The Buzz: 20 Years Ago in
Sound & Video Contractor

The cover feature 20 years ago this month was “The Effects of AC Line Disturbances,” a piece contributed by Jerry Whitaker, who pulled double duty as Sound & Video Contractor's RF Technology editor and the editor of Broadcast Engineering at the time.
Ron Williamson contributed “DMMs Accessories and Features,” which provided some good information on how to use digital multimeters for electrical measurements and how to best accessorize your DMM for extended measurement capabilities. Williamson was a product specialist with the Service Products Business Unit, General Test and Service Division of John Fluke Manufacturing. Just try to fit that on a business card.
Bruce Olson provided an installation profile of the Ordway Music Theater and discussed the design process that took place to outfit the audio systems in the various venues throughout the facility. Olson was a systems consultant with AVC Systems (the audio and video contractor) in Minneapolis. Olson is currently principal consultant at Olson Sound Design (a company he founded in 1991) in Brooklyn Park, Minn.
Coming back around to line disturbances, “Surge Suppressor Applications” by Richard Goldstein explained how to apply surge suppressors to prevent the adverse affects of power line disturbances to electronic equipment. Goldstein was director of engineering for Perma-Power, Chicago.
Editor Frederick J. Ampel looked to the coming year in “Forecast '86,” a synopsis of developments and trends within the industry. Some of the markets where growth was anticipated were religious facilities and teleconferencing and video technologies.
A column by Barry Levine, president of Sperry-Vision and Sound & Video Contractor's CCTV security and design consultant, kicked off a new department, Security Close-up, this month. And another new department, Tech Tips, was also introduced in the December 1985 issue. Edward Simon of Edward Simon & Company tackled projector interface problems as his premiere topic. The column would consist of useful technical info and kit-type projects to help solve some of the common challenges contractors faced in the field.
Among the new products featured in What's New were three new equalizers: a new 1/3-octave, 27-band graphic EQ from Panasonic under its RAMSA brand; SCV Audio's model 213, a 13-band minimum phase, 2-channel unit; and Cetec Raymer's EQ-2, designed for high-impedance systems. Other new product announcements included Nakamichi's MR-2 two-head professional cassette deck and Kloss Video's VideoBeam VB2000 color projection monitor for large-screen display of computer graphics, alphanumeric data, and conventional video sources. The projector featured 640×480 resolution.
Reviewing some of the ads in the December '85 issue: TOA defined quality and featured its 900 Series of commercial sound and background music systems. Audio-Technica introduced its UniPoint cardioid Fixed-Charge condenser mics. A-T recently re-engineered the UniPoint line — look for a review of the re-tuned UniPoint series in the January 2006 Sound & Video Contractor. Bogen (a Lear Seigler company in 1985) promoted “Mixing Made To Order” with its HI-TEK Professional Series modular mixing system (the MMR-1) featuring a variety of input and output modules. Each frame accommodated up to 16 modules.
