ACX2210 X/O

The Prosonar ACX2210 is the evolution of a common analogue active crossover, with improved ease of use and better level of control. Specifically targeting stereo sound reinforcement, the ACX2210 avoids unnecessary duplication of settings for both stereo channels by common controls for both channels. Precise level meters for all inputs and outputs, and adjustable peak limiters for all outputs protect speakers from unhealthy signal levels, so does the switchable input high pass filter. If the system setup allows subwoofers to be located together, or only a single subwoofer is used, the Low output can be switched to mono operation.
