    If electrical wiring, from main breaker panel to outlet, consists of Romex and plastic J-boxes, an “isolated” or “technical” ground system is already in place. This is the case In most, but not all, residential wiring. However, when wiring consists of metallic conduit and J-boxes, as in most commercial buildings, an isolated safety-grounding scheme can sometimes reduce audio system noise. It is most applicable in situations where conduit may come in contact with building steel, water pipes, gas pipes, or… View this story

    Radial Engineering has introduced the IceCube IC-1, a compact balanced line isolator designed to fit inside a technician’s tool kit to eliminate hum and buzz caused by ground loops in audio systems. Radial sales manager Roc Bubel: “The use of isolators to solve noise problems is not new; small plastic units have been around for years. But the problem with these is that they were designed years ago - back when audio systems had limitations both with respect to signal-to-noise,… View this story

    Harman’s Crown Audio is now shipping the XLi Series, comprised of four new power amplifier models designed for entry-level professional live and installed sound applications. The XLi3500, XLi2500, XLi1500 and XLi800 deliver 1,000, 500, 330 and 200 watts per channel respectively (into 8 ohms; 2,700, 1,500, 900 and 600 watts in bridged mode into 8 ohms). All models have user-selectable input sensitivity to accommodate a variety of program sources that have low output signals and include balanced XLR and unbalanced… View this story

    Using our Stephen Hawking approved design for a real time machine, we journey to the dawn of the last century. It’s the summer of 1905 and in under a year the mechanical age will give way to the dawning of the electrical age. At this time the world is dominated by giant machines that can truly be called “heavy iron.” Machines like this: These 200-plus-ton behemoths are the quintessential embodiment of the leading edge of engineering and technology, and have… View this story

    I’ve been using rechargeable batteries in live production settings for more than eight years now, and writing about it for almost that long. In that time, I’ve come across three camps in the rechargeable battery debate. The first group has used them for years, loves them and wouldn’t consider going back to alkaline batteries. The second group has never used them, though most have heard the horror stories and are leery. The third group has tried them and had bad… View this story

    QSC has unveiled the GXD Series of amplifiers, providing power, performance and reliability coupled with the convenience of onboard digital signal processing. Housed in a 2U rack-mount configuration, GXD Series amplifiers are class-D devices for high power output in a light weight chassis design. They offer extensive loudspeaker processing capability to help users optimize and get the most from their loudspeaker systems.  DSP includes high- and low-pass filters (24 dB LR), 4-band parametric equalizer, signal alignment delay, and RMS/peak loudspeaker… View this story

    A new sound reinforcement system for the gymnasium at Ottawa Hills High School (just outside of Toledo, OH) incorporates Powersoft amplifiers driving EAW loudspeakers, implemented by Montpellier, OH-based Harter Sound. The catalyst for the sonic upgrade was lack of intelligibility. “They have a fairly young gymnasium as compared to most other schools,” notes Eric Harter, president of Harter Sound. “But the problem was that all the spectators, especially alumni and athletic directors, complained that they could not hear or understand… View this story

    With all of the new installation power amplifiers coming out on in the market—each with its own unique feature set—how is an integrator make a wise choice in order to maximize profit and minimize system complexity, customer callbacks, and overhead? Pressures to reduce environmental footprint, the dwindling of rack spaces, the inclusion of IT gear, the mix of high performance audio with background and paging systems, interest in the total long term costs of ownership have driven some substantial changes… View this story

    The recently renovated auditorium at Delano (Minnesota) High School has been outfitted with a new sound reinforcement system by design integration firm Farber Sound (Medina, MN), with power management from Furman implemented to protect premium components from JBL Professional, Crown Audio, BSS, Soundcraft and Shure. The 437-seat auditorium is used for activities ranging from assemblies to musical and theatrical performances, requiring full-range, highly intelligible sound reinforcement. To help insure the new system consistently performs, Farber Sound chose Furman ASD-120 AC… View this story
