Tim Vear 12/12/11 03:30 PM,An important consideration in microphone use is acoustic interference, which can occur whenever delayed versions of the same sound are mixed together, acoustically or electrically. With mics, this may happen in several ways: mics of reverse polarity picking up the same sound, multiple mics picking up the same sound from different distances, a single mic picking up multiple reflections of the same sound, or any combination of these. The results are similar in each case, and include audible peaks and… View this story

Jerrold Stevens 05/11/11 06:28 PM, 2 CommentsLike me, I’m sure you’ve heard the statement made in the headline of this article from quite a few sound folks, some of them real “heavy hitters” in the business. While some of them may have “golden ears,” I think these folks may be missing some of the finer points of system equalization, or more appropriately, system “optimization,” and the shortcomings of human hearing. So let’s see if we can break this down and arrive at a reasonable conclusion. First,… View this story

Keith Clark 04/20/11 01:14 PM, 0 CommentsIn the world of professional sound design and installation, there’s an old adage that goes “your system is only as good as the weakest component in the signal chain.” This is especially true of a sound system’s loudspeakers. They are the last link in the chain, directly responsible for communicating everything that’s been done to the signal along the way. The Basics One thing’s for sure: if a system sounds lousy, the listening audience will automatically shift their gaze first… View this story

Mike Wireless 03/24/11 02:38 PM,One of the topics that I’ve seen poorly understood, and even deliberately used to mislead people, is the issue of wireless microphone transmitter power and the effects said power has on system performance. Let’s start with the basics: all things being equal, more transmitter power = more range for the system, but not in a linear way. In broad terms, when discussing analog wireless systems, the receiver wants to see a signal from a transmitter that is at least about… View this story

Mark Frink 02/04/11 03:09 PM, 0 CommentsThis is the 40th anniversary of Altec Lansing’s passive third-octave “continuous” equalizer that began modern sound system equalization. It didn’t start as a graphic equalizer, but rather, was three rows of eight knobs on third octave centers. A companion third-octave real-time analyzer, three rows of eight VU meters, provided a means to measure a sound system. Subsequent Altec EQs replaced the knobs with a row of sliders, earning the name “graphic” because their positions provide a graphic display of the… View this story

Joe Wisler 02/03/11 09:50 AM, 0 Comments“You know, I’ve been doing sound here at my church for about two years now, and there are a couple of things that aren’t quite clear to me. First, where’s the bass and treble control? And, what are these knobs for - the ones on the console labeled high, mid and low?” I’ve heard questions like this posed more than once by people who do sound at their churches. And they’re great questions. Remember - we’re all in this together!… View this story

Neil Thompson Shade 01/27/11 10:08 AM, 0 CommentsWhy should one bother trying to understand basic acoustics? The most simple (and correct) answer is that study of basic concepts enables one to sort through the truth, semi-truth, myths and flat-out errors that pervade the pro audio industry. The fundamentals of acoustics (and physics) do not change, although some “experts” try to prove otherwise. New equipment, toys and theories come and go, but the basic building blocks of sound and its related concepts do not. If university level training… View this story

Dave Dermont 07/26/10 06:34 PM, 2 CommentsThere are advantages to getting older. Years of learning something new at every gig add up to that thing we call experience. You remember how well the first Soundcraft console you ever used responded to your touch. You recall, despite its simple interface and lack of things to tweak, how great the reverb of a Lexicon PCM-60 sounded. Another advantage to getting older is that the gear you lusted after as a youngster becomes affordable. The downside of this can… View this story

PSW Staff 09/01/09 03:48 PM, 0 CommentsThe ongoing Coldplay Viva La Vida concert tour has all band members utilizing Sensaphonics custom earphones and Sennheiser wireless systems. Further, all four band members upgraded from the classic ProPhonic 2X-S to the Sensaphonics 2MAX. “Most of the backline crew also have Sensaphonics IEMs,” says Monitor Engineer Chris Wood. “We have found the drivers to be very reliable. I can’t recall having a problem in the eight years we have used them.” A few wedges can still be seen on… View this story

Mark Frink 09/01/09 10:24 AM, 1 CommentThis time in Real World Gear we look at the big guns - large format line arrays, those with 12-inch and larger woofers. Line arrays are modular, multi-way enclosures arrayed in vertical columns, with their cabinet’s geometry optimized to provide full-frequency transducer coupling from one enclosure to the next along the height of the array. This is achieved at lower frequencies with cone transducers forming a column from one cabinet to the next, at frequencies where the distance between their… View this story
