05/04/11 10:18 AM, 0 CommentsMicrophone techniques (the selection and placement of microphones) have a major influence on the audio quality of a sound reinforcement system. In order to provide some background for these techniques it is useful first to understand some of the important characteristics of the microphones themselves. The most important characteristics of microphones for live sound applications are their operating principle, frequency response and directionality. Secondary characteristics are their electrical output and actual physical design. Operating Principle The type of transducer inside… View this story

Shure Incorporated 04/22/11 11:08 AM, 1 CommentEvery time the number of open or active microphones in your church system increases, the system gain (or volume) also increases. The effect of this is greater potential for feedback as more microphones are added, just as if the master volume control were being turned up. In addition, unwanted background noise increases with the number of open microphones. Here, the effect is a loss of intelligibility as the background noise level rises closer to the level of the desired sound.… View this story

Bruce Bartlett 04/04/11 07:25 AM,What goes around comes around. From the 1920s through the 1940s, PA systems for music often used only a single microphone. Band members would gather closely around this mic, balancing their sound by moving toward or away from the mic. Radio broadcasts and recordings often used one mic as well. This “old fashioned” technique has made a comeback; for example, many bluegrass and folk bands utilize the one-mic method with surprisingly good result, typically using a large diaphragm cardioid condenser.… View this story

Tim Vear 03/30/11 10:03 AM, 0 CommentsMicrophone positioning and technique is largely a matter or personal tastes - usually whatever “sounds right” probably is right. Nevertheless it’s a good idea to remind ourselves of some of the basics for getting there. Following are a few tips that you might consider following when micing musical instruments for sound reinforcement. • Try first to get the instrument to sound good acoustically before miking it. • Use a mic with a frequency response that is limited to the frequency… View this story

Bruce Bartlett 03/25/11 01:54 PM, 0 CommentsThis article is provided by Bartlett Microphones. Condenser microphones need phantom power to operate their internal circuitry. This article explains phantom powering, tells how to use it, and offers some precautions for its use. Phantom power is supplied to the mic through its 2-conductor shielded cable. The power can be supplied either from a stand-alone device or from a mixing console (at each mic connector). The microphone receives power from, and sends audio to, the mixer along the same… View this story

Peter Franco 03/25/11 01:00 PM, 0 CommentsHere’s a look at the way I use microphones on acoustic guitar, electric guitar, upright bass guitar, electric bass guitar, horns and vocals. Keep in mind that this is the way I mic these instruments - you should not take it as the “right and only way”. Experiment, listen carefully and try to find “cool sounds” on your own. Let’s begin with the acoustic guitar. Almost every acoustic guitarist I’ve worked with has had an internal pickup built into his… View this story

Patrick Morvlyth 03/24/11 12:00 PM, 0 CommentsThere is a problem within the British milk industry. Fifty years ago, most milk was sold at the doorstep, and though in big cities it might be the province of the large conglomerate dairies, in the majority of towns and villages, smaller enterprises held sway. Many of these were run by groups of farmers who owned the entire production and delivery chain from grass field to milk van. Much of this milk was of exceptional quality. Shelf life was not… View this story

PSW Staff 03/16/11 04:18 PM,What is impedance? Impedance is the AC (alternating current) version of the DC (direct current) term resistance, which is the opposition to electron current flow in a circuit and is expressed in ohms. Impedance (often abbreviated as “Z”) includes capactive reactance and inductive reactance in addition to simple DC resistance. Reactance depends upon the frequency of the signal flowing in the circuit. Capactive reactance increases as frequency decreases: inductive reactance increases as frequency increases. Because of this frequency dependence, impedance… View this story

Barry Rudolph 03/11/11 05:02 PM, 2 CommentsBecause of its fundamental importance in popular music, the electric guitar is the subject of intense scrutiny and wide differences of opinions. Just what makes a good guitar sound? Compared to all the subtle and not so subtle sounds that come out of an electric guitar amp, fidelity judgments of vocal sounds are easy to make! With good knowledge of the different guitar and amplifier sonic capabilities, coupled with good microphone techniques,we can achieve the ultimate guitar sound that “fits”… View this story

Mike Sessler 02/22/11 01:35 PM, 1 CommentThis article is provided by ChurchTechArts. An important yet often misunderstood characteristic of directional microphones is Proximity Effect. The proximity effect is one that exists in microphones with any of the cardioid (cardioid, super-cardioid, hyper-cardioid, ultra-intersellar-cardoid—OK, I made that last one up…) patterns. As the mic is moved closer to the sound source, the low end response of the mic is boosted. On this graph, the solid line represents the response of the mic at 12” from the sound… View this story
