    rational acoustics

    Feed The Brain. The primary job of a measurement rig is to acquire electrical and acoustical signals and feed them to the processor so that it can analyze, compare, slice, dice, fold, spindle and mutilate those signals and produce multi-colored charts, graphs and the all-important squiggly lines. “But my software can produce squiggly lines all by itself without all those bothersome wires, preamps and microphones. Isn’t that enough?” Maybe. It depends on whether you are getting paid to pose or… View this story

    church sound
    Keith Clark 11/23 07:20 AM,
    The scale and complexity of production at larger churches in the U.S. has grown exponentially over the past two decades. At the higher end of the scale, both the technology and expertise of the tech team is strikingly similar to that of arena-level concert tours. Case in point is Community Bible Church (CBC) in San Antonio, the seventh largest church in the U.S. with more than 25,000 members attending services campus-wide each weekend. Currently celebrating its 25th anniversary, the interdenominational,… View this story

    “Subwoofers should be located on the floor if at all possible.” This is one of those classic bits of audio “conventional wisdom.” I hear it from system operators on nearly every project. But is it true? If we look at the physics of sound, we learn that, as with most things in the world of audio, “it depends.” So let’s start by discussing why the floor might indeed be a good place to put subwoofers. Placing any loudspeaker against a… View this story

    We’re currently in-between touring seasons. Cables and snakes have been tested and repaired, wood painted, and cases treated to fresh new stenciling. All racks have been repackaged to their standard configurations, trucks subjected to annual maintenance, and warehouse floor swept - twice. Aside from a stray show here and there, for many hire companies, things are pretty quiet. Yes, these are the days that turn sound company owner and manager thoughts to Alternative Revenue Sources (ARS). The contracting/install market is… View this story

    The new PreSonus Eris Series active studio monitors, designed for the budget-conscious studio seeking accurate and powerful reference monitors, make a strong first impression. The series incorporates a proprietary Midwoofer-Tweeter-Midwoofer (MTM, also known as “D’Appolito”) configuration, utilizing matched midrange drivers working together to create the effect of one much larger driver. The E44 is outfitted with two 4.5-inch, custom-woven Kevlar LF/midrange drivers, while the E66 uses 6.5-inch versions. Both models have a 1.25-inch, silk-dome HF driver centered between the mid/low… View this story

    After several years designing and installing sound systems for small- and mid-sized churches, I discovered an unobtainable goal that we tend to pursue, even though we know it’s a mirage. I’m referring, of course, to the concept of idiot-proofing. A recent trade show visit had me concerned about the way a lot of gear is being marketed. At least to me, it appears that most manufacturers are working to eliminate the human element in purporting to design equipment that simply… View this story

      The reverberation time (RT) is one of the most fundamental room measurements. It gives a broad brush stroke description of the general acoustical behavior of a space, paving the way for the use of other metrics to determine clarity and direct-to-reverberant ratios. Wallace Clement Sabine was the first to formalize the RT into an acoustic metric. His method of measurement involved a program source, a stopwatch and a quiet room. Sabine determined that 60 dB of room decay was… View this story

    ProSoundWeb presents at least two feature articles every day of the working week, meaning that there are 40-plus long-form articles highlighted each and every month. That’s a lot. In fact, so much so that we got to thinking that it would be handy to present a round-up of the most-read articles for those who might have missed at least some of them the first time around. Here we kick off with the top 5 most-read articles on PSW for the… View this story

    church sound
    PSW Staff 10/29 12:11 PM,
    This article is provided by Gary   A few years ago I was visiting with my friend Chris Walker,  the worship leader at Covenant Life Church in Grand Haven, MI, when he dropped the term “tech ninja” on me.  I laughed and thought of the Teenage Mutant Ninja Turtles. I imagined a green shell-clad sound guy with an assortment of weapon stashed in his belt. (Not to mention the shell would be nice to be able to hide in… View this story

    This article is provided by Commercial Integrator   You walk into the office of a local architect and say, “Hi, I would like to tell you about the house I want to build, and I would like for you to design it and create drawings so I can have a contractor build it, and I want you to do this for free.” What do you suppose the architect would say? A while back, a well-known property development group called us… View this story
