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.
