The World Premiere of Formula xHD will take place this weekend at RMAF – Room 4009 by Mark Sossa of Well Pleased Audio.
The Formula xHD features the following upgrades and modifications as compared to the Formula DAC:
– New firmware release 3.0 for the main FPGA (DAC) with optimization of the code
– New USB board with hybrid architecture cod. A108
Features
• Proprietary hybrid 2-stage XMOS xCore XE216 + FPGA
• Fully-floating (isolated) USB decoding and clock generation by FPGA with proprietary code
• High quality, long life, low noise parts and modular design that distinguish aqua – acoustic quality equipment
• Sample rate in “Bit Perfect” up to 768 kHz PCM and quad rate DSD (DSD256)
• Latest version of customized XMOS X Core Driver on Windows OS (W7, W10)
• Native X Core Audio on Mac OS (Bit Perfect)
• USB Audio 2.0 operation on Linux (Bit Perfect)
This update has required significant optimization of code for the main FPGA of R2R ladder DAC which has improved sound quality.
The new hybrid USB XMOS xCore 200 (dual core) + FPGA circuitry enables the high-resolution file playback up to 768kHz PCM and up to DSD256 (Quad DSD)
