There just seem to be so many people on here at present who seem to be struggling with little know-how and a basic PA system to operate, I am starting to wonder why we seem to have so little interest (world-wide) in helping to educate people in this noble but dedicated/demanding form of service to Church life, thank God for Forums like this!
One very similar post on this forum has some of your answers already see
http://forums.prosoundweb.com/index.php/topic,1971.0.html I think I have a slightly out dated document written by a brit Church PA Tech, that I could email to you, if you would like it as a sample of suitable contents.
However as there is potentially so many areas of technology, electronics, instrumental and A/V needs which will always develop and evolve in a Church, it is very tricky to write more than a basic quick set-up and guide for your helpers with perhaps a couple of stage layout pictures and interconnect diagram; Regular hands on experience is almost always the the best best way to get helpers familiar with a system. Treasure the guys who take extra interest and may be prepared to spend extra time in band practices (A great time to learn and experiment, with due consideration to your worship teams need to rehearse un-hindered). Additionally any one who is interested enough to ask sound related questions, get the Church to buy them some reading material or read online information like this; Feed the thirst for knowledge and reap the rewards!
There are so many variables to Sound and helpers with varying levels of knowledge that you will be trying to write the equivalent of a document on how to build (say) a car with info about the various uses it may have I.E. should it have Wirless mics, have monitors, Specific DI settings, How to identify and utalize Phantom power equipment, Recording settings & options, And then you could also the mounting options and merits of all of the available accessories you could own for it, A Long Complex Document (Possibly).
Personally I believe that if Churches want to evolve and improve their Worship and media experience's, they ought to nurture and encourage those who potentially may have a lot to give with some support.
I have to close and say that I appreciate that you Jared are trying to improve things with your technology, but a large part of it is the bigger picture of trying to nurture an interest with the Church leaders, Musicians and Worshippers, Some Churches see the PA system as a scary problem, others learn to use it as a creative and wonderful tool, and if it is a blessing to have a system then invest wisely in the people who will give their valuable time to operate it, i.e. get them them cared for as much as they appear to care for a senior worship leader, as mentioned to me recently: The PA system is probably the most complex and largest (or potentially destructive) part of a worship band & service enviroment.
PS. Keeping a library or PDF copies of any user manuals for learning reference is always good for interested readers, You-tube too can have some good clips of instructional information.
Just my Thoughts!
