    As audio engineers, we’re constantly presented with choices that involve compromise and give and take. Many of these are budgetary and/or based on realities of what’s available or possible for a given application. Tradeoff, TANSTAAFL and triage are underlying principles to my decision-making process in the design and optimization of sound systems. The concept of the tradeoff is simple: give up something to get something. TANSTAAFL is an acronym created by sci-fi writer Robert Heinlein: “There ain’t no such thing… View this story

    Some in audio think that the term “rigging” only applies when loudspeakers are flown, but it also pertains to lesser endeavors such as placing a single loudspeaker on a tripod stand. The bottom line is that for any piece of production gear not sitting directly on the ground, steps must be in place to insure that it does not fall and injure someone (or worse). The Occupational Safety and Health Administration (OSHA), the U.S. agency that sets and enforces work… View this story

    Visceral, deep, percussive, tight, punchy – just some of many words used to describe bass response. A prominent low end forms the foundation for many styles of music and helps get the audience moving. Subs are specialized loudspeaker cabinets, typically operating somewhere inside the range between 20 Hz and 150 Hz, and they usually cross over into the full-range mains around 100 Hz. Especially toward the bottom of the range, these LF sounds are felt in the body as much… View this story

    line array
    PSW Staff 08/14/15 12:43 PM,
    Compact line arrays are those we’ve defined as having low-frequency drivers measuring 8 inches or smaller. Array modules in this genre offer a relatively small footprint in terms of size, weight and cost, yet they are capable of delivering significant output. They’re conveniently portable due to the size/weight factor, and are suitable for a range of fixed installations as well. Compact arrays present a scalable solution – a single unit will provide main coverage to a relatively small space, and… View this story

    Previously, I addressed the impact of breaking and tapering a line of loudspeakers (here). Now let’s turn our attention to balconies. Everybody seems to love breaking main loudspeakers horizontally into left and right, but breaking them vertically into upper and lower? Not so much. We can be repeat offenders when it comes to multi-main horizontal breaks, such as a parade route or racetracks. Multi-mains can go vertical as well, although it’s unlikely that we’ll expand beyond two elements. Vertical expansion… View this story

    studio monitors
    M. Erik Matlock 07/29/15 08:48 AM,
    Out of the box, my first impression of the new Les Paul Reference Monitors from Gibson was that I didn’t even care what they sounded like. They’re absolutely gorgeous. My room received an instant aesthetic upgrade just by having them in there. The active (bi-amped), 2-way line offers 4-inch, 6-inch and 8-inch carbon woofer options, each joined by a 1-inch carbon-coated titanium tweeter in a front-ported, bass-reflex enclosure. The rear panel includes high- and low-frequency trim controls for tailoring, both… View this story

    Remember Pac-Man (originally “Pakkuman” in Japan), the video game that debuted in the 1980s? For the unfamiliar, Pac-Man is a yellow ball that opens its mouth to eat dots as it is guided through a maze while avoiding being touched by four ghosts. What’s Pac-Man got to do with loudspeakers? Well, if you ever see him on a prediction coverage map, chances are the directivity balloon of the loudspeaker was not fully measured. For a long time in pro audio,… View this story

    line array
    Bob McCarthy 06/01/15 07:31 AM,
    A friend of mine who’s not an audio engineer went to a show and later told me it sounded too loud and unintelligible. Plausible? Sure. Now try this: another friend said it sounded like the line of the loudspeakers had been broken. Still seem plausible? No?  I figure everyone knows what a broken line sounds like since it’s such a big issue for discussion in the audio community. Every time I tune a system or hold a seminar, someone tells… View this story

    Several years ago, a technique most commonly called “aux fed subs” has been developed for reducing low-frequency “muddiness” from front-of-house loudspeaker systems. This technique has resulted in considerable benefits over a wide variety of sound reinforcement applications, but there is confusion as to what it encompasses and what it accomplishes. Let’s clarify the details and describe the set up of an aux fed subwoofer system. We’ll also be addressing some frequently asked questions on the topic. In a traditional loudspeaker… View this story

    I will never forget one particular service call. A small church called me out to quote a new sound system. This room sat about 120 people, pretty standard size and shape for rural Georgia. They weren’t happy with the existing system and wanted it replaced. When I walked into the room, I saw a single, odd-looking loudspeaker mounted tight to the ceiling over the podium. The pastor and tech told me how much they hated the way it sounded. I… View this story
