DRC is Dynamic Range Compression. The range mixer defines the range it
compresses to, so if DRC is enabled with an empty range you mostly hear
nothing.
Monitor is the level at which input is forwarded to output directly
(watch out for the feedback loop via the built-in microphone!).
I've wondered myself what 'PCM 1' is, anyone?
