    At the Prolight + Sound show in Frankfurt, Yamaha has announced the release of the new PX Series of power amplifiers for sound reinforcement applications. The PX Series comprises four new models: PX10 (2 x 1200 watts), PX8 (2 x 1050 watts), PX5 (2 x 800 watts), and the PX3 (2 x 500 watts), and come equipped with both XLR and TRS inputs, and binding post, SpeakON and phone outputs. All models are driven by a newly-developed class D amplifier… View this story

    The majority of live shows and events present interconnect challenges. We need to interface our gear with installed house systems, recording or broadcast trucks, A/V companies, rental gear, and even equipment from our own inventory that has different connectors. My company’s inventory, for example, consists of various analog and digital consoles, some of which have 1/4-inch TRS (tip/ring/sleeve) connectors for outputs, while others have XLR connectors and still others are outfitted with some combination of both. As a general rule,… View this story

    Provided by Live Sound Advice.   “You keep using that word. I do not think it means what you think it means.”—Inigo Montoya, The Princess Bride The Twitterverse was hopping last night with news of Canadian singer Grimes being “electrocuted” during a concert in Dublin. (Go here and #Grimes on Twitter.) While she was shocked on stage, she definitely wasn’t electrocuted multiple times. That’s because the word “electrocution” refers to death by electric shock. If she was indeed killed by… View this story

      For professional audio people, the word “power” usually conjures up visions of racks of amplifiers are used to drive the loudspeakers in a sound system. But the amplifier and other system components must have a stable power source from which to operate.  Thus the issue of power distribution, all the way from Hoover Dam to your sound system, is vital. Some of the principles of audio signal distribution in sound systems are borrowed directly from utility companies, and so… View this story

    I’ve been a professional audio engineer for 40-plus years and a musician for 10 years more than that, and during that time, I’ve witnessed hundreds of shock events on performance stages, recording studios, and even factory floors. A survey I ran on ProSoundWeb a few years ago revealed that 70 percent of the 3,000 musicians who responded had been shocked at least once on stage – some so severely that they were knocked unconscious. I’ve also witnessed dozens of ground-fault… 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

He called this design error “the Pin 1 problem,” because it was an improper connection of the… View this story

    Hosa Technology introduces two new series of power cords, designed specifically for gear outfitted with Neutrik powerCON connectors. When properly installed, these connectors forge a secure connection that prevents accidental disconnects due to tripping over cables or bumping of equipment. PWN-200 Series Power Cords are designed to carry power from a normal wall outlet to a powerCON-equipped device. For those using power distribution boxes equipped with powerCON outputs, PCN-200 Series Power Cords feature powerCON connectors at both ends and are… View this story

    Editor’s Note: This article was originally published in the March/April 2000 issue of Live Sound International, and it still provides a wealth of valuable information on this important topic. Q.) What does a power amplifier 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
