Differences, Cause & Effect And Consequences Of Polarity And Phase
Chuck McGregor 04/25/12 02:55 PM,Polarity and Phase - these 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 post

Friday, April 13, 2012Why Not Wye? When Combining Two Signals Into One Is Not A Good Idea
Dennis A. Bohn 04/13/12 01:34 PM,This article is provided by Rane Corporation. Wye-connectors (or “Y”-connectors, if you prefer) should never have been created. Anything that can be hooked-up wrong, will be. You-know-who said that, and she was right. A wye-connector used to split a signal into two lines is being used properly; a wye-connector used to mix two signals into one is being abused and may even damage the equipment involved. Here is the rule: Outputs are low impedance and must only be connected… View this post

In The Studio: Techniques For Double Tracking Guitars
Jon Tidey 04/12/12 10:56 AM,This article is provided by Audio Geek Zine. Double tracking is a very common recording/production technique for almost any genre of music. When it comes to rhythm guitars, this technique is almost a standard method of recording with single tracking used only for solos. It’s also a technique that is often confusing for beginners. Double tracking simply means recording the same part twice and panning each to opposite sides. The guitarist plays a section of the song perfectly, then… View this post

Wednesday, April 11, 2012Predicting Array Performance: Hanging The PA Right The First Time
Bruce Main 04/11/12 05:47 PM,Back in the good old days predicting the performance of a group of loudspeakers was a hit and miss proposition. We tried to hit all the people and miss the walls. We were happy if we had enough devices to point a transducer everywhere that needed coverage and enough power to make it good and loud. Complex interactions between devices operating in the same bandwidth, fine level adjustments for individual devices and precise flying angles were the least of our… View this post

Sound Wave Propagation: The Bigger Picture Of What We Hear
Neil Thompson Shade 04/11/12 09:14 AM,Previously (here and here), we’ve been looking at sound on a “microscopic” level, examining particle motion as sound propagates through air. This time, let’s look at a larger picture of sound wave propagation. A vibrating object will disturb the surrounding air medium causing localized changes in pressure and particle displacement with the transference of acoustical energy in the form of a sound wave. Waves can be broadly classified as being either transverse or longitudinal. The distinction for each wave type… View this post

Thursday, April 05, 2012Science Or Snake Oil? The Facts Behind The Hype About Loudspeaker Wire
John Roberts 04/05/12 02:46 PM,Too many good folks have been separated from their hard earned money by hyperbolic claims about loudspeaker wire. There will always be people with more dollars than sense, but they don’t last very long in professional audio. I speculate there aren’t many (if any) of you who would pay thousands, or even tens of dollars per foot for speaker wire. A very basic practice in merchandising is called differentiation. Marketers must come up with reasons for why you should buy… View this post
