Professional Usb Digital Audio Signal Processing 4 Input 8 Output Dsp Sound Processor 
 
Introduction
 
The 4.8SP has four inputs and eight outputs. The front panel interface allows quick access to all control parameters by offering dedicated function buttons, eliminating the need for hidden sub-menus. For even faster set-ups and stronger visualization of Input/Output routing, EQ, and Filter curves, a USB port is provided for use with Protea NE Software. Full control by third party controllers is also available via
RS-232.
 
 
Features 
The Protea 4.8SP  utilize state of the art DSP technologies, beginning with 24 bit, 48kHz delta-sigma A/D converters with 128x oversampling. Digital processing includes Gain, Parametric EQ, Shelving Filters, Time Delay, Crossover Functions, Compression, Limiting, and Matrix Routing, all taking place in twin 120MHz Motorola DSP56362 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.
