7 Running-in period
Like any technical device, a loudspeaker must be run in, because there are slight
improvements in the acoustic characteristics of the loudspeaker. For example, if it
has been stored in a cool environment, it takes time until the damping components
and the suspension of the chassis regain their optimum mechanical properties. The
suspension of the drivers becomes more flexible during the first hours of operation.
The time required for the speaker to reach its optimum reproduction quality varies
depending on the history and treatment of the speaker. It may take up to a week for
the speakers to stabilize in the event of large temperature differences between
storage and commissioning. A minimum of 15 hours of operation is required before
the mechanical parts can perform their optimum function. An ambient temperature
that is as constant as possible ensures the reproduction quality of the loudspeaker.
(In DIN EN 60204-1, ambient temperature refers to the temperature of the air or
other medium in which equipment is used as intended. It is part of the physical
ambient and operating conditions, the non-observance of them may exclude a
warranty claim).

Connection to the mains supply
Before using the speakers, wait until their temperature has adjusted to room
temperature. Too large temperature differences cause condensation in the
electronics devices and in the loudspeaker, resulting in short circuits. This can lead to
considerable damage to the electronics devices and even up to burning loudspeakers.
The temperature adaption can take several hours, depending on how the speakers
were previously stored.
Power is supplied via a standard grounded power cable. The power plug at one end
of the cable is plugged into the power socket as usual, the other so-called Powercon
plug is connected to the blue input socket of the active module at the loudspeaker.
The Powercon plug can only be plugged into the socket in one orientation, after
connecting the plug turn it a quarter turn clockwise until it locks into place. This
ensures a secure connection with the device. To release, pull back the slider on the
plug and turn the plug a quarter turn to the left and pull it out of the socket.
The mains voltage may be in the range of 110 V to 230 V, and the power frequency
between 50 Hz and 60 Hz. The loudspeaker can be switched on and off with a
separate switch. After switching on, the processors are initialized and all components
are tested for function. Only then is the loudspeaker ready for operation.
