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

Dave Rat 06/08/11 01:04 PM, 2 CommentsThose of us who indulge in live sound spend countless hours paying attention to every detail in the audio signal chain - comparing, pondering opinionating and deciding every issue that crosses our path. Does this mixing console sound better? Do I need to spend an extra $2,000 on a vocal compressor? Can you please move the guitar mic two millimeters to the left? Does phantom power really ruin ribbon mics? One question persists, however: to what end is all this… View this story

05/17/11 09:40 AM, 0 CommentsBefore working at Coventry University in Coventry, UK, I designed anesthetic machines in a lab that was two garages end to end. The lab was long and thin, rather like a railway carriage. There was no hint of the strange events that would unfold. As I arrived one morning, I reached for the door handle and came face to face with the cleaning lady who was in a state of distress. She told me she had just been crept up… View this story

Tom Lubin 04/08/11 08:15 AM, 2 CommentsThe sound of popular music can be clearly compared to other forms of seasonal commodities such as clothing fashion and hairstyles. Much as bell-bottoms, the hula-hoop, and whitewall tires have become fashion statements associated with certain times past, “the sound” of most records will in later times provide a key identifier in time stamping that music. Like fashion, some of these sounds periodically re-emerge; some become an ongoing fabric of music production, while others are never heard of again. We… View this story

Al Keltz 04/04/11 09:01 AM, 1 CommentMurphy’s Audio Law #10: “The probability of having sound system failure is inversely proportional to the amount of time remaining until the performance.” We’ve all experienced it - something in our system not working properly or not working at all, and too often, it happens just before the start of a performance. Although the first instinct might be to take a “shotgun” approach and start checking plugs, connections, cables, etc. in a random fashion (i.e., “panic”), a tried-and-true troubleshooting method… View this story

Kent Morris 04/01/11 09:25 AM, 0 CommentsEqualizers, by their nature and name, are supposed to redress imbalances in a sound system. Unfortunately, equalizers, whether graphic, parametric, or shelving in nature, are only as good as the person using them. Knowing where to turn the knob or push the fader is usually a dark science, but there is a light at the end of the tunnel. The first step in proper EQ technique is to realize the knobs go to the left better than they go to… View this story

Bob Thurmond 02/14/11 04:56 PM, 1 CommentThere exists a long list of important sound system characteristics that we have no meaningful way to measure or evaluate. Besides, the really important skill is to be able to listen, identify problems by ear and correct them on the spot, right? But is this realistic or just an elusive dream? Even if problems can be identified subjectively, they still need to be solved physically. Therefore, we must know exactly what, where and how much. These parameters can be learned… View this story

Keith Clark 02/08/11 10:00 AM, 0 CommentsCal Timmer has been a sound operator at Haven Christian Reformed Church in Zeeland, Michigan since 1989, and over that time, the church has moved from traditional services to a more contemporary style, including a praise band. The sanctuary was built in 1964, with a classic “shoebox” shape and a capacity of about 450. It’s an acoustically live space, and last year was outfitted with a new sound system better meeting the changing style of worship and the physical attributes… View this story

Andy Wood 02/07/11 06:18 PM,Many professional audio manufacturers are now actively producing their own proprietary network connection and control systems, thus enabling users to create and control products within the audio chain. While not a particularly new concept (Crown, for example, started the trend in the 1990s with the IQ computer control system for its amplifiers), recent years have seen a plethora of new solutions. Therefore, to partner this article on interconnection options, here’s a brief overview on the control and distribution solutions currently… 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
