The Protea 3.6SP utilizes state of the art DSP technologies, beginning with 24 bit, 48kHz delta-sigma A/D converters with 128x oversampling. Digital processing includes Gain, Polarity Invert, Parametric EQ, Shelving Filters, Time Delay, Crossover Functions, Compression, Limiting, and Signal Routing, all taking place in twin 120MHz high performance DSP processors. D/A conversion uses 24 bit delta-sigma converters with 128x oversampling. All inputs and outputs are precision balanced and RF protected using XLR connectors.
Each input allows you to control gain, delay and six filters (each of them your choice of parametric, low or high shelf). In addition to setting crossover frequencies, each output may be assigned to any one or a combination of inputs, allows you to program four parametric, low or high shelf filters, delay for time delay adjustments, output gain, reverse polarity and a compressor/limiter for speaker protection. All this in one rack space with XLR input and output connections.
The 3.6SP will store up to 30 total presets. A preset file takes a “snapshot” of all current settings and stores complete control data for all channels and all audio functions. The Protea 3.6SP is similar to the older Ashly Protea 3.24CL/CL-d. An existing preset file from the older *.pcc format can be loaded onto the new 3.6SP unit.
In all, the Protea 3.6SP is a powerful, easy to use processor for use in live sound or fixed installation applications combining precise audio processing and superior sound.
