Hand-assembled in Kent County, Chord DAVE is based on proprietary FPGA technology (Field Programmable Gate Array – programmable gate arrays). The design is based on the new Spartan 6 Field Programmable Gate Array chip version LX75.
The output section of the device is completely discrete, guaranteeing a reference noise reduction. As a result, the technical characteristics of the Chord Hugo TT2 are described as fabulous – distortion does not exceed 0.00008%, channel separation reaches 138 dB, and the dynamic range exceeds 127 dB.
A compact DAC with a unique digital stuffing on programmable FPGA arrays, the entire digital path is implemented using the algorithms of Rob Watts, chief digital Engineer at Chord Electronics.
The engine of the Chord Hugo TT2 is a Xilinx Artix 7 Field Programmable Gate Array (FPGA) custom coded by Rob Watts – it consists of 86 cores, each running in parallel at 208 MHz, and the overall system design is now based on ten elements. As result, the time reconstruction filter, 16FS WTA 1, operates with 16x oversampling and an accuracy of 98,304 weighting coefficients (taps). Disclaimer - Hugo 2 operated with 49,152 taps.
