Gary Zandstra 07/30/12 12:12 PM,Operating the sound system from the mix position during a recent Sunday worship service, it all began when the first note from our grand piano was distorted. Hmm… We’d checked the piano channel and sound prior to the service, and all was fine. My first reaction to the distortion being produced was to reduce the gain on that console channel, thinking perhaps the piano player was nailing the keys very hard. Yet the problem remained. Next, I did a pre-fade… View this story

Rob Stam 06/11/12 12:31 PM,In my many encounters with church building committees over the years, there’s often an overwhelming theme: build a room that can be utilized for a multitude of functions including worship, theatrical productions, concerts, special events, dinners, receptions… the list goes on. It’s a discussion of compromise and of thinking to the future. For example, wouldn’t it have been nice - 25 years ago - if the building committee had considered that there might be need of more than a “roamer… View this story

Paul LaPlaca 06/08/12 07:44 AM,Very early in my career, I worked in the field as a sound recordist for WNED, a television station in Buffalo, New York. My first day on the job, we finished doing a video shoot, and being the low person on the depth chart, it fell to me to pack up and put things away. Never to be forgotten were the gasps of true horror as I proudly grabbed an XLR cable by its end with one hand and began… View this story

Josh Thompson 05/22/12 01:49 PM,Sooner or later, regardless of our chosen path in pro audio, the worst happens: someone asks us to install a system. Even if our preferred gig involves a Prevost and chain motors, folks tend to assume that “sound is sound,” and if you are a professional in one area, you are surely qualified in all others. Even with no real hands-on install experience, most of us have no problem signing up for the occasional install gig. The gear looks the… View this story

Al Keltz 04/05/12 02:42 PM,Unbalanced Lines Unbalanced signal lines are characterized by the fact that the cable and connectors use only two conductors, a center conductor surrounded by a shield. Examples of unbalanced wiring are found in tip/sleeve 1/4-in guitar cords or the cables used with many CD players and tape decks which terminate with RCA phono type connectors. In an unbalanced configuration, the shield surrounds a single center conductor. The shield stays at a constant ground potential (as it is connected to ground… View this story

Bill Whitlock 03/21/12 06:33 PM,Based on my years of helping customers solve interfacing problems of all sorts, connecting unbalanced outputs to balanced inputs, and vice-versa, certainly ranks among the most common and confusing of tasks for system integrators. Basically, two issues must be dealt with. The first involves the different signal operating levels between unbalanced (consumer) and balanced (professional) equipment. The second involves making the actual connections to transfer the signal while avoiding “ground loop” noise problems. Signal operating and reference levels are significantly… View this story

Buddy Oliver 02/23/12 03:46 PM,An easy way to understand how fiber optics works: visualize peering into a very long tube, the inside of which is coated with a perfectly mirrored surface. One mile away, at the opposite end, a friend shines a bright flashlight into the tube. Because the tube is internally coated with a perfect mirror, you will see his light perfectly at your end, regardless of how many twists and turns the pipe takes. If your friend flashes the light off and… View this story

John Lopinto 10/28/11 03:11 PM,With the increasing trend toward the use of fiber instead of co-ax cable in a wide range of applications, most contractors are now required to understand the basics of terminating and laying fiber optic cable. Contrary to its reputation, fiber is actually quite easy to handle and use. Cable Construction Fiber, at its most basic level, is a very pure strand of glass through which light can pass over great distances. All fiber optic cable has at its center a… View this story

Chris Bushick 06/29/11 04:45 PM,As with many types of cable, you can save some money by purchasing Ethernet cable and connectors and assembling/terminating them yourself. Of course, keep in mind that putting together cables of any type requires time, patience and some know-how. Without these essential ingredients, you’ll be much better served by buying pre-terminated cables. That said, let’s get started. First, to attach any Ethernet RJ-45 connector ends to the lengths of cable, you’ll need an RJ-45 crimping tool. Start with a good… View this story

Al Keltz 06/29/11 01:40 PM, 0 CommentsIf church sound system has evolved along a familiar path, what started out as a pretty simple, small group, “sound-on-a-stick” has gradually become more and more sophisticated. Many have replaced that powered mixer with separate components and added a snake to allow for a mix position in the listening area. Words like “direct box”, “balanced”, “low impedance”, “crossover”, etc. have become part of the sound team’s vocabulary as they strive to provide today’s expected level of sound quality and production… View this story
