    Provided by Live Sound Advice.   “You keep using that word. I do not think it means what you think it means.”—Inigo Montoya, The Princess Bride The Twitterverse was hopping last night with news of Canadian singer Grimes being “electrocuted” during a concert in Dublin. (Go here and #Grimes on Twitter.) While she was shocked on stage, she definitely wasn’t electrocuted multiple times. That’s because the word “electrocution” refers to death by electric shock. If she was indeed killed by… View this story

      For professional audio people, the word “power” usually conjures up visions of racks of amplifiers are used to drive the loudspeakers in a sound system. But the amplifier and other system components must have a stable power source from which to operate.  Thus the issue of power distribution, all the way from Hoover Dam to your sound system, is vital. Some of the principles of audio signal distribution in sound systems are borrowed directly from utility companies, and so… View this story

    Provided by Live Sound Advice.   I’ve been a professional audio engineer for 40-plus years and a musician for 10 years more than that, and during that time, I’ve witnessed hundreds of shock events on performance stages, recording studios, and even factory floors. A survey I ran on ProSoundWeb a few years ago revealed that 70 percent of the 3,000 musicians who responded had been shocked at least once on stage – some so severely that they were knocked unconscious.… View this story

      Here’s a handy quiz for checking your knowledge about audio power. Rather than submit you to the typical “right or wrong” questions with exact numerical answers, I’ve elected to provide a different means of self-evaluation. I can tell you up front that the answer to every question is “It depends!” But what’s really being asked is “WHAT does it depend on?” At first glance it may seem that the question is not even related to audio. Don’t be fooled.… View this story

He called this design error “the Pin 1 problem,” because it was an improper connection of the… View this story

    Hosa Technology introduces two new series of power cords, designed specifically for gear outfitted with Neutrik powerCON connectors. When properly installed, these connectors forge a secure connection that prevents accidental disconnects due to tripping over cables or bumping of equipment. PWN-200 Series Power Cords are designed to carry power from a normal wall outlet to a powerCON-equipped device. For those using power distribution boxes equipped with powerCON outputs, PCN-200 Series Power Cords feature powerCON connectors at both ends and are… View this story

    Editor’s Note: This article was originally published in the March/April 2000 issue of Live Sound International, and it still provides a wealth of valuable information on this important topic. Q.) What does a power amplifier do, anyway? A.) In a nutshell, a power amp takes your audio signal and provides both voltage gain and current gain to drive loudspeakers. The voltage gain is necessary because line-level audio runs around a volt, peaking at maybe 8 to 12V, and loudspeakers need… 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

    The Garland Theater in Spokane, Washington opened its doors in 1945. In 1999, Katherine Fritchie purchased the theater, realizing that the treasured venue needed some serious upgrades if it was going to continue to be a vital part of the community. Dedicated to revitalizing theater while maintaining its beloved history, Fritchie turned to local integration firm Hoffman Pro Systems to design and install a new AV system protected, powered and operated by a Furman SmartSequencer. “I have been working with… View this story
