By Gary Zandstra • October 25, 2018 Image courtesy of Wilfried Pohnke Do you replace production/system equipment based on it being worn out or for new features and functionality? When we get a new system or new piece of gear, often the last thing on our minds is repairs or the life cycle of the system. In my view, churches are getting better at understanding professional A/V systems. I find that in general the market is more aware of the cost versus the expectation of the system, along with the willingness to spend the dollars to get it right (or at least as right as they can afford). I’m grateful for the improvement. However an area where I see little or no improvement is in operation, maintenance and lifecycle replacement expectations. This article is provided by Gary Zandstra.com. It’s not uncommon for a church to spend hundreds of thousands of dollars on a great sound system and then never think about who is going to operate it, and just as importantly, who is going to be responsible for maintaining it. In fact, too often I see churches balk when one of the sound techs asks for a few hundred dollars to attend a tech training conference. Another factor is the short(er) lifecycle of today’s equipment I don’t mean that stuff fails sooner; it’s more that technology keeps surpassing itself. The church that I serve has been in a new sanctuary for only seven years. When the technical systems were designed and installed, digital consoles were in the early (and generally pricey) stage. HD video was being discussed but not widely adopted. Line arrays for permanent installations had just recently come into fashion. All that said, my church has a great-sounding left-center-right main loudspeaker system, a premium 56-channel console, and a 12 x 16 rear-projection system that works well. Even so, we’ve started discussions on replacing some of our equipment. (Well, actually “repurposing” is more accurate, because the current stuff will be utilized elsewhere in the church.) Part of the push to replace is based on age. The console is starting to have some minor issues (although nothing yet that can’t easily be repaired). But in reality, the big push is based on changes in both technology and expectations. We’ve started hosting concerts in the space, and the main system has a hard time getting over 100 dBA. So with technology moving so quickly, what should you expect when purchasing a new system? 1) Don’t expect it to perform at its best without having qualified and trained personnel operating it. 2) Do expect it deteriorate without regular maintenance. I suggest having systems checked annually by a professional contractor, even if there are not any apparent problems. 3) Don’t expect it to last forever. Be realistic about the life expectancy of the equipment, and more importantly, recognize that the technology in most cases will become obsolete before it fails. I’ve read that the average life expectancy of an A/V system is as little as three to five years (especially when you’re talking about video projectors). 4) Do expect to need to educate the leadership at your church as to how and why the technology needs to be updated. Actually, this is an activity that needs to happen on a consistent basis – no one likes to be surprised with a big ticket purchase that was not anticipated. How can you go about it? 1) Upgrade as you go, a piece or two at a time. This can be a great way to keep a system current. As new, beneficial technology becomes available, cycle out the older stuff. For example, the system is working fine and sounds good, but the mixing console is coming up on 10 years old. So it could be replaced with a newer model, and at the same time, you can be planning similar transitions for loudspeakers, amplifiers and so on. The main problem I see with this approach is that if the leader of the technical area is not the same person for a number of years, the upgrade process can suffer from lack of consistency. 2) Take the “big leap” and do an overhaul every 7 to 10 years. I’m currently working with a large church on a significant upgrade that has taken almost five years to come to fruition. Over that time span, the design has changed and the cost estimate has increased, but what has stayed consistent is the accumulation of money to do the project. The key thing in making a significant upgrade happen is to have a vision, backed by a concrete plan to have the money available to do it. By outlining the project at the outset and then accruing a bite-sized chunk of the cost, year after year, the church has been able to do steadily accomplish its vision without having to do the typical fund raising, committee meetings and deacon approval. To me, both ways work – it’s just very important that the discussion gets started early and that people are onboard in their commitment to technical system excellence.
