The HoRNet 3XOver is a very peculiar plugin since it's half a DJ eq, half a three band crossover with selectable slope and output for each band.
At its core there is a system of three filters, a low-pass, for the low frequencies, a band-pass for the mid frequencies and a high-pass for the high frequencies.
Each of the filters has a selectable slope of 24dB/Octave or48dB/Octave, a freely adjustable cutoff frequency point,gain control, and a ON/OFF switch to kill that frequency band.
The 3XOver provides four different stereo outputs, a Master (identified by an "M" on the output selectors) and three auxiliary outputs (identified by the numbers "1","2" and "3" on the output selectors).
You can assign every band to any of the outputs of the plugin, this allows for great flexibility, from the basic three band DJ equalizer to a multi output crossover that can be used to build custom multiband compressors for example.
