    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

    microphones
    Craig Leerman 12/08/15 06:55 AM,
    A lot of my work is with conferences and corporate meetings. The approach is slightly different in comparison to traditional music gigs, particularly when it comes to microphones. Wireless lavalier and headworn/earset microphones are common in “corporates,” visually discreet while allowing presenters to move about the stage and use their hands to demonstrate products or operate controls of computers and AV equipment. When the feed is going to a PA system, lavalier mics with a directional pattern should be used… View this story

    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 story

    Being organized and prepared ahead of the gig is a huge key for the independent audio practitioner, a.k.a., Lone Audio Ranger. As I write this article, I’m smack dab in the middle of a multi-day, mixed programming event – a live outdoor cooking show with lots of wireless, video playback, record feeds, musicians, and emcees. This event is impeccably organized with everyone on the same page, and for the most part, happy. I chalk it up as a success. Yet… View this story

    A while back, I took some aspiring engineers to a trade show where some “antiques” were on display. Namely, CD/DVD players, along with a few analog multitrack players. Over the last 30 years, audio equipment has certainly followed the better-smaller-cheaper model of the computer industry. But like the computer market, repairs are no longer typically done at the part level. If the laser in a CD player goes bad, the chassis with the whole drive motor and optical track will… View this story

    church sound
    M. Erik Matlock 11/25/15 06:52 AM,
    Central Georgia is known for several things, including great food, classic southern culture, and a disproportionate number of churches. One church that’s stood as a beacon for many years is Christ Chapel, located on the north side of Macon. Currently serving as the audio director at the church, Jon Beachy and his family found everything they were searching for after relocating to Macon about 15 years ago. “We’d picked out a few churches to visit, and Christ Chapel was the… View this story

    church sound
    PSW Staff 11/24/15 07:05 AM,
    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 story

    PSW Top 20 presented by Renkus-Heinz   Among many of the recent entrants into the sound profession, I’ve noticed a lack of knowledge when it comes to wiring a stage. Perhaps it’s due to a lot of sound engineering schools being essentially studio-based courses. Or maybe it’s simply that it’s difficult to get a young mind to concentrate on something as mundane as running cable when there is a digital board with loads of lights and buttons sitting in the… View this story

    This article is provided by Church Soundcheck.com.   Skill: the ability to do something well; expertise. I recently asked the members of the Church Soundcheck (CSC) discussion board for their thoughts on the key technically oriented skills that a church sound tech must have (or strive for). It resulted in a lot of great input, which I’ve whittled down into this list. 1. Have a musical ear. When we say people have “good ears,” we mean that they know what… View this story

    Preserving our hearing is critically important, but that’s not what motivated me to write this piece. Really, I just can’t stand bad sound! To a certain extent, it used to be somewhat excusable if a live show was loud and didn’t sound all that great. Sound reinforcement systems have come a long way in the past decade alone, but ‘back in the day’” good clean power was harder to come by, and loudspeakers just were not designed to produce high-fidelity… View this story
