Product Information
PROTEA 3.24CL DIGITAL CROSSOVER/SYSTEM PROCESSOR
Three inputs and six outputs coupled with an incred- ibly easy front panel user interface, the Ashly Protea System II 3.24CL Digital Crossover/System Processor has all the audio processing tools you need for pre- cise crossover, system sound control and superior sonic quality.
Each input allows you to control gain, delay and six filters (each of them your choice of parametric, low or high shelf). Each output permits you to set your crossover frequencies and may be assigned to any one or a combination of inputs. Additionally, you can program four filters (each of them your choice of parametric, low or high shelf), control delay for time delay adjustments, adjust output gain, reverse polar- ity and control a compressor/limiter for speaker pro- tection. All this in one rack space with XLR input and output connections.
