About the X-Over
Frequency divider (X-Over):
This machine is equipp ed with an active
frequency divider. The frequency divider can
limit the frequency that reaches each output.
Each chan nel can be controlled indiv idually.
Therefore, each pair of speakers can be driven
with a n optimized frequency.
The frequency divider can adjust t he HPF (high
pass filter) or LPF (low pass filter) of each band,
and the slope (the speed of the filter to t he h igh
point or low point).
Should be adjusted according to the
reproduction characterist ics of the speaker.
Depending on the speakers, it may not be
necessary to use a passive network. If you are
not sure about t his, please consult an
authorized Alpine dealer.
