The DAC system is based on the same PCM1792 chip, but is entirely redesigned, and interfaced through digital isolators to I2S lines on ST/STX board. Double regulation levels using TPS and ADM7151 ultra low noise regulators on DAC board. The fully differential (OPA1632) I/V and final buffer are also powered by TPS ultra low regulators dedicated to every opamp chip on board. Independent PSU using R core transformer, with AC main filter. This DAC system is completely electrical isolated from the rest of the computer.
The stock clock oscillators on original ST/STX board are replaced by NDK/Connor-Winfield ones, which are powered from battery. The battery provide power for more than 40 hours continuous functioning (charging while the system is powered off). The clock board is damping mounted to completely prevent any mechanical vibrations from the rest of the host computer. Power up/down management included.
Balanced outputs (XLR) as standard (right and improved AC coupling approach), with RCA are also available if necessary.
The sound card it still be fully functional in its original design. The new added DAC system it works in parallel with the original one.
