    titleNote on Volume Leveling and Crossfade options

    Both Crossfade and Volume Leveling options in the Zone Settings page enables a sampling rate conversion for DSD files, which will prevent NADAC to run in DSD native mode, the conversion will force the device to run in DXD mode. Disable the Volume Leveling and leave the Crossfade option to 0 seconds if you don't want this conversion.

    titleDSP ENGINE

    Please use Roon DSP Engine features with caution, it can be very demanding resources wise, and therefore can cause drops for multichannels / high sampling rate playback !
