Connection and getting started

below the selected frequency will be damped. This might be useful if the speaker has to play very loud (e.g. as small PA) without the need
of playing deep bass. So, there is more energy left for reproducing the mid-/high-range.
12.
Mains fuse: In the lower part of the mains inlet there is a drawer which contains the mains fuse. This drawer is
already equipped with a fuse which fits to the mains voltage of your local energy provider. If you would like to
connect the speaker to a different mains voltage, the voltage selector switch (13) has to be switched to the ap-
propriate mains voltage and the mains fuse has possibly to be adapted.
13.
Voltage selector switch: By means of this switch the appropriate mains voltage can be selected. The default
value is already corresponding to the mains voltage which is provided by your local energy provider and should
not be changed.
14.
Mains inlet: In the upper part of the mains inlet the female plug of the power cord (E) will be plugged-in. The
mains plug then should be plugged into an available mains receptacle.
15.
Mains switch: If all necessary connections are done, finally the mains switch can be switched on. A blue LED at
the front of the speaker will signalize that the speaker is working properly.

Selector switches for several sound adaptations: The AM 150 comes with 3 selector
switches for adapting the sound to special room conditions or to personal gusto. For
examples, please also refer to page 6.
The switch ACOUSTIC SPACE adjusts a so called shelving filter for the bass range. By
means of this filter room resonances, caused by e.g. close-to-the-wall locations, can be
equalized.
The switch HF TRIM is also a shelving filter which can be used or emphasizing (espe-
cially for extremely damped rooms) or damping the high frequency range.
The switch LF CUTOFF controls the cutoff frequency of a highpass filter. All frequencies
