PA systems and discotheque sound systems. The SE100 will be connected behind
the master output of the audio mixer. You can also use the subwoofer output to
drive an extra subwoofer amplifier which results in an additional power punch!
 SE100 can be inserted in the monitor send of a PA mixer to enhance the sound
quality of monitor speakers.
 SE100 can also be used between a tape deck and mixing console to enhance the
sound of the tape deck.
 SE100 can be connected between the record output of a mixing console and a tape
deck to enhance the sound that will be recorded.
