I know you are a lot more knowledgeable than me about pro audio. Ultimately the music director of our church will make the decision on what board would be the wisest investment for the church with all things being considered. The church will then put it to a vote.
I told him about this thread and invited him to take a look at the discussion. I know that he preferred 32 channels to 24 when we were discussing the prosonus studio/live unit.
I believe he will be well informed after reading this discussion and your behringer x32 thread.
Thanks man.
