    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 post

      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 post

    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 post

    Editor’s Note: Here’s an interesting thread from the PSW Live Audio Board (LAB) forums. It’s lightly edited for grammar and formatting. Enjoy. Posted by Jay Last weekend I refused to let a band roadie (did the setup but didn’t mix or anything) use their own stage drops at the front of the stage. One of the drops I did approve was a Hubbell 4-plex with the low profile plastic box. One I rejected was the same but broken and held… View this post

    PSW Top 20 presented by Renkus-Heinz   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… View this post
