    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

    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. I’ve also witnessed dozens of ground-fault… View this story

    Excerpted from JBL Professional Technical Note Volume 1, Number 14: “Basic Principles for Suspending Loudspeaker Systems.” Design Factor Design factor is a term used by the rigging industry to denote theoretical reserve capability. The rated capacity / of all lifting and hanging equipment b based upon the nominal strength of the equipment reduced by the design factor. Design factor is a number representing the fraction of equipment nominal strength chosen to be appropriate for the particular application. Rated Capacity =… View this story

    Craig Leerman 09/23/15 01:46 PM,
    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

    With an eye firmly set on the issues that concern the entertainment technology industry, PLASA is once again hosting the Rigging Conference alongside its PLASA London event. Now in its sixth year, this unique event will feature 20 plus international speakers and panelists attracting in excess of 150 delegates, 30% of which attend from over 20 different overseas countries. This year, safety, regulatory issues and truss design are the hot topics that will form the basis of the Conference, which… View this story

    To most of us working in professional production, rigging refers to flying loudspeakers, truss, lighting and scenery in the air. It’s a black art performed by a secret society of stagehands called “riggers” who somehow have managed to defeat the laws of physics and get things to stay aloft. Rumor has it that these riggers even have their own handshake and a secret underground temple where they sacrifice old shackles into a volcano to ensure a good rigging season next… View this story

    Provided by HOW To Church Sound Workshops. &nbsp Every year, hundreds of musicians and audio techs suffer serious electrical shocks while on the job, and these incidents have the potential to be fatal. Therefore, it’s imperative to have a basic understanding of electricity to avoid possible electrocution, and further, this knowledge can help protect your equipment from going up in smoke. GFCI? No it’s not the name of an insurance company or a European sports car, GCFI is an abbreviation… View this story

    Provided by the No Shock Zone.   In part 1, we covered what voltage is and a bit on how it’s measured. Here let’s look at how to use a basic digital voltmeter to measure any power outlet or extension cord for proper voltage. The reason this procedure is so important is that sometimes venues do crazy things with power outlets. For instance. I was teaching a seminar last year in a “gymnatorium” and plugged in my little demo rack… View this story

    Provided by the No Shock Zone.   Most musicians really don’t want to learn about electrical engineering, or even how basic electricity works. Everyone, however, should learn how to test for and avoid electric shocks on stage. Guitar amps and mixing boards as wired from the factory are inherently safe, but they can become silent-but-deadly killers if plugged into an extension cord or wall outlet that’s improperly grounded. This is because guitars are held in moist hands while wet lips… View this story

    Stage rigging involves machinery. The various components of the system move and, because of that movement, the parts of the system will eventually wear out. That is the primary reason for having your stage rigging inspected. If that’s not motivation enough, there are several other reasons for an annual safety inspection. The people using the equipment may not know how to operate it properly, and therefore may cause damage to some of the parts. The equipment may not have been… View this story
