Wednesday, December 01, 2010Limiters Unlimited: Properly Protecting Your System
Monty Ross 12/01/10 03:07 PM, 0 CommentsLimiters are in the protection business, limiting audio systems to safe levels. These limits protect loudspeakers, protect the audio signal from clipping, protect the neighbors, and protect ears. A limiter continuously monitors the audio signal, looking for levels exceeding its adjustable threshold. A limiter normally operates at unity gain and has no effect on the signal. If excessive levels are detected, the Voltage Controlled Attenuator (VCA) automatically reduces the gain. If the level never exceeds the threshold, the signal remains… View this post

Acoustic Treatment vs. Digital Room Correction
Joe Gilder 12/01/10 02:02 PM,This article is provided by Home Studio Corner. Some time ago I had the pleasure of attending a seminar given by Gavin Haverstick of Auralex Acoustics. The topic of the seminar was how to measure the acoustic issues of your room. He talked about various measurement techniques and devices. All of this was very interesting, but the most fascinating part for me was during the question-and-answer section at the end. Someone in the audience asked Gavin to give his… View this post

Can I Get a Rim Shot? Working with Electronic Drums
Chris Huff 12/01/10 10:02 AM, 0 CommentsThis article is provided by Behind The Mixer. Alone on the stage sits your new electronic drum set. No cage around it. No elaborate microphone setup. It’s perfect for your church! It might be an easier setup than an acoustic drum kit but despite their advantages, electronic drums come with their own set of frustrations Some Of The Downsides • One audio send to rule them all. Many of the lower-priced models only send one audio signal out so… View this post

Tuesday, November 30, 2010The Nuances Of Crest Factor
Pat Brown 11/30/10 02:10 PM, 0 CommentsThe crest factor of an audio signal is the dB difference between the peaks and the RMS value of the signal. The RMS (Root Mean Square) is defined as the “heating value” of the signal - the voltage that would generate the same heat as a DC (Direct Current) signal, over the same time. The RMS value of a complex signal must be read with an RMS voltmeter. Alternatively, the signal can be digitally sampled and the samples summed to… View this post

The Mighty High Pass Filter: Are You Well Acquainted With This Essential Mixing Tool?
Mike Sessler 11/30/10 09:32 AM, 3 CommentsThis article is provided by ChurchTechArts. I was watching something on TV the other day and after hearing multiple “plosives” (P’s and B’s and T’s) just booming away through my speakers, I quipped, “Can we please get a high pass on that mic!” Then I realized there still may be a number of young sound guys/gals (YSG’s) out there who are not yet acquainted with the high pass filter (HPF). Allow me to make the introduction. The high pass… View this post

Monday, November 29, 2010Distortion & Noise: What You Need To Understand When Recording
Jason Corey 11/29/10 03:40 PM, 0 CommentsThis excerpt provided by Focal Press In the recording process, engineers regularly encounter technical issues that cause noises to be introduced or audio signals to be degraded inadvertently. To the careful listener, such events remove the illusion of transparent audio technology, revealing a recorded musical performance and reminding them that they are listening to a recording mediated by once invisible but now clearly apparent technology. It becomes more difficult for a listener to completely enjoy any artistic statement when… View this post

Church Sound Basics: Test Your Cables On A Regular Basis To Ensure Reliable System Performance
Gary Zandstra 11/29/10 10:04 AM, 1 CommentOperating 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 post

Tuesday, November 23, 2010The Holidays Are Approaching - What If You Run Out Of Inputs?
Mike Sessler 11/23/10 10:30 AM, 0 CommentsThis article is provided by ChurchTechArts. As Christmas Season approaches, I’m sure many of you are planning for your big Christmas services or productions. It’s going to be an extremely involved production here at Coast Hills and I woke up in a cold sweat the other morning realizing I had forgotten two mics and didn’t have the inputs for them. As I plotted out my strategy to free up inputs where there seemed to be none, it occurred to… View this post

Friday, November 19, 2010Barry’s Recording Tips: Figure Of Eight Royer For Electric Guitars
Barry Rudolph 11/19/10 01:40 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 post
