I am designing several churches.

Can you give me a generic spec for the following wiring? [I don't
mean a specific brand, just a designation, like "CAT-5" and "RJ-45"
for network wiring, etc]

From Microphone jacks at pulpit to sound board
cable: 2-conductor shielded audio cable
connector: XLR or TRS as appropriate

box recessed into pulpit [brand name/# ?]
From Sound Board to amplifier
cable: 2-conductor shielded audio cable
connector: XLR or TRS as appropriate

From Amplifier to Speaker Jack
cable: 12-16 gauge low voltage
connector: 1/4" mono phone or SpeakOn as appropriate

From Video Projector to PC at sound board
cable
connector

Depends on the input video projector, but if it has a 15 pin RGB input, then
one uses RGB extension cables such as are used with KVM switches.
