SOFTWARE DEFINED ARCHITECTURE & FPGA TECHNOLOGY
Wavelight DAC employs the latest Xilinx 7-series FPGA which allows us to assemble the functions of a custom high performance R2R processor. The Wavelight’s digital processing capabilities are built with complex VHDL coding and state of the art FPGA hardware. The architecture is described, in fact, by a piece of software.
When upgrading the Wavelight with new firmware, you actually change its hardware. This system allows great flexibility, obsolescence protection and lets us improve the sound of your dac by changing its internal architecture, add new, cool features, or improve the existing ones. Each digital block is custom built under the Rockna Audio high-performance standard.
