General Description
The Rane AC 22S Active Crossover is configurable as Stereo 2-Way or Mono 3-Way.It employs state-variable 4th-order Linkwitz-Riley filter alignments tominimize phase difficulties in the critical crossover region. Simply put, aLinkwitz-Riley alignment is two cascaded 2nd-order Butterworth filtersexhibiting identical phase characteristics on their Low-pass and High-passOutputs. This guarantees in-phase outputs at all frequencies, mandatory forproper acoustic summing of common signals from adjacent drivers in thecrossover region. An added benefit of this topology is steep 24 dB per octaverolloff slopes. A slope of this magnitude guarantees drivers designed toproduce a specific range of frequencies, and no more, will not be driven pasttheir limits, thereby minimizing distortion and driver fatigue.

To further guaranteethe transparent operation of the AC 22S, adjustable time delay circuits appearon the Low (and Mid when used in 3-Way mode) outputs of each channel tocompensate for any physical misalignment of the drivers. Time correctionensures the mechanical phase alignment of adjacent drivers will be acousticallycorrect, thus maintaining the integrity of the electrical phase alignment ofthe crossover's filters. CD horn equalization is possible with an internalmodification. A Mono Subwoofer switch provides the option to sum both LowOutputs in Stereo 2-Way mode.
