General Description
The Rane AC 23B 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. The AC 23B uses
XLR connectors with active balanced Inputs and Outputs.
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 of the
AC 23B, 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 modifica-
tion. See the manual for details.

information.
