    This article is provided by SoundGirls.org   I meet a lot of sound engineers and techs around my age (mid-20s) that strictly stick to audio and don’t dare to touch anything else, whether it be to stay focused on audio or to not get roped into something they don’t particularly want to do. There isn’t anything wrong with this. Laser-focusing on one discipline can yield some great results. I know that my passion lies in audio, live sound especially. I… View this story

    PSW Top 20 presented by Renkus-Heinz   The much-discussed auction of the 600 MHz frequency band is happening in the U.S., and it may well affect present wireless systems as well as related issues such as frequency planning/coordination. It’s important for everyone who works with creating the content that will stream on the mobile devices when the spectrum is cleared to understand the present situation and to be planning for the transition to different frequency bands.  Several leading pro audio… View this story

    This article is provided by Commercial Integrator   As my partner and I have been growing our business over the past 11 years, there have been times, especially in the beginning, where we would take on clients that turned into time-sucking vortexes of frustration. Not every customer is a good one. The customer really isn’t always right, and it might be time to let some of your existing customers follow through on their threats to leave. But how does one… View this story

    This article is provided by PreSonus.   The significance of balanced and unbalanced connections between audio devices, as well as the meaning of the terms, is often misunderstood. A balanced output can be designed, constructed, and connected in many ways, and there are several ways in which balanced and unbalanced devices can be interconnected. Balanced connections have a long history that dates back to the early days of telephony. The phone company runs thousands of miles of unshielded cable between… View this story

      The most common reference distance for loudspeaker SPL specifications is 1 meter (3.28 feet). The choice is one of convenience – any distance will do. The 1 m reference simplifies distance attenuation calculations by eliminating the division required in the first step:   Loudspeakers must be measured at a distance beyond which the shape of the radiation balloon remains unchanged. The changes are caused by path length differences to different points on the surface of the device. These differences… View this story

    This article is provided by Rane Corporation.   Constant-voltage is the common name given to a general practice begun in the late 1920s and early 1930s (becoming a U.S. standard in 1949) governing the interface between power amplifiers and loudspeakers used in distributed sound systems. Installations employing ceiling-mounted loudspeakers, such as offices, restaurants and schools are examples of distributed sound systems. Other examples include installations requiring long cable runs, such as stadiums, factories and convention centers. The need to do… View this story

    Editor’s Note: Here’s an interesting thread from the PSW Live Audio Board (LAB) forums. It’s lightly edited for grammar and formatting. Enjoy. Posted by Brian Ever since digital consoles came out along with their attendant editing programs, everyone has joked about how one day we’ll be mixing shows from our house. Well, this week I took a large step in that direction by mixing a show in London from a comfortable seat in Washington DC. I should say this was… View this story

    This article is provided by Behind The Mixer.   One button that still looks pristine. No fingerprints. No worn finish. It doesn’t even have a name. Working in audio, it’s easy finding my way into a foreign sound booth. It could be it’s my station for an event or it might be that I’ve been invited in by the sound tech on duty.  Over the years, I’ve noticed one button that’s often not used. It’s the fixed-point high-pass filter button… View this story

    Sometimes the differences between a good and a great system design are the “little things” like cables, connectors, mounts, stands, rigging, and so on. So let’s shine a bit of light on these often overlooked aspects. Loudspeaker cables come in many styles and lengths but they all do the same thing, which is to provide two conductors to connect a passive loudspeaker to its respective amplifier output. The rule of thumb is simple: “Use the largest gauge cable possible and… View this story

    impedance
    Jonah Altrove 10/06 08:42 AM,
    It may not seem so at first blush, but there are a few concepts as pervasive in live audio as the concept of impedance. It’s relevant to microphones, direct boxes (DIs), preamps, processors, amplifiers, loudspeakers, equalizers, crossover filters, and even the cables that connect them all together. In this article we’ll explore the principles of impedance, and examine how these concepts apply directly to our work in the field. Ohm Sweet Ohm In order to understand impedance, we need to… View this story
