    When measuring loudspeaker systems, the question of phase response often arises. I thought it might be informative to review setting the receive delay within a measurement system so that the displayed phase response is the “correct” one. I have the word correct in quotes above because for a given magnitude response there are an infinite number of equally valid phase responses. This is due in part to what is called propagation delay. This is simply the time of flight of… View this story

    Courtesy of Audio-Technica.   Question: VHF vs UHF vs ISM vs UWB: Which wireless system works best? Answer: The idea that UHF wireless systems are inherently better than VHF systems and that ISM (2.4 GHz) and UWB (6 GHz) systems are better than VHF and UHF systems is widespread. But while each system does offer advantages, one is not automatically better than the others, as each system can be limited by wireless regulations and the physics of wireless signals. This… View this story

    At some point, every freelancer considers the possibility of moving up in the world and buying their own big system. Some do it, some don’t. But everyone has their reasons for the final decision. After years of doing shows as a hired gun, I began to consider the niches in my market and ways to take my little business to the next level. I determined that the big hole in my local market was for a dedicated monitor rig. My… View this story

    PSW Staff 01/26 07:04 AM,
    The just-concluded 2016 NAMM Show in Anaheim was the largest and most inclusive event in the National Association of Music Merchants’ (NAMM) 115-year history, hosting a record 1,726 exhibiting companies representing more than 6,000 brands, a 7 percent increase in exhibiting companies over 2015’s event. The number of new companies also grew again, representing 409 of the total exhibiting companies. In addition to the new-to-NAMM names, 174 companies returned after a lapse of a year or more. “As we look… View this story

    This article is provided by Commercial Integrator   Maybe no one has so profoundly summed up the essence of building brand loyalty than Simon Sinek in his Ted Talk, “Start with Why”. If you haven’t watched it before, I recommend it highly. There are many great Ted Talks, but this is one that has stuck with me ever since I saw it. But I digress… Simon notes people don’t buy what you do or how you do it, but they… View this story

      Here’s a handy quiz for checking your knowledge about audio power. Rather than submit you to the typical “right or wrong” questions with exact numerical answers, I’ve elected to provide a different means of self-evaluation. I can tell you up front that the answer to every question is “It depends!” But what’s really being asked is “WHAT does it depend on?” At first glance it may seem that the question is not even related to audio. Don’t be fooled.… View this story

    Courtesy of Acoustic Geometry.   There’s a moment early in the movie “Men In Black” – after a big green alien has put up ‘all his hands and flippers’ (and was then blasted to goo) – where an older, tired-out Agent D says to Agent K “They’re beautiful, aren’t they?” K replies “What?” And D says “The stars. We never just – look anymore.” I’m in the sound business, so I don’t have to worry about blasting creatures into goo… View this story

    As referenced in the article “When the show hits the fan,” there was a gig we pulled off without any of our gear. That’s right. The truck never showed up. In that same article, I explained the dark art of staying calm and resolving issues without inciting panic in those who carry the check books. For this particular adventure, the job of driving hundreds of thousands of dollars worth of our precious equipment from Georgia to Texas was given to… View this story

He called this design error “the Pin 1 problem,” because it was an improper connection of the… View this story

    The reshaping of entertainment production wireless operations in the U.S. is currently underway, and it will impact all wireless microphone, in-ear monitoring and intercom system users – including those working in church sound – in the near future. The shrinking UHF band, where the vast majority of wireless systems currently operate, will get even smaller with the 2016 commencement of the 600 MHz incentive auction to allow the mass introduction of white space devices. Almost all of the remaining UHF… View this story
