How Churches Save Money with Independent AVL Design

Tom Thelen | Worship | October 1st, 2009 | Leave A Comment

image a church sanctuary digital sound board from church audio-visual consultantsIn this economy, everyone is trying to cut costs and save money, and churches are no exception. With most church budgets relying 100% on church member donations, there is a heightened sense of concern amongst church boards to spend the money wisely. So when churches hear about an AVL company that will design a new Audio, Video, and Lighting system for “FREE!” many of them jump at the chance. But what does a “free” AVL design package really get you anyway? (more)

Why Techies Buy Audio-Video Gear Online

Tim Hamilton | Worship | July 23rd, 2009 | 2 Comments

My church recently decided to upgrade from our old analog mixing board to a brand new digital mixing console. The interesting part of this process was that they did not buy it through a local AV contractor. They purchased the sound board online through a company that specializes in phone and internet box sales. This got me thinking about the trend over the past few years in which more and more Audio Visual end-users purchase equipment from online sources instead of the local dealer or shop. Is this a good thing or a bad thing? And why is this becoming the norm? (more)

White Space Update for Wireless Microphones

Perhaps the toughest and most critical element of designing AVL systems for auditoriums is proper coordination with all the other teams. As audio-visual and theatrical lighting designers, we find ourselves being selected to join teams all throughout the process, from design development to construction administration to commissioning, and this can create a lot of challenges for the AVL system integration.

Decision 2008 – White Space Disaster for Wireless Mics

Tim Hamilton | Worship | November 13th, 2008 | 1 Comment

Last Tuesday, while many of us were casting our votes in the presidential election, the Federal Communications Commission (FCC) was making a landmark decision of its own. On their private ballot was a proposal to open the so-called “TV White Spaces” of the frequency spectrum for expanded use. And on November 4th, the proposal passed. Sounds all fine and good, right? Well, maybe not. If the FCC’s current plan goes through, it will lead to a crossroads for the wireless microphone industry and for AV designers. (more)
