A Resync Delay setting of 1000ms is recommended to allow NADAC D to properly reconfigure when changing from PCM to DSD.

If using a USB connection, the source device must support the UAC 2.0 protocol (USB Audio Class 2.0). The NADAC D hardware supports up to PCM 384kHz/32bits and DSD512.

If using Coaxial, Toslink or AES connection, the source device port must comply with the S/PDIF protocol, and should support up to 192kHz/24bits or DoP64.
