User manual RANE AC 23

[. . . ] 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 Delay circuits appear on the Low (& Mid when used in 3-way mode) 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 also possible with an internal modification. See the RaneNote Linkwitz-RileyCrossovers: A Primer, available from our website.

When all drivers in stacks are equal and acoustic differences are not critical, delays are not required, and simplicity of use is important, we recommend the Rane SAC 22 or SAC 23 Crossover. Architectural Specifications The active crossover shall contain 4th-order Linkwitz-Riley filters. Provisions shall exist to correct for driver misalignment by means of adding time delay to the low frequency outputs. The 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 active balanced terminated with XLR connectors. The active crossover shall afford an input level range of off to +6 dB. The output level controls shall afford a level range of from off to +12 dB with muting capability on the low frequency outputs. The crossover shall supply two independent channels. The unit shall be exempt from agency safety requirements and powered from a UL listed, CSA certified remote power supply (120 VAC) or CE approved (230 VAC) via a rear panel input modular plug. [. . . ] The unit shall be exempt from agency safety requirements and powered from a UL listed, CSA certified remote power supply (120 VAC) or CE approved (230 VAC) via a rear panel input modular plug. The unit shall be constructed entirely from coldrolled steel, and mount into a standard 1U EIA rack. The unit shall be a Rane Corporation AC 23 Active Crossover.
