions specied in the chapter
‘Technical specications’ of this user manual. Avoid heavy temperature uctua‐tions and do not switch the device on immediately after it was exposed to tem‐
perature uctuations (for example after transport at low outside temperatures).
Dust and dirt inside can damage the unit. When operated in harmful ambient
conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by
qualied service personnel at regular intervals to prevent overheating and other
malfunction.

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 re.
NOTICE!
Possible damage due to installation of a wrong fuse
The use of dierent types of fuses can cause serious damage to the unit. Fire
hazard!
Only fuses of the same type may be used.

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.
WARNING!
Risk of injury caused by falling objects
Make sure that the installation complies with the standards and rules that apply
in your country. Always secure the device with a secondary safety attachment,
such as a safety cable or a safety chain.

Plug and connection assignment
Introduction
Balanced and unbalanced trans‐
mission
This chapter will help you select the right cables and plugs to connect your valuable equip‐
ment 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 ts 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 hi 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 trans‐
mitted 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 conduc‐
tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers
the signal, but phase-shifted by 180°.

XLR plug (balanced)
Since the interference aects both cores equally, by subtracting the phase-shifted signals, the
interfering signal is completely neutralized. The result is a pure signal without any noise inter‐
ference.
