General Description
e Rane AC 23S Active Crossover can be configured as a stereo
2- or 3-way, or a mono 4- or 5-way. It employs 4th-order Linkwitz-Riley filter alignments to minimize phase difficulties in the
critical crossover region. e AC 23S uses XLR connectors with
active balanced Inputs and Outputs.
Simply put, a Linkwitz-Riley alignment is two cascaded 2ndorder Butterworth filters exhibiting identical phase characteristics on their low-pass and high-pass outputs. is 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 of the
AC 23S, adjustable Delay circuits appear on the Low & 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.
In 2- or 3-way stereo mode, the low outputs may be mono'ed
by moving an internal jumper. Constant directivity (CD) horn
equalization is possible with an internal modification. See the
manual for details.
