Ashly 3 24CL Digital Crossover/System Processor
Ashly-3-24CL
Ashly 3.24CL Protea System II Digital Processor The Protea 3.24CL was developed for smaller audio systems requiring fewer inputs and outputs without sacrificing sonic quality. Three inputs and six outputs coupled with an incredibly 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 precise crossover, system control and superior sound. 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 polarity and control a compressor/limiter for speaker protection. All this in one rack space with XLR input and output connections.
