    Go here to read part 1 of this series.————————————————— “In the beginning there was graphic EQ.” The first standard tool for system equalization was the graphic equalizer. Early versions were 10 bands at octave intervals, but the 1/3rd-octave version took over the market completely by the late 1970s. The 31 bands were standardized to a series of 1/3rd-octave intervals beginning with 31 Hz. There was no standardization of the shape of the filters, however. One model might use 1/3 octave… 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

    In this article we’ll investigate how the speed of sound in air is, for all intents and purposes, exclusively temperature dependent within the audible bandwidth of our typical applications. There are some popular misconceptions on this subject related to pressure, density, and other effects that are addressed here. The speed of sound is the distance traveled per second through an elastic medium. The medium is composed of molecules held together by intermolecular forces. Sound energy passes through the medium by… 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

    A concert sound system is, in reality, two completely separate sound systems, joined at the hip by a split snake. Each system requires a skilled engineer, but the skill-sets between the two differ vastly. The thing that baffles me is how ill regarded the position of monitor engineer is among my brethren. It can be easily argued and defended that the monitor engineer works twice as hard as everyone else on the crew, unless he/she is lucky enough to have… View this story

      A loudspeaker array is a collection of loudspeakers that is assembled to achieve a coverage pattern that cannot be achieved with a single device. Arrays are most commonly implemented to achieve a wide horizontal coverage pattern from a position on or above the stage. The “perfect” array would be a collection of loudspeakers whose radiation pattern was indistinguishable from a single (hypothetical) device that provided the needed pattern for the audience area. Many attempts have been made to solve… View this story

    We live in the present and plan for the future. Every once in a while it can be interesting to look back at our history and see he we got here. This puts things in perspective and helps us see what’s coming. The essential challenges to tuning a sound reinforcement system, a process we now call optimization, haven’t changed in 40 years, and neither have the laws of physics. But the tools and techniques of the trade have changed dramatically,… View this story

    This article is provided by ChurchTechArts.   I recently had the opportunity to teach a class on main sound system coverage and intelligibility at NorthWest MinCon in the Seattle area. We had a great group show up, and it was a lot of fun talking about the process of designing PA systems. While I can’t condense the entire class into a single blog post, I thought it would be good to hit some of the highlights. Here are four design… View this story

    speaker distortion
    Michael MacDonald 03/31/16 05:47 AM,
    Almost everybody in the pro audio business is a specification or “spec” junkie. From folks on the recording side to the sound reinforcement practitioners, we all want every detail of the technical performance of every piece of equipment in a system. Specs seem extremely important, particularly those that represent a numerical improvement from past products, which are heralded as an advantage.  But man cannot live by specs alone. Quite often, those who turn to specifications to answer questions should instead… View this story

    loudspeakers
    Bruce Main 03/28/16 06:18 AM,
    It wasn’t too many years ago that most shows were supported with trapezoidal point-source loudspeakers that were either horn loaded or front loaded. There were numerous touring companies providing proprietary loudspeaker systems, some well engineered and some not so well. Rigging was often an afterthought, and many systems were ground stacked. Companies sprang up that did nothing but design and build aftermarket flying hardware to support both proprietary and manufacturer loudspeakers. Depending on the combination of rigging and loudspeakers, the… View this story
