The AC 24 from Rane is a dual mono/stereo 4-way crossover that combines conventional analog controls with DSP signal processing. The unit is ideal for those who want the features and accuracy of DSP, but prefer not to use a PC for control. Each knob has a dedicated function.
The crossover combines Rane's exclusive phase compensated, 4-way Linkwitz-Riley-Plus crossover filters with independent time delay and limiting for each output. 0 to 10 mSec of time delay can be added to each of the low, mid, hi-mid and high frequency outputs. Once settings are fixed, an included security cover guards all controls from accidental change.
