    This article is provided by ChurchTechArts.   One of the most fascinating topics I’ve ever written about has to be rechargeable batteries. I’ve tweeted about and read countless comment threads on the topic and there seems to be three camps of people in the rechargeable battery debate. The first group has used them for years, loves them and wouldn’t consider going back to alkaline batteries. The second group has never used them, though most have heard the horror stories and… View this post

    Provided by Sweetwater.   Q: How does balanced power help to solve ground loop humming? A: Using balanced power can help solve certain ground loop problems because it takes its ground from one source, thus having no potential difference. You can do this yourself simply by taking all your power from one outlet or circuit. If your equipment “leaks” to the ground, meaning current is flowing to the ground wire, then balanced power might be helpful. Some people believe that… View this post

    Provided by Sweetwater.   Q: I’ve seen several tips and articles here on ProSoundWeb recently about batteries. I know batteries are expensive, which is something my church is confronted with regularly. Something I’ve been wondering is if people go to such trouble to store batteries on the fridge to make them last, obviously they have the discipline to use rechargeable batteries. So, are rechargeable batteries acceptable for live use? What do I need to know? A: Great question! The short… View this post

    THAT Corporation’s Chief Technology Officer, Gary Hebert, aims to unlock the secrets of designing cost effective, high-performance microphone preamplifiers at a tutorial during the 129th Audio Engineering Society Convention in San Francisco. Mr. Hebert’s tutorial, “Designing Microphone Preamplifiers”, addresses many of the challenges faced in this critical, largely analog part of the audio signal chain. Hebert will present a sampling of amplifier topologies and circuit details, and discuss design tradeoffs among cost, size, power consumption, noise, distortion, and other factors.… View this post

    Provided by Sweetwater.   Q: I just finished building my project, complete with some swanky dimmable lighting, and I’m all set to start mixing. However, there’s a buzz in my signal chain I just can’t chase down. Any advice? A: Anyone who has ever played a gig at the hotel ballroom has probably fought this battle at one time or another, but it’s really frustrating when it happens in your own studio. There are several problems that cause this, and… View this post

    power amplifiers
    Steve Lyle 10/15/10 03:44 PM,
    A power amplifier is a device for making a larger, more powerful signal out of a small, weak signal. It was on February 18, 1908 that Lee DeForest was granted U.S. Patent No. 879,532 titled “space telegraphy,” but in actuality, the patent was for a vacuum tube triode amplifier that DeForest called the “audion amplifier.” For the first time it was possible to amplify signals. The first amps were developed to support radio. Later, other applications were developed. All electronics… View this post

    Provided by Sweetwater.   Q: I’ve been working on designing my own mix room for quite a while. Is it a good idea to have a 220v outlet providing power to your home studio? Or, is there an easier way of providing good power using several 120v outlets and a distribution scheme? Will using 220v power help eliminate studio hums? A: There’s no real advantage to 220v power other than it generally can deliver more power in high demand applications… View this post

    Keith Clark 10/15/10 06:31 AM,
    The classic definitions of a wide range of facilities are now being altered dramatically, thanks in large part to the development, and deployment, of constantly improving multimedia technologies. Case in point: The Herrick District Library, located in Holland, Michigan. It had long fit the time-honored role of what we’ve all come to think of with mention of the term “library” - that is, stacks and rows of books, along with healthy doses of periodicals and reference materials. However, an impressive… View this post
