I know this post is super old, but thought I'd throw in my 2 cents.
33609s are really cool compressors, but I've found one singular use I like them for: Drum Bus or Drum Parallel
Settings I use:
Limit Section Bypassed / Not Engaged
Compressor
- Threshold : usually full blast
- Recovery : by tempo 100ms for fast stuff, 400ms for most stuff
- Gain : just enough to compensate for reduction
- Ratio : 2:1 or 1.5:1
- Attack : fast generally, slow sometimes.
For parallel I'll do fast attack and then get 8-12 db of reduction
For main drum bus I'll do 1-3db of reduction on the snare hits.
I know some people who use it on their master bus, but I never got it to work how I wanted.
