    impedance
    Jonah Altrove 10/06/16 08:42 AM,
    It may not seem so at first blush, but there are a few concepts as pervasive in live audio as the concept of impedance. It’s relevant to microphones, direct boxes (DIs), preamps, processors, amplifiers, loudspeakers, equalizers, crossover filters, and even the cables that connect them all together. In this article we’ll explore the principles of impedance, and examine how these concepts apply directly to our work in the field.

    Chapter 5 of PSW’s ongoing free white paper series in now available. (Get it here.) The new installment, entitled “Understanding Impedance In Audio Transformers,” brings clarity to the issue of impedance, and explains how transformers are of special interest because they are capable of transforming impedances, while also providing galvanic isolation and many additional benefits. The white paper series is presented by Lundahl, a world leader in the design and production of transformers, and is authored by Ken DeLoria, senior… View this story

    This article is provided by Rane Corporation. What could be more mundane than the transformers and autoformers that are the backbone of audio distribution systems? This article will show you that there is a lot more going on with these chunks of iron and copper than you ever suspected. Learn why transformers are often the power bottleneck in distribution systems, learn how to interpret datasheets, believe or disbelieve manufacturers’ claims, how to specify HV components, and how to set up… View this story

    tech topic impedance
    Pat Brown 08/09/12 01:11 PM,
    A common task in “audioland” is the need to feed a number of inputs from a single signal source. This may include driving a rack of amplifiers, providing feeds to the press, or distributing a signal around a building or campus. The methods used to accomplish this range from the profoundly simple to quite complex, and the appropriate method can only be determined after sizing up the situation. Impedance matching means that an output is terminated with a “mirror” input… View this story

    impedance
    Pat Brown 05/20/11 06:31 AM, 0 Comments
    Because the impedance of a loudspeaker is a frequency-dependent parameter, it must be measured at multiple frequencies to get a true picture of what the amplifier is “seeing” at its output terminals. While very sophisticated methods and instruments exist, you can get a pretty good idea about the impedance curve of a loudspeaker with a standard real-time analyzer. You will need a pink noise generator and voltage source of at least 10 volts RMS to drive the loudspeaker. A small… View this story

    Front of House Engineer Kyle Chirnside is utilizing a Midas PRO6 digital console on the current world tour by Fall Out Boy. “I’ve always been a Midas guy,” states Chirnside. “Whenever I had a choice, I would have my XL4. But then I had the chance to test drive the XL8.” That opportunity came with an invitation visit Metallica FOH Engineer Big Mick Hughes during preparations for Fall Out Boy’s autumn 2008 tour of the UK and Europe. “We were… View this story

    BAE (Brent Averill Enterprises) has introduced the new, improved 1272 and 1272A stereo mic preamplifiers, featuring a new twist on vintage design, with the hand-built units now housed in enclosed chassis. “The benefit of this new design is that it provides more real estate on which to place additional features,” commented BAE President, Mark Loughman. “The four buttons on the faceplate signify 48-volt phantom power, phase reverse, direct line input and selectable mic input impedance of 1200 and 300 ohms.”… View this story

    Sennheiser has long been one of the top wireless system manufacturers, respected for solid technology, high audio quality and a wide range of products, all evidenced by a long and varied user list. Earlier this year at the NAB (National Association of Broadcasters) show in Las Vegas, Sennheiser introduced the 2000 Series, its latest wireless system development. Pricing of the new 2000 Series is in line with the Shure UHF-R Series, and it now represents the “middle” of the Sennheiser… View this story
