Rivo has 3 kind of audio outputs onboard.
SPDIF (up to 192KHz/24bit PCM audio)
AES/EBU (up to 192KHz/24bit PCM audio)
USB DAC 5V low-noise filtered (up to 768KHz/32bit PCM audio)
SPDIF and AES EBU filtering and isolation have been meticulously designed by employing multiple 1:1 OFC copper grain-oriented transformers, which guarantee the galvanic isolation of these digital outputs
