DSD to PCM filter?

A) What does this do, and how might I use it?
B) Why is there no Help or explanation of this setting?
C) What is the “right” setting for a PS Audio DirectStream DAC?

@Richard_Zehr you don’t need to bother about this settings unless you really want to convert the incoming DSD stream to PCM while sending it to P S Audio dac.

Out of the box Roon will by default send to bridge DSD stream (uptill 64) in its native format without changing anything and Brdige II can handle the same. In the DAC display you’ll see that it is showing DOP and 64.
