    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 post

    Jeremiah Slovarp, a five-time Emmy-Award winner, began his career in the early 2000s as a location sound engineer on various films and commercials. Today, the active engineer and producer brings that knowledge with him to the classroom at Montana State University, his alma mater, where he teaches students at the School of Music tips and tricks for life in the audio industry. Among Slovarp’s go-to instructional tools is DPA Microphones’ d:vote 4099 Instrument Microphone. “We teach classical musicians to play… View this post

    church sound
    Chris Huff 12/04/15 10:02 AM,
    PSW Top 20 presented by Renkus-Heinz   “Can you come to our church and run sound in a few weeks?” “Can you run sound for my band next weekend?” Work as an audio geek long enough and you’ll get these questions, usually followed by the statement, “Don’t worry, we’ve got all the gear, you just need to show up.” Danger Will Robinson! I’ve been in these situations and one thing’s for sure: it’s never as easy as it sounds. Standard… View this post

    Primacoustic (a division of Radial Engineering) announces a comprehensive room acoustics analysis service that can be accessed through the company’s website. This free service invites the user to fill out a series of questions that will be used to determine the acoustic issues with the space. Questions cover: the purpose of the room, the size of the room, wall surface measurements, and existing floor and ceiling materials. A description of the way in which the room will be used, as… View this post

    rational acoustics
    Jamie Anderson 11/24/15 01:06 PM,
    Feed The Brain. The primary job of a measurement rig is to acquire electrical and acoustical signals and feed them to the processor so that it can analyze, compare, slice, dice, fold, spindle and mutilate those signals and produce multi-colored charts, graphs and the all-important squiggly lines. “But my software can produce squiggly lines all by itself without all those bothersome wires, preamps and microphones. Isn’t that enough?” Maybe. It depends on whether you are getting paid to pose or… View this post

    AaroniaUSA, a division of Kaltman Creations LLC, is now offering compact, cost-effective and portable (battery-powered) signal generators. Specifically, the new BPSG4 RF signal generator provides up to 4.4 GHz, while the new BPSG6 supplies up to 6 GHz. Both run up to 4 hours in battery operation and can be programmed with intelligent batch profiles. In addition, both models work with a user-friendly software interface providing real-time remote control via an integrated USB connector. Signal profiles can be created and… View this post

    The reshaping of entertainment production wireless operations in the U.S. is currently underway, and it will impact all wireless microphone, in-ear monitoring and intercom system users – including those working in church sound – in the near future. The shrinking UHF band, where the vast majority of wireless systems currently operate, will get even smaller with the 2016 commencement of the 600 MHz incentive auction to allow the mass introduction of white space devices. Almost all of the remaining UHF… View this post

    time
    Tom Young 11/20/15 03:56 PM,
    When traveling to different time zones, we need to correct our time-keeping tools in order to align our activities to the local standard time. Very simple. Likewise in sound reinforcement systems, we often encounter multiple sources of misalignment, albeit in much smaller time increments. The importance of these misalignments is often subject to debate, but with the advent of a wide variety of very good digital processing products, correcting such anomalies is no longer out of reach for most of… View this post

    SynAudCon is presenting Making Wireless Work, an in-person training workshop, at the Tuscany Suites in Las Vegas on Thursday, December 3 and Friday, December 4. Making Wireless Work will focus on wireless microphone technologies, frequency coordination, band planning, RF fundamentals, FCC and spectrum allocation issues, and site survey commissioning procedures. Another topic to be covered is the effect that the upcoming 600 MHz incentive auctions will have on professional audio. Top wireless professionals, including noted RF consultant James Stoffo as… View this post

    subwoofers
    Jerrold Stevens 11/16/15 07:10 AM,
    PSW Top 20 presented by Renkus-Heinz   “Subwoofers should be located on the floor if at all possible.” This is one of those classic bits of audio “conventional wisdom.” I hear it from system operators on nearly every project. But is it true? If we look at the physics of sound, we learn that, as with most things in the world of audio, “it depends.” So let’s start by discussing why the floor might indeed be a good place to… View this post
