    Festival season, in particular, means dealing with portable generators for show power. At performance venues, we hardly give power a second thought, simply handing our tails or feeder to the house electrician to tie into the “company switch.” Then we check the voltages at the distro end with a meter to make sure everything is connected properly, and that’s usually it – no more thinking about the power until it’s time to disconnect at the end of the gig. The… View this story

    Provided by Live Sound Advice.   No, it’s not the name of an insurance company or a European sports car—GFCI is an abbreviation/acronym for Ground Fault Circuit Interrupter. They’ve been required in many localities for electrical outlets located near sinks or the outside of residences since the early 1970s. The two types of GFCIs you’ll encounter are either built into the power outlet itself (Figure 1, left) or inside the circuit breaker at the power panel (Figure 1, right). Both… View this story

    The majority of live shows and events present interconnect challenges. We need to interface our gear with installed house systems, recording or broadcast trucks, A/V companies, rental gear, and even equipment from our own inventory that has different connectors. My company’s inventory, for example, consists of various analog and digital consoles, some of which have 1/4-inch TRS (tip/ring/sleeve) connectors for outputs, while others have XLR connectors and still others are outfitted with some combination of both. As a general rule,… View this story

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

    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

    LynTec announces the new Input/Output-Relay (I/O-R) board for the Remote Power Controller (RPC) platform. The I/O-R board expands RPC control options to include control for high-current contactors and UPS outlets, giving users more flexibility to connect and control complex systems on a single control platform, instead of using multiple control systems. This capability dramatically simplifies control setup and equipment operation. “High-current contactor control and outlet control are important to system designers as they add more UPS protection to their systems… View this story

    LynTec announces the CTR Series of high-current latching contactor panels for the company’s RPC Series controllers. In conjunction with the controllers, the CTR panels give users the option to control loads — either individually or as part of a sequencing group — that require more power than the maximum 30 amps a motorized circuit breaker can provide. “For some customers, installations are getting more complex, and current loads are getting more demanding. Meanwhile, changes in technology are leading to new… View this story

    LynTec announces it has added three new circuit count panels to its RPC line of remote-control breaker panels. The new panels make it possible for LynTec customers to add more circuits to their designs in the same horizontal wall space to control a greater number of components, as needed. “Space is always at a premium in electrical closets, which are usually too small to begin with. That’s why we made a point of adding higher-density panels to our offering as… View this story

    LynTec introduces a new timed event scheduling and astronomical clock capabilities on its Remote Power Control (RPC) and RPCR Automated Relay Panel products. Enabling timed control of on/off events at the circuit level, the innovations provide customers with the market’s simplest scheduling system to both program and use. “Equipping our RPC and RPCR solutions with timed event scheduling streamlines the setup and operation process, making any AVL-based installation much more efficient,” said Mark Bishop, president of LynTec. “Integrated directly into… View this story
