Rane AC 22S Active Crossover


The Rane AC 22B Active Crossover is configurable as Stereo 2-Way or Mono 3-Way. It employs state-variable 4th-order Linkwitz-Riley filter alignments to minimize phase difficulties in the critical crossover region.

The Rane AC 22S features a Linkwitz-Riley alignment is two cascaded 2nd-order Butterworth filters exhibiting identical phase characteristics on their Low-pass and High-pass Outputs. This guarantees in-phase outputs at all frequencies, mandatory for proper acoustic summing of common signals from adjacent drivers in the crossover region. An added benefit of this topology is steep 24 dB per octave roll off slopes.

To guarantee the transparent operation of the Rane AC 22S, adjustable time delay circuits appear on the Low (and Mid when used in 3-Way mode) outputs of each channel to compensate for any physical misalignment of the drivers. Time correction ensures the mechanical phase alignment of adjacent drivers will be acoustically correct, thus maintaining the integrity of the electrical phase alignment of the crossover's filters. CD horn equalization is possible with an internal modification. A Mono Subwoofer switch provides the option to sum both Low Outputs in Stereo 2-Way mode.
