    SurgeX has introduced Axess Manager and Axess Manager Mobile, new desktop and mobile apps designed to let users monitor power conditions and control power functions of multiple installations from a single location. They’ll be on display at the upcoming InfoComm 2014 show in Las Vegas at booth C8725. The new apps automatically discover devices on a network and allow remote management through an intuitive user interface on a desktop PC or mobile device. Axess Manager also offers enhanced management of… View this story

    power techniques
    Bill Whitlock 06/11/14 12:05 PM,
    When a system contains two or more pieces of equipment that are grounded, whether via power cords or other ground connections, a “ground loop” will likely be formed. (See Figure 1, below.) Although ground loops often involve power line safety ground connections, disabling them is both highly dangerous and illegal. However, devices called “ground isolators” can be inserted in the signal path to break the loop safely. This approach attacks the problem at its fundamental roots, while tampering with safety… View this story

      It is generally accepted that a large loudspeaker power rating is a sign of quality and something to be desired. It may be the performance metric that has the greatest influence on the consumer’s buying decision. A closer look reveals that it is far less significant than other metrics regarding the performance of the loudspeaker. The Basics The power rating of an amplifier describes its ability to do work on a load – like moving a loudspeaker. Generally, the… View this story

    Core Brands has introduced the Furman P-8 PRO C power conditioner, a 20Amp model joining the Classic Series that includes proprietary Furman technologies such as Series Multi-Stage Protection (SMP) and Linear Filtering Technology (LiFT). Housed in a rugged 1RU chassis with a minimalistic front panel and nine outlets, the P-8 PRO C is designed for power conditioning applications where front panel metering and illumination are not required. SMP surge protection circuit technology safely absorbs, clamps and dissipates transient voltages, eliminating… View this story

    radial engineering
    PSW Staff 04/07/14 06:57 AM,
    The new Radial Engineeringg SB-15 Tailbone, a high-performance signal buffer designed to sit at the beginning of the signal chain and drive multiple pedals without the added noise that can plague high-impedance circuits, is now shipping. The compact design begins with a standard hi-Z instrument input. The signal is then “tamed” using Radial’s proprietary Dragster load correction circuit to replicate the tone and feel as if connected directly to the amplifier. It’s then buffered via a 100-percent discrete, class-A unity… View this story

    Years ago, only car stereo makers would advertise “2,000 Watts Of Earth-Shaking Power!” But with the recent shift to switching power supply amplifier topology, we’re now seeing this with many pro-oriented products. What’s behind the hype? And what about properly matching power amplifiers and loudspeakers? Answers start by focusing on the fundamental unit of measure in audio, the watt. What is a watt? A strict definition according to Wikipedia: One watt is the rate at which work is done when… View this story

    Provided by Sweetwater.   Q: I help out with the audio at my church, and when our choir director asked me to add a loudspeaker for the choir loft, I thought it sounded a little challenging but not overly difficult. Well, when I connected the wire to one of the loudspeakers in the hallway, the entire system went dead! The plate on the back of the loudspeaker said something about 70.7 volts. What’s going on, and what the heck is… View this story
