Tim Vear 12/12/11 03:30 PM,An important consideration in microphone use is acoustic interference, which can occur whenever delayed versions of the same sound are mixed together, acoustically or electrically. With mics, this may happen in several ways: mics of reverse polarity picking up the same sound, multiple mics picking up the same sound from different distances, a single mic picking up multiple reflections of the same sound, or any combination of these. The results are similar in each case, and include audible peaks and… View this story

Chuck McGregor 03/15/11 02:55 PM, 0 CommentsPolarity and Phase - two terms are often used as if they mean the same thing. They are not. POLARITY: In electricity this is a simple reversal of the plus and minus voltage. It doesn’t matter whether it is DC or AC voltage. For DC, Turn a battery around in a flashlight and you have inverted or, more commonly stated, reversed the polarity of the voltage going to the light bulb. For AC, interchange the two wires at the input… View this story

Mike Sokol 12/23/10 09:30 AM, 0 CommentsProvided by HOW To Church Sound Workshops. Few things can affect the quality of a sound as speakers being out of polarity. You can lose bass response, cancel your vocals and cause general phase mayhem in your sound system. There are may ways to determine polarity, however here’s a cheap and easy solution to test for proper wiring inside your speaker cabinets before you install them up on the wall and without running any audio signal through them. See… View this story

Barry Rudolph 11/19/10 02:40 PM, 0 CommentsFor recording electric guitars, I’ve been using a “trick” lately with the figure-of-eight Royer R121 ribbon microphone. I like this method because it increases the “coupling” of the low-end frequencies and air of the speakers to the mic, and I also find it great for loud clean sounds and cruncher rhythm parts, especially low-tuned guitar parts where you want as much “sturm und drang” as possible. I line up dual 4 x 12 Marshall cabinets directly facing each other as… View this story

Al Keltz 09/23/10 11:52 AM, 1 CommentUnbalanced 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

Bennett Prescott 08/12/09 04:56 PM, 1 CommentI’ve been trying to get my ugly mitts on a Soundcraft Vi6 since I first saw one at AES two years ago. Tom Der had one to spare this summer and shipped it down to Asbury Park, NJ where Jason Dermer’s company, TSL, will be putting it through its paces. Since I do a lot of work with Jason, I got assigned the duty of figuring out how the brightly lit control surface works, getting it set up, mixing the… View this story

PSW Staff 05/22/09 10:42 AM, 0 CommentsAt the upcoming 2009 InfoComm show in Orlando, Ashly Audio is introducing two new loudspeaker processors to its line of Protea DSP products. The Protea 4.8SP four-input/eight-output and Protea 3.6SP three-input/six-output 1RU digital signal processors offer an extremely intuitive user interface, plus PC control software, and comprehensive DSP, including crossover, equalization, delay and limiter functions. Gain, delay and six filters (each a choice of parametric, low- or high-shelf) may be applied to every input, each of which employs 24-bit, 48… View this story
