The AC 24 stereo 4-way Crossover combines conventional analog controls and DSP signal processing. The AC 24 is ideal for those who want the features and accuracy of DSP, but prefer not to use a PC for control. One knob = one function — no confusion. This approach allows a full-featured, high performance product that doesn’t break the bank. The AC 24 is a truly affordable crossover that features the very best technology, with exactly the right features.
The AC 24 combines Rane’s exclusive phase compensated, 4-way Linkwitz-Riley-Plus crossover filters with independent time delay and limiting for each output. Once settings are made, an included security cover guards all controls. With these tools, it is possible to realize a well-protected sound system that exhibits unsurpassed clarity and accuracy.
See the RaneNote Linkwitz-Riley Crossovers at the Rane website for background information.
