    Highlights
  • Four-layer circuit board optimized for mixed signals
  • Designed specifically for the ESS Sabre PRO Series DAC chips (ES9028/38)
  • Pre-configured for 2-channel (stereo) operation
  • High-precision, ultra-low-phase noise clock and integrated reclocking
  • Optional external master clock connections
  • Five independent supply inputs for digital and analog stages
  • Direct DSD, DoP, I2S and S/PDIF inputs supporting up to 32-bit/384kHz and DSD512
  • Switchable stereo S/PDIF input, or 2 channels of PCM/DoP/DSD
  • Accepts both consumer-level and TTL-level S/PDIF input
  • 2-Channel (stereo) outputs can be used in current-output or voltage-output mode (depends on output stage used)
  • U.FL connections for digital inputs and external Master Clock
  • Built in digital volume control using the including volume pot
