    This is the third segment in our series on design principles for distributed systems. For additional reading, be sure to check out the first and second articles within the series. A number of different patterns can be used for laying out ceiling loudspeakers, and each pattern can be implemented in different degrees of layout density. The pattern and density selected for an installation affect: • Evenness of coverage • Sound level capability of the system • Intelligibility • Power amplification… View this post

    Multiple sources of transient electrical noise (surges) including motors, HVAC equipment, photocopiers, power tools, etc, are present in all modern buildings. Surge energy conveyed by building power systems may also result from external sources such as nearby lightning strikes. To minimize the likelihood of injuries to personnel and damage to equipment due to electrical surges and accidental fault conditions, in North America the National Electrical Code (NEC) specifies that all exposed electrical equipment in building electrical systems is to be… View this post

    There’s a great moment in Forbidden Planet where Morbius tells the young Leslie Nielsen, intrepid captain of starship C57D, that it is “time for clarification.” The generationally challenged might want to check this flick out, as it is the progenitor of Star Trek, Star Wars – even certain aspects of Avatar.  “Clarification” in this case relates to the piano thing, as in a series of articles where I detailed a multi-mic technique for providing a very loud quad monitor mix… View this post

    An interesting development has occurred in recent times: folks have become much more aware that the acoustic space plays a critical role with respect to the final sound of the room. In other words, unless you “fix the room,” changing the sound system may in fact not solve the problem at all. And truth be known, bringing the room acoustics up to an “acceptable level” is often actually easier than setting up a PA system!  Testing One, Two, Clap Go… View this post

    This article is provided by Bobby Owsinski.   I think it’s safe to say that we’re at the end of the “album age,” and although the format will hold on for a while, it’s clearly waning in popularity. I’ve given this a lot of thought and have come up with what I think are the reasons, but be aware, they’re not all exactly what the popular wisdom assumes. So let’s begin with the six reasons why the album format has,… View this post

    Recently I took a compact line array rig out for a demo that was also a live event. The system included six full-range line array modules and four 18-inch-loaded subwoofers, driven by 12,000-watt amplifiers—and there were four more 18-inch subs sitting in the corner. The demo room was no bigger than 40 feet by 60 feet, and when I walked in and saw the size of the room, the scale of the system, and those four extra subs, my first… View this post

    church sound recording
    Bruce Bartlett 07/29/11 02:42 PM, 2 Comments
    At first glance, recording the audio of worship services might appear to be a relatively simple procedure. Just connect a recording device to the sound system, set levels, press “record” and you’re ready to roll, right? If only it were that simple. Still, it’s true that capturing quality recordings is not rocket science. The most important thing is to get off to the right start. Therefore, let’s start at the beginning and take a walk through the essentials. Every sound… View this post

    On some of my gigs, it’s not uncommon to see a person walk up to the house console, reach in front of the mix engineer at that console, adjust a knob or fader, and then walk away. For many in our business, mixing a live event is an individual operation, but my company has embraced a team approach to mixing. I call it mixing by consensus, and we transitioned to it primarily due to our work with corporate events. The… View this post

    This article is provided by Behind The Mixer.   Kent Morris said “live music is about the energy.“ That’s so true.  Where does that energy come from? How do you control it? And why can it sometimes be so hard to find?  All questions that will soon be answered. Phil Coulter, on his Highland Cathedral album, has a song that’s dedicated to the drums. It starts out with a few lines of verse that highlights the importance of the drums… View this post

    Click here to view/download a printable pdf of this article. Could anything be more confusing than a “power rating?” The question “How many watts” can have many answers, depending on whether we are talking about amplifiers or loudspeakers. There are also many variables regarding how power is measured and specified. The numerous variables have rendered “face value” power ratings virtually useless. Why is “power” so hard to quantify? One reason is because it is time-dependent and constantly changing - much… View this post
