2 Safety instructions
This device is primarily designed for monitoring during audio recording and mixing in the
studio. Use the device only as described in this user manual. Any other use or use under other
operating conditions is considered to be improper and may result in personal injury or prop-
erty 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

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.
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!
External power supply
The device is powered by an external power supply. Before connecting the
external power supply, ensure that the input voltage (AC outlet) matches the
voltage rating of the device and that the AC outlet is protected by a residual cur-
rent circuit breaker. Failure to do so could result in damage to the device and pos-
sibly the user.
Unplug the external power supply before electrical storms occur and when the
device is unused for long periods of time to reduce the risk of electric shock or
fire.

4 Installation
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.
NOTICE!
Possible property damage by magnetic fields
Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate
distance to devices that can be adversely affected or damaged by an external
magnetic field.

7 Plug and connection assignment
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 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 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°.
