[. . . ] System Applications AC One Audio Controller--Patented Engineering for Optimized Performance The AC One Audio Controller includes a newly designed crossover function (patent pending) that improves SPL around the crossover frequency. [. . . ] Of course, adding a centrally located subwoofer can also improve the sound quality. The AC One Audio Controller was designed for use in high-performance installations that employ active 2-way systems plus subwoofers. Such applications usually incorporate professional linear power amplifiers like the EV P1200, P2000, P3000, Force, Eliminator or the new P1201 and P1202. When a processor-controlled power amplifier like the EV P1250 is used, the processor section is simply switched off. The user does not need to know any complex detail about crossover functions and equalization. All controls for matching the sound to different acoustic conditions and loudspeakers are located on the front panel. Difficult tasks--for instance, electronic signal routing and settings---are automatically carried out inside the controller. The PowerMax 12 crossover function makes optimal use of amplifier output power and loudspeaker transmission capacities.
