If, for any reason, the Satellite Output on
the subwoofer is not going to be used to
feed the
variant 25A
units, then it is
recommended to make use of an external
processor to high pass filter the signal fed
into the
variant 25A
unit at 138 Hz, and add
the necessary time delay to match the
phase at the cut off frequency.
When
variant 25A
units are used in combination
with
variant 18A
subwoofers it is recommended to
plug the mixer into the
variant 18A's
input and then
to connect the
variant 18A
138Hz high pass filtered
output to the
variant 25A
input.
The ratio between
variant 25A
and
variant 18A
units that DAS Audio recommends to achieve a
correct balance is 4:1 (As it depends on the kind
of music and the application, it is subject to
changes). A level knob can be found on the
variant
18A
amplifier panel which allows for decreasing the
subwoofer level when less than four
variant 25A
units are to be used, allowing to correct the
balance between Mid-High and Low frequencies.
