Bob McCarthy 12/19/11 09:07 AM,“I am going to equalize the room.” We’ve all heard that statement so many times that we scarcely think about what it literally means. We know that in practical terms it means adjusting an equalizer to suit your taste. It may be done with the latest high-technology analysis equipment, voodoo magic or simply tweaking away “until it sounds right.” In any case, are we really “equalizing the room”? What exactly are we doing? There are lots of disagreements on this… View this story

PSW Staff 12/19/11 08:52 AM, 0 CommentsThe new version of the Rational Acoustics branded RTA-420 is a budget-friendly measurement microphone with an impressively flat response curve for its price, and as a result, it works well as a “starter” mic, a spare, or a “B” rig mic for use in tough conditions where the user might not want to deploy a more expensive mic. The RTA-420 offers heavy-gauge steel construction and measurement performance similar to high-end mics costing many times more. It is supplied with a… View this story

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

PSW Staff 12/06/11 01:38 PM, 0 CommentsiSEMcon has introduced the EMX-7150, a 1/4-inch measurement microphone that has a 10Hz to 20 kHz, IEC61672 class frequency response, designed for room and recording studio analysis, as well as indoor and open-air sound reinforcement measurements. The EMX-7150 is an omnidirectional type microphone and the first to include the free field and derived diffuse field calibration data at no additional cost (calibration chart and ASCII-Data on CD). It can be powered with phantom power and handles sound pressure levels up… View this story

PSW Staff 12/01/11 12:05 PM, 0 CommentsAudix has introduced the TM1 Plus, a combination kit that includes the TM1 measurement microphone, threaded acoustic windscreen, shock mount clip, 1/2-inch calibrator adapter and microphone calibration data on CD. The data files are a numeric representation of the TM1 frequency response. Together with the provided sensitivity of the microphone, they can be used with a variety of popular software measurement systems to correct the response curve of the microphone. “The TM1 has earned very high acceptance among sound engineers… View this story

Pat Brown 10/11/11 06:07 PM, 0 CommentsSite surveys are a necessary part of all construction trades. The ground must be firm enough to support the building. The water must drain properly. There must be adequate ingress and egress. The list goes on. Sound system designers should also perform a site survey of the auditorium to determine the conditions in which the new sound system must operate. There are a multitude of parameters that can be measured in a building, but it won’t be possible, practical or… View this story

Pat Brown 09/22/11 06:28 PM, 0 CommentsHere’s a simple way to construct an irrefutable polarity test rig to check out your measurement system: 1) Get two small cone transducers to use as a reference – the simpler the better. 2) Momentarily connect a 9V battery (+ to + and – to -) to each loudspeaker. 3) The loudspeaker cones should move away from the magnet. 4) Check all of your measurement audio interconnect cables for proper polarity with a cable tester. I use simple twisted pair… View this story

Pat Brown 09/15/11 10:42 AM, 2 CommentsI’ve done enough theorizing and musing about power and power ratings in parts 1 and 2 of this series. (Read part 1 here and part 2 here.) Let’s convert some utility power into audio power. First, some details about the testing. The Source, The Load “Source” and “load” are usually associated with amplifier and loudspeaker. I had to zoom out another level and consider the AC source to the amplifier (these amplifiers need a lot of juice). The amplifier has… View this story

Gary Zandstra 09/12/11 04:04 PM,It seems like every week I end up in a conversation about volume levels and that “so and so” thinks it’s too loud. A while back I discussed the more technical side of sound level, but today, let’s focus on perception. In the space where I mix or act as producer almost every Sunday, we hold two very distinct services. The early service is more “traditional” (whatever that means) with brass, strings, organ, choir, and a worship team of vocalists.… View this story
