Architectural Specifications
e active crossover shall contain 4th-order Linkwitz-Riley
filters. Provisions shall exist to correct for driver misalignment by
adding time delay to the low and mid frequency outputs.
e crossover frequency shall be controlled by a continuously
variable control with 41 detents to allow mechanical reference of
crossover setting.
Signal inputs and outputs shall be of active balanced design
terminated with XLR connectors. RFI, infrasonic, and ultrasonic
filters shall be built-in.
e active crossover shall afford an input level range of Off
to +6 dB. e output level controls shall afford a level range of
from Off to +12 dB with muting capability on the low and mid
frequency outputs. e crossover shall supply two independent
channels.
e unit shall be capable of operation by means of its own
built-in universal power supply operating at 100-240 VAC and
meet CE requirements. e unit shall be UL and cUL listed. e
unit shall be entirely constructed from cold-rolled steel.
e unit shall be a Rane Corporation AC 23S Active Crossover.
Choosing the Right Configuration:
Mono, Dual Mono, or Stereo?
Very few systems indeed will utilize a two channel crossover
for the purpose of true stereo imaging. Discrete stereo channels
which are run from the mixing board are usually used for
panning effects and/or for separate equalization of left and
right speaker stacks. Different sides of the room often require
significantly different equalization due to varying room
acoustics, dimensions, positioning of speaker stacks near walls,
curtains and the like.
Even though you may not plan to use stereo equalization
or panning effects, it is recommended that your system utilize
discrete crossover channels for each stack of speakers to ensure
flexibility and control for consistent, optimum sound quality.
For example, if you plan to run a multi-stack system mono
three-way, use the AC 23S rather than the AC 22S for separate
control over each set of speakers—especially since phase
alignment may differ with each stack requiring separate time
delay adjustments. Even with only a single system equalizer, the
AC 23S can deliver the extra independent control which can
make a difference in sound throughout the listening area. If all
drivers are built into a single cabinet, or you are running bi-
amped monitors, then the AC 22B is the one for you.
