    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

    Multiple sources of transient electrical noise (surges) including motors, HVAC equipment, photocopiers, power tools, etc, are present in all modern buildings. Surge energy conveyed by building power systems may also result from external sources such as nearby lightning strikes. To minimize the likelihood of injuries to personnel and damage to equipment due to electrical surges and accidental fault conditions, in North America the National Electrical Code (NEC) specifies that all exposed electrical equipment in building electrical systems is to be… View this story

    Although the musicians we work with can tax our patience at times, and occasionally less than pleasant thoughts regarding them cross our minds, I seriously doubt that watching them fry from high voltage is something any of us would want to be responsible for. With that in mind, here are some basic precautions and tests to reduce if not eliminate the possibility of electrocuting our musical friends. Let’s start by stating that it is of the utmost importance that the… View this story

    ARX Systems has announced the addition of the new and unique USB I/O Universal Transformer Isolated USB Interface to its range of precision audio tools. The USB I/O is a true “plug and play” analog-to-digital and digital-to-analog pro audio interface and requires no special driver program installation on Mac OSX, Win XP and Vista. It features transformer isolated audio inputs and outputs, with new USB analog-to-digital and digital-to-analog converter chipsets that are incorporated into the circuit topology, allowing maximum headroom… View this story
