    good sound system
    Bob Thurmond 03/05 10:06 AM,
    Editor’s note: This is a continuation of the discussion of factors of a “good” sound reinforcement system that begins here. A common complaint of audience members who have become familiar with a particular sound system, typically in a venue with a permanently installed system and which they visit repeatedly (such as a church) is that there are locations where sound is obviously better than at others. In other words, sound is not uniform throughout the audience area. In fact, this… View this story

    In late January, I was invited to a private demo of what looks to be some cool, and useful, new technology that blends advanced processing with a low-profile array of microphones. The AM-1 from TOA Electronics is the result of a multi-year development process and will be released toward the beginning of Spring, 2014.  The AM-1 is a microphone system that shifts its coverage pattern in real time as a person moves away from “on axis” to one side or… View this story

    In early February, a group of professional audio veterans traveled to Washington, D.C., for a series of meetings with the FCC to voice concerns about the current and future regulation and operation of wireless microphone systems. The group was led by Mark Brunner of Shure and Roger Charlesworth of the DTV Audio Group, and included Joe Ciaudelli of Sennheiser, Henry Cohen of CP Communications, Jackie Green of Audio-Technica, Louis Libin of Broad Comm, Kevin Parrish of NBC Network News, Brooks… View this story

    As their name implies, large-format line arrays are designed for bigger concert and event applications. They’re powerhouses, and in many cases, are now much more than simply loudspeakers, better described as integrated systems. Many of the models we’re presenting here incorporate dedicated power and DSP packages (onboard or rack-mounted), as well as being outfitted with increasingly sophisticated control, networking, and optimization packages. Integral rigging is usually user-friendly and marked by precision. Driver configuration and enclosure design remain a defining factor.… View this story

    Life is all about circuits. In hydraulic circuits, a pump forces a fluid to flow, such as water through pipes or soda through a straw. In pneumatic circuits, a pump forces airflow down a path, such as the air conditioning system in your house or the air hose that you use to inflate your tires. We all know intuitively that pumps produce a pressure and rate-of-flow of something. A path must exist for the flow to follow, whether intentional (electrical… View this story

    Provided by Sweetwater.   Q: I’ve been getting quite a few questions from clients lately about UPS (uninterruptible power supply) systems.The problem is, most either want to run out to their local office supply store and buy what’s cheapest, which I’ve insisted probably isn’t the best idea, or they’re an audiophile who’s heard that on-line UPS systems are the way to go. What can I tell people who don’t understand the value of the (many) other types of UPS systems,… View this story

    equipment racks
    Philip Giddings 02/18 03:18 PM,
    Portable protected and shock absorbing racks provide the most protection to equipment and should be used in all demanding applications, such as for rental and touring systems and for delicate or expensive equipment. These racks come in three configurations: an inner sleeve and outer bonnet assembly; a shock mounted inner sleeve; and isolator mounted equipment rails. The most popular with touring sound companies is the inner sleeve and outer bonnet assembly. Inner Sleeve & Outer Bonnet The inner sleeve is… View this story

    The specification of a loudspeaker’s sensitivity is probably one of the most common, yet perhaps one of the most misunderstood. It’s common to see the magnitude response of a loudspeaker system reduced to a single number as a sensitivity rating. This is perhaps at the heart of the confusion. One would think that this metric should give some indication as to how loud a particular loudspeaker will be when reproducing a signal. One may also think that two loudspeakers with… View this story

    There’s a lot going on at JBL Professional these days, which I recently witnessed first-hand in spending a day at the company’s headquarters on the Harman Professional campus in Northridge, CA. My host was Paul Bauman, a delightfully unassuming man who was recently promoted to the post of associate director of tour sound based upon the success he’s fostered over the past seven years. To say that Bauman came to his current role with significant experience is an understatement. Working… View this story

    The performing arts center has a theatrical performance on Tuesday, a rock show Thursday, symphonies Friday and Saturday, and a jazz quintet Sunday – with ballet and opera the following week. Everything from spoken word to recorded accompaniment to live music is reproduced by the loudspeaker system(s), and with the price of tickets, the sound has to be clear, full, and intelligible.  The quality of what the audience hears is critical to their experience of the artistic performance, with focus… View this story
