    Whether it’s a large festival line array rig or a single loudspeaker on a stick, all audio systems have one thing in common and that’s a need for power. Before starting to design, build, or use any power distribution equipment, the local laws and electric code should be consulted. The place to start is the National Electrical Code (NEC), sponsored by the National Fire Protection Association (NFPA) and published every three years. The purpose of the NEC is to safeguard… View this story

    Switchcraft announce an addition to our HPC series of high current connectors for loudspeaker and power applications.  All HPC connectors are fully compatible with Neutrik Speakon connectors.  This updated 4 pole version (HPCC4FT) has the turn to lock latching mechanism that has become standard in these types of connectors. The existing version (HPCC4F) has an XLR-style push lock. In addition to loudspeaker applications,  HPC connectors are touch-proof, rated for 30Amps, and have been used for AC power applications.

    LynTec announces the addition of Telnet control to the company’s complete line of RPC series power control panels. Telnet expands RPC’s interface options, strengthening the lineup’s onboard monitoring and control capabilities from any remote location. “Installations are moving toward a shared Ethernet backbone, and we added Telnet to the TCP/IP protocol to meet the need for simple monitoring and control over the network,” says Mark Bishop, president of LynTec. “As a manufacturer, we have the most choices for control of… View this story

    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
