Protea 3 Input, 6 Output Digital Speaker Processor

The 3.6SP is a three input/six output digital signal processor capable of precise control of a broad range of audio functions. The front panel interface allows quick access to all control parameters by offering dedicated function buttons, eliminating the need for hidden sub-menus. A backlit 2 x 20 character LCD displays channel and function settings. Dedicated buttons provide access to all audio functions and system tools. For even faster set-ups and stronger visualization of Input/Output routing, EQ, and Filter curves, two USB (one on the front and one on the rear panel) and RS-232 port is provided for use with Ashly's control software (Protea Software Suite) and a PC. A six foot USB-A to USB-B cable is provided. Advantages of using the software include greater preset capacity, and a very intuitive visual representation of the audio routing and control process.

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.
