Church Tech is not my particular thing but I’m sure there are plenty of resources & contacts out there. If you have anything that would be worth adding in here please don’t hesitate to drop me a line in the Contact Us page.
I do have a buddy over in the States, Tim Adams, who is more than adept and runs a Google Plus page dedicated to Adventist Church Tech.
This community exists as an open forum for active discussion, troubleshooting, support, and prayer for those individuals who volunteer or work with audio, video, lighting, and/or projection equipment at their Seventh-day Adventist Church.
You can find his page here > [Link]
