    phantom power
    Bruce Bartlett 06/21/16 06:22 AM,
    This article is provided by Bartlett Audio.   Unsure about phantom power? Let’s clear up the mystery. Nearly all mixing consoles and audio interfaces provide phantom power at their microphone input connectors. Most condenser mics need phantom power to operate, so you simply plug the mic into the mixer to power it. But the ways we use and connect phantom power can make a big difference in how well those mics work. So what, exactly is phantom power, and how… View this story

      How much power can an audio amplifier produce? As you might expect, “it depends.” I will approach this from two angles—in theory and in practice. This article will deal with the theory. Part 3 will show how things play out in the real world. Importance Of Efficiency Amplifiers don’t make power. They convert it. Any audio power that comes from your amplifier must in turn come from the utility outlet that it is connected to. This is why the… View this story

    Provided by Live Sound Advice.   No, it’s not the name of an insurance company or a European sports car—GFCI is an abbreviation/acronym for Ground Fault Circuit Interrupter. They’ve been required in many localities for electrical outlets located near sinks or the outside of residences since the early 1970s. The two types of GFCIs you’ll encounter are either built into the power outlet itself (Figure 1, left) or inside the circuit breaker at the power panel (Figure 1, right). Both… 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

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
