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…

This is the 40th anniversary of Altec Lansing’s passive third-octave “continuous” equalizer that began modern sound system equalization. It didn’t start as a graphic equalizer, but rather, was three rows of eight knobs on third octave centers. A companion third-octave real-time analyzer, three rows of eight VU meters, provided a means to measure a sound system. Subsequent Altec EQs replaced the knobs with a row of sliders, earning the name “graphic” because their positions provide a graphic display of the…

As with all sizes of modular line array enclosures there are several designs in the “mini” genre, which we define as those with 7-inch “woofers”. The simplest two-way systems have a single cone driver and a high-frequency driver, side by each. Some employ dual woofers, and those with a center high-frequency section that provides horizontal symmetry. Quasi-three-way solutions use dual woofers, but cross one over earlier, so the other is the single source of mid-range, eliminating cancellations. True three-way designs…

Aviom, known to countless church sound personnel and musicians for its “more of me” personal monitor mixing controls, has put considerable work into how to move audio signals from one place to another. It’s led to the development of a digital snake system and audio networking system, which Kent Gibson discusses in the August, 2009 issue of Church Production magazine. How does this technology work? What are the advantages (and potential downsides) of transporting signal in the digital domain? And…
