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

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

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

Dave Rat 11/11/10 06:57 PM, 1 CommentHow fast do sound signals travel through the various parts of the sound system? Do sound signals travel faster in analog snake cables or fiber optic cables? Also, what about transmission through the air with wireless mics? And where do the true and relevant sources of time lag exist in a audio system? What I find really interesting is that sound signal travels at differing speeds depending on whether it’s in the form of electricity, or sound waves in air,… View this story

Pat Brown 10/12/10 12:48 PM, 0 CommentsFor most humans, there is nothing easier than breathing, seeing, smelling and hearing. We do these things without thought, and even take them for granted. Our senses were given to us to help us exist in a physical universe. They are transducers that allow physical stimuli to be converted into a form recognized by the brain. We are bombarded with stimuli every waking moment, and our brains are continuously processing the information to help us function in our environment. Of… View this story

Barry Rudolph 09/20/10 05:29 PM, 0 CommentsHave you ever wondered why some recording artists and producers are more successful in the studio at accomplishing their goals than other people who are equally or more musically talented? As a recording engineer, here’s what I’ve noticed about successful people in the studio. Vision I’ve found successful people come in all personality types from the very shy and soft-spoken to the boisterous extrovert but they all share a common trait: they have a very specific “vision” of their songs… 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
