    Welcome to our quiz featuring 20 questions about stage monitoring and related issues. This is somewhat subjective and largely intended for entertainment purposes—better known as FUN for short - -although there is fact and/or truth in many of the “correct” responses. Time for the obligatory non-apology: “We apologize if this quiz offends anyone. That is… er, is not... our intention. Besides, if you don’t like it, we’ll just claim you took it out of context.” Enjoy! 1) Why do vocal… View this story

    Feed The Brain. The primary job of a measurement rig is to acquire electrical and acoustical signals and feed them to the processor so that it can analyze, compare, slice, dice, fold, spindle and mutilate those signals and produce multi-colored charts, graphs and the all-important squiggly lines. “But my software can produce squiggly lines all by itself without all those bothersome wires, preamps and microphones. Isn’t that enough?” Maybe. It depends on whether you are getting paid to pose or… View this story

    When traveling to different time zones, we need to correct our time-keeping tools in order to align our activities to the local standard time. Very simple. Likewise in sound reinforcement systems, we often encounter multiple sources of misalignment, albeit in much smaller time increments. The importance of these misalignments is often subject to debate, but with the advent of a wide variety of very good digital processing products, correcting such anomalies is no longer out of reach for most of… View this story

    “Subwoofers should be located on the floor if at all possible.” This is one of those classic bits of audio “conventional wisdom.” I hear it from system operators on nearly every project. But is it true? If we look at the physics of sound, we learn that, as with most things in the world of audio, “it depends.” So let’s start by discussing why the floor might indeed be a good place to put subwoofers. Placing any loudspeaker against a… View this story

    In the world of sound there’s an old adage that states, “Your system is only as good as the weakest component in the signal chain.” This is especially true of a system’s loudspeakers. They are the last link in the chain and are directly responsible for communicating everything that’s been done to the signal along the way. Going beyond simply delivering sound into a room, they actually become a living physical element, dynamically interacting with their surroundings. In other words,… View this story

    In many ways, loudspeaker technology is the primary limiting factor in sound reinforcement system design and performance. Transducers are always problematic, having to comply with the laws of thermodynamics and all. Not only are they inefficient at turning electric energy into acoustic energy, they also add a significant amount of distortion to the signal during the process. Some years ago I was in Washington, D.C., doing research for a potential patent for a vibration reducing device, and I came across… View this story

      One of the most confusing subjects in audio? Loudspeaker power ratings. It’s generally accepted that a large loudspeaker power rating is a sign of quality and something to be desired. And it’s the performance metric that probably has the greatest influence on the consumer’s buying decision. But a closer look reveals that power rating is far less significant than other metrics regarding the performance of the loudspeaker. The term “power rating” requires further explanation to avoid misunderstanding. It’s tempting… View this story

    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
