    Courtesy of The Rane Library.   This article is provided by Rane as part of the Rane Library and originally appeared in the Syn-Aud-Con Newsletter, vol. 31, nos. 2 & 3, 2003 In his landmark 1994 AES paper, Neil Muncy described a common equipment design error that allows current flowing on the shields of audio wiring to enter equipment and cause audible interference. He called this design error “the Pin 1 problem,” because it was an improper connection of the… 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

    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 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

    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

    The idea that “dirty” power causes audio system noise problems has a nearly irresistible intuitive appeal - and there are dozens of companies ready to cash in on this widespread but mistaken belief. For example, here is a quote from a well-known manufacturer of power conditioning products: “Today’s residential systems contractors face unprecedented challenges where high resolution, trouble-free operation is required. From inducing AC ground loops, video hum bars, static bursts, damage from AC line surges and variable audio and… View this story
