17 seconds to better audio
Listen to for 17 seconds to hear the difference that 17% can make.
Problem: The main worship facility at South Delta Baptist Church of Delta, British Columbia seats approximately 1600 people with both main floor and in the upper balcony. Due to a 4 second reverb/decay time, a large percentage of the congregation was challenged in hearing the message due to a lack of vocal intelligibility - caused by excessive reverberation and echo.
Solution: Primacoustic Broadway panels were placed on only 17% of the wall surface and spread evenly throughout the sanctuary. Since the style of worship incorporates amplified instruments, careful attention was paid to the stage area to control reflections from vocal monitors, guitar amplifiers and drums.
As a result, reverberation was decreased from 4 seconds to just over 1 second, greatly improving intelligibility and enhancing the worship experience for everyone.

Doing it right.
A few months ago, we got a call from a pastor about the sound quality in the main worship space. He talked about uneven coverage, uneven sound pressure levels (volume), lots of low-midrange rumble at the podium and a general lack of audio fidelity. He seemed like he was ready for a new sound system.
We asked what he had installed now. Bose 502A. No problem there. Was he using the system controller? Yes. How and where were they installed? In a center cluster, about 5-6' directly above the podium microphone (see below). Uh oh.
This is not how to do it.
Two things stuck out to us. First, the center cluster was low. Of course, the ceiling is low, too, so options were limited.
Low frequency pattern control is a big issue that most don't consider when it comes to a new system. The short story is that...
What are the differences between the Shure QLX-D and ULX-D?
We get this question a lot, and thankfully, we found some information from Shure that neatly summarizes the facts and confirms our suspicions about audio quality. The following article is a Tech Tep from the Shure Applications Engineering team.
Typical Applications for QLX-D - corporate events, live music, higher education campuses, houses of worship, hotels, conference centers. For a corporate installation, consider QLX-D if all the receivers are on the same floor and/or use the same Ethernet network. For live music, consider QLX-D for a small or medium-size concert hall.
Key Differences between QLX-D and ULX-D
In terms of audio quality, reliability, and RF performance, QLX-D and ULX-D are the same. The primary differences are network sophistication and RF flexibility.
Electro-Voice Roadshow 2014 - the place we found a new favorite
If you've followed what we've written for long enough, you've seen us switch gears and to offer new favorites of powered choir microphones, earset microphones, powered speakers, line arrays, video projectors and equipment in general. And we think that's okay. If we didn't have new favorites, that would mean that our suppliers were still turning out the same old stuff in new packages, and that's just not the case.
In September, we were invited by Electro-Voice to come out to one of its roadshows. Thankfully, it was here in Columbus, so we didn't have to travel very far, and they fed us lunch. That's always a plus.
For about two hours, we listened. We sat outside and got to hear most of the Electro-Voice product line at a full-sized outdoor stage. The picture above is not the Roadshow, but just a file photo.
At the Roadshow, we heard larger-format line arrays for festival-type use, line arrays for permanent installation right beside those larger arrays, new powered speakers on stands next to large-format conventional speakers with small format installation speakers close by, and more. Events like these are really rare, so we always try to get out to hear the lineup, especially when it's in a real-world setting.
All of it was pretty impressive, but one particular speaker group really stood out - the new ETX powered speaker family. Shown in the photo above.
We heard a 2-way 10". I like small loudspeakers, so I was immediately interested. One listener interrupted and asked "is the sub on?" It wasn't (we were all fooled). Amazing bass response. Then the demonstrator added the sub, switched it off and them fired up the 12", added the sub to that, fired up the 15", added the sub. Eventually, he moved to a 15" 3-way with two subs underneath. We heard $100,000 line arrays, we heard $500 smaller speakers, and people kept asking to listen to the ETX again. So we listened some more.

What others say
Just a quick note on the two Da-Cappo DA12's our church purchased from you last week. Wow! They really reproduce the voice accurately, whether speaking with the omni, or singing with the cardioid. This was money well spent! Thanks for great advice, as always.
