>Do you notice any difference in quality with the mini-xlr's or is the big advantage that they do lock?
As far as the sound quality, I think it's the use of the power modules themselves, I run an AT8532 module for each mic and each module runs on a 9V battery. I do love that they lock, and the output for the modules is the larger xlr, so they also lock, the only non-locking connection I have is the 1/8" mini going into the recorder.
I mainly record loud rock/classic rock shows and running the modules also allows some pretty high SPL, I've run literally right under huge stacks at Rush and even front row in front of huge stacks for the Scorpions and got great results. They also work nicely in a variety of settings, from arenas and sheds to smaller theaters and even outdoor open air fair style gigs.
>I may have to pick up the subs and give them a whirl... With the sub elements do you find you need to roll off the bass any like >you'd have to with the omni elements?
I've pretty much run the subs, cards and omni's with flat setting (no bass roll-off) and have never really had any issues, maybe some have had a slight cut in post. The subs are similar to the regular cards, but give you more of an omni feel with more room space feel and some added punch clarity.
Alot of this has to do with how the sound person is running the sound and your location in the venue and how loud of a SPL is coming from the PA, but as far as all-around capture of sound I really like how the power modules work with the 933's.
If you have access to DIME you can search my username there and find a list of some shows I have taped, pretty much all of those are the 933's running with the power modules and include arena, shed and HOB style shows.
