    Provided by Live Sound Advice.   One of the most common questions that comes up on many live sound forums is how to stop noises in a sound system. I’ve been doing a lot of experimenting on this subject over the past several years, plus I’ve been battling sound system noise such as hum in the field for more than 45 years, so here’s my observations on sound system noise and what to do about it. Before having any chance… View this story

You can read and comment on the original article here. Reverb is one of the most interesting aspects of digital signal processing effects for audio. It is a form of processing that is well-suited to digital processing, while being completely impractical with analog electronics. Because of this, digital signal processing has had a profound affect on… View this story

    This article is provided by Commercial Integrator   Have you ever seen or given a sales pitch that went like this:“Take a look at the proposal. If the price is too high, just let me know what will work for you and I’ll see what I can do?” Stop! You have just handed your prospective client a proposal and are already offering a price break. Why did you even bother to put a price on it? Take A Step Back… View this story

    A recent conversation with another engineer got me thinking about experiences that shaped my skills. While in the trenches, certain restrictions and limitations were aggravating and occasionally provoked fits of rage. However, in hindsight, those same events were actually beneficial to developing my skills. Budget Restrictions Many, many…. many years working with churches teaches you one incredibly important skill… Making do with what you have. Part of what established me as a moderately well-respected system installer was my understanding of… View this story

    This article is provided by Rane Corporation.   Editor’s Note: This article was originally published through The Rane Library in 2005, yet the information is as relevant now as it was then. Acoustic feedback (also referred to as the Larsen effect) has been roaming around sound reinforcement systems for a very long time, and everyone seems to have their own way to tame the feedback lion. Digital signal processing opened up the microphone to some creative solutions, each with its… View this story

    Line arrays and large-format loudspeakers get the lion’s share of attention, but in reality most sound companies don’t need a large system at every event. Many can be handled with smart deployment of more compact 2-way loudspeakers, usually accompanied by a small quantity of subwoofers. While we tend to think of loudspeakers along these lines as entry-level “speakers on a stick,” numerous manufacturers have developed higher-quality models that go beyond that metric, yet they’re still below the radar in terms… View this story

      Crossover networks are not unique to audio and acoustics. The role of such a network is to produce a transition between two systems of differing capabilities. In a loudspeaker system, an increased overall bandwidth is achieved by splicing together two or more lower bandwidth transducer responses. An individual woofer, squawker and tweeter can form a full-range system through the use of a crossover network. Let’s look at some other systems that require similar transitions between their individual components. Several… View this story

    As an audio technician, my ears have the final say in how a system is tuned, but with the passing of time, they’re not quite as reliable as they used to be. As a result, I’m increasingly relying on measurement systems to help with dialing in the PA. I also utilize SPL apps on my phone and iPad to help monitor volume levels, and that’s worked out well. So when I first saw the iSEMic 725TR measurement microphone from iSEMcon,… View this story

Posted by Jay Last weekend I refused to let a band roadie (did the setup but didn’t mix or anything) use their own stage drops at the front of the stage. One of the drops I did approve was a Hubbell 4-plex with the low profile plastic box. One I rejected was the same but broken and held… View this story
