I'm happy that technology is being used as well, but when it comes to budget money - I'm a stickler. It's the Church that has decided on the standard meetinghouse plan, it is the church that has created the policy around what 'technology' equipment that a stake can use their own budget for, etc... If the Church wanted to be able to support that many microphones, they should provide that many, or have the FM group own that many to borrow along with a mixer.
In my last stake we had an FM that did just that, he had 4 mics that could be borrowed, and he asked me to come help him understand how to set them up and work with them, etc... We went to a meetinghouse and he quickly figured out his own dilemma (I purposely played along like I didn't know the xlr input problem he was going to encounter). I went to my car, got my audio mixer and showed him how they could all be setup. So he purchased a simple mixer and we were in business.
This is also where I came to understand the problem. He (FM) asked me to help him setup for a Mission President seminar held in our area. Several GA's were there and they traveled with a 'Technology Kit' - it had an appletv, projector, wireless AP, and a mixer to get the appletv sound into the hotel conference room sound system, though we didn't use it. The conference room had the ability to use 8 microphones and included them as part of the conference room fees (though it was a per-item price) so the FM was trying to use his microphones as well. Anyway... it seems that at times they do travel with a technology kit, but only if they don't use a local church building for their meetings.
