ok so send the snare to a new fx channel and load an eq and a compressor into it (sequential inserts)
use the eq to add some oomph around 200Hz (you''l need to tweak this value to taste) boost +3 - +6db (you'll need to tweak to taste as well)
now with the compressor threshold around -40dBFS, fast attack, moderate release, moderate knee, compression ratio 10:1, makeup gain the same as the eq
Use the fx channel fader to colour the snare sound
the above is parallel compression, sometimes called New York compression but should in fact be called New Zealand compression as the first guy known to do it (by Bob Katz) was a New Zealander
