Crossovers affect audio signals by separating frequencies, generally by implementing Low or High Pass Filters. In Vocia, the electronic filters available are Butterworth, Bessel and Linkwitz-Riley types. Two Crossover filters are available per channel in Vocia audio output devices and amplifiers. Any changes made to the filter settings are represented by colored lines that appear in the Crossover Filters window. In addition to simply adding numeric values in the applicable Frequency textboxes, the colored lines are able to be clicked and dragged to create frequency cutoff settings. Configuration of Crossovers is performed via the functions listed below:
