    no shock zone
    Mike Sokol 02/05/14 03:12 PM,
    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

    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 for Ground Fault Circuit Interrupter or G-F-C-I. They’ve… View this story

    Craig Leerman 05/01/13 03:36 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

    What happens if a piece of suspended rental equipment is put in service and falls from its rigging, resulting in damage to the property, as well as to the technician installing it and perhaps even several other crew members? Besides destroying the rental equipment, there is a high probability that a lawsuit will follow. If you’re the unfortunate soul owning the piece of equipment that failed, you can count on being the primary defendant in the complaint. It’s at this… View this story

    By high voltage power distribution, we mean that the output power of the amplifier is converted to a high-voltage/low-current signal for transmission over long distances and/or small wire gauges. The advantages of the method include low cost and rather “bulletproof” systems. The downside of the method is that the transformers required present yet another filter for the signal to pass through, often degrading the audio quality. Since loudspeaker lines should always be kept as short as possible, the ultimate realization… View this story

    RCF has announced the launch of the DXT 9000 – a digital voice-alarm system with the brains of network technology and the soul of professional audio. The system can be viewed at ISE 2013 in Amsterdam, where RCF will be demonstrating it at booth 7H230 showing the DXT 9000 system’s capabilities in real-world applications. “From the word go, our goal was to design a voice-evacuation system that offered all the benefits of modern network technology: scalability, ease of configuration, reliability,… 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
