Crossover, EQ, delay and limiter functions for smaller systems.

The Ashley Protea 3.24CL was developed for smaller audio systems requiring fewer inputs and outputs without sacrificing sonic quality. The Protea 3.24CL processor has 3 inputs and 3 outputs coupled with an incredibly easy user interface on the front panel with all the audio processing tools you need for precise crossover, system control and superior sound.

Each input allows you to control gain, delay and 6 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 4 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.
