    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

    Powersoft has introduced the DigiMod IK, a package that consists of three separate, easily assembled elements designed to help OEM manufacturers develop their own lines of active loudspeakers.  DigiMod IK brings a high degree of scale and flexibility to OEMs and integrators who require Class D amplification technology for loudspeaker applications in professional audio markets. By separating the DigiMod into three different components (which are easily connected by screws), Powersoft was able to deploy upgrades to each component. Components consist… View this story

    This article was first published several years ago in Live Sound International magazine, yet it still provides timeless reference information in clearing up misunderstood electro-physics of power amplification technology. Q.} What does a power amp do, anyway? A.) In a nutshell, a power amp takes your audio signal and provides both voltage gain and current gain to drive loudspeakers. The voltage gain is necessary because line-level audio runs around a volt, peaking at maybe 8 to 12V, and loudspeakers need… View this story

    The TransAudio Group has announced the release of two new MOSFET Class A/B design dual mono power amplifiers for studio applications from ATC – the P1 Pro and P2 Pro. They’ll be on display at this week’s 137th AES convention in Las Angeles at booth 1014. The P1 Pro delivers 150 watts per channel and the P2 Pro provides 300 watts per channel, both at 8 Ohms. The 19-inch rack-mount chassis has a front panel mounted standby button and L/R… View this story

      Here’s a handy quiz for checking your knowledge about audio power. Rather than submit you to the typical “right or wrong” questions with exact numerical answers, I’ve elected to provide a different means of self-evaluation. I can tell you up front that the answer to every question is “It depends!” But what’s really being asked is “WHAT does it depend on?” At first glance it may seem that the question is not even related to audio. Don’t be fooled.… View this story
