The Bluefin HDSP was a revolution in DSP processing card for broadcast sound mixing consoles. It was revolutionary because, for first time it was possible to have all DSP for entire console on a single card. For multichannel surround mixing Bluefin2 is most efficient technology available today. With a colossal 1020 channel processing paths on one DSP card, Bluefin2 is most powerful DSP technology for audio processing currently available with a 432% increase in processing power in just 1% of physical space when compared to Calrec's non-FPGA based DSP processing system. Bluefin2 also provides all these facilities with no restrictions on DSP structure - all are available, all time.
