RANE AC 23B Active Crossover (1U) Stereo 2- or 3-Way, or Mono 4- or 5-Way

The Rane AC 23 and AC 23B Active Crossovers can be configured as Stereo 2- or 3-Way, or Mono 4- or 5-Way. The model AC 23 connects with 1/4" TRS balanced/unbalanced Inputs and 1/4" TS unbalanced Outputs. The AC 23B uses XLR connectors with active balanced Inputs and Outputs.

These crossovers employ 4th-order Linkwitz-Riley filter alignments to minimize phase difficulties in the critical crossover region. Simply put, a Linkwitz-Riley alignment is two cascaded 2nd-order Butterworth filters exhibiting identical phase characteristics on their Low-pass and High-pass outputs. This characteristic guarantees in-phase outputs at all frequencies. In-phase outputs are 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 rolloff slopes. A slope of this magnitude guarantees drivers designed to produce a specific range of frequencies, and no more, will not be driven past their limits, thereby minimizing distortion and driver fatigue.

To further guarantee the transparent operation, adjustable time Delay circuits appear on the Low and Mid 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. Time Delay can also be internally transplanted to the Mid and High Outputs if desired.
