i want to use the Beocreate Boards to activate a pair of 4-way Speakers (Visaton Atlas Compact). All worked fine if I use old Setup (passive Crossover and Beocreate configured on Fullrange Speaker). Next step would be to remove passive Crossover, connect each Chassis to one of the four Amps of the Beocreate Board and use Sigma Studio to create a digital Crossover. But in Tools Section there is only 2-way and 3-way Crossover for ADAU 1451. Is there any way to add a 4-way Crossover?
