Featuring Linkwitz-Riley filters.
The Rane AC 23S Active Crossover can be configured as Stereo 2- or 3-way, or Mono 4- or 5-way. Connects with XLR active I/O. Employs 4th-order Linkwitz-Riley filter alignments to minimize phase difficulties. Adjustable time delay circuits appear on the Low and Mid outputs of each channel to compensate for any physical misalignment of the drivers.
