The Buzz: 20 Years Ago in Sound & Video Contractor

Feb 1, 2005 12:00 PM, By Mark Johnson

February 1985 was one of the largest issues to date. In the cover article “It's Not Easy Being Green,” Marge Gustafson, Chet Heyberger, and Larry Johnson, all from the portable oscilloscope division of Tektronix, offered basic instruction along with some tips on using an oscilloscope.

Many people call EPCOT EPCOT. But who knows that it stands for Experimental Prototype Community of Tomorrow? Martin Collins did and he took us through “The Electronics of EPCOT” in a look at the technology and devices employed in the themed environment. Billed at the time as the “largest permanent audio system installed in the United States,” the system incorporated 1200 soundtracks, 3200 processing channels, 3250 power amps with more than 250,000W of amplifier power, and more than 15,000 loudspeakers. Ok, I'd say that's still pretty big today.

A preview of the 1985 NSCA Expo included an overview of the workshops and seminars being offered at the show, as well as a listing of the exhibitors. In his editorial, Fred Ampel stressed the need to attend the expo and questioned those choosing not to attend.

In “2000 Years of Acoustics” by Jesse Klapholz, Klapholz highlights some noteworthy achievements and contributions in the world of acoustics. Klapholz was a frequent contributor to Sound & Video Contractor.

Allan R. Carlson brought us “Stadium Sound,” in which he examined some of the logistical and acoustical challenges faced when designing and installing large-scale systems for indoor and outdoor stadiums, including case studies of Soldier Field in Chicago; Zuppke Field at the University of Illinois, Champaign; Milwaukee County Stadium, Wisconsin; and the Hoosier Dome in Indianapolis. At the time, Carlson was vice president of design and production for Ancha Electronics, founded in 1964 and acquired by PRG in 1999. In 2000, SPL spun off of PRG with Ancha merging into SPL. Whew!

Dbx showed off its “Industry standards,” including the Dbx 160X, and 165 compressors, as well as the modular 900 series and the 700 digital audio processor.

Bose product development engineer Ken Jacobs provided a technology profile on the Bose 102 loudspeaker system. A sidebar defining active equalization and highlighting some of the benefits were included.

“The 2-Cocktail Convention: The Etiquette of Tax Deduction” by Penny Sirna Wiegand was a bit of business information offered up prior to the NSCA Expo. Frequent contributor P. John Brunstetter advised on “Effective Performance Appraisals.”

Chris Michie contributed a piece on installation of a Meyer Sound MSL-10 system as “A Single-Source Loudspeaker” for the Oakland Alameda County Coliseum. At the time, Michie was a technical writer for Meyer Sound. Through the years he also served as a technical editor for Mix, as well as contributing to the pages of Sound & Video Contractor.
