Twenty years ago the lead off article was “Electronic Imaging” by Gary W. Hughes, which, except for a couple of audio-related articles, pretty much set the tone for the issue. Hughes' article discussed the impact that CCD imagers had on video camera technology since their invention in 1970. Hughes was responsible for CCD imagers and systems research at RCA Laboratories.

Richard C. Cabot contributed “Crossover Systems” — one of the two audio-themed articles. Cabot, principal designer with Audio Precision in 1985, examined the various crossover types and their functions. Now Cabot heads XFRM, an intellectual property development company formed to create and develop new ideas and technologies in a variety of technical areas, primarily high-quality audio- and digital-signal processing. The other audio-themed article was Terry Pennington's “Perfecting Alignment.” In the article, Pennington discussed Linkwitz-Riley's alignment technology and its advantages and applications. At the time, Pennington was national sales manager for Rane Corporation. Currently, he remains with Rane as MIS manager.

Back to the visual theme, Sound & Video Contractor's staff provided “CCTV Surveillance.” This installation profile described how a CCTV system was adapted to serve three different functions.

Exxon's Research and Engineering facility in Clinton N.J. was the subject of another installation profile, “CCTV Placement,” by Barry Levine. The article featured specific challenges faced in determining appropriate products, and then installing and getting them to work properly. Levine was president of Sperry-Vision, a security consulting company.

“CCD Technology,” by Kunio Sano, then a camera products manager for Sony's communication products division, took a look at the application of CCD technology and its products.

Neil R. Heller explored “Time-lapse VTRs” with a discussion of the diversity of applications for time-lapse recording and how to best adapt a system. Heller was a video security consultant in Diamond Bar, Calif.

Stan Kohagen, who was with Aiphone Intercom Systems, provided application information for video intercom systems in “Somebody's Watching You.” Kohagen was a frequent contributor to Sound & Video Contractor.

In business news, the venerable Shure Brothers celebrated its 60th anniversary on April 25, 1985. That makes it 80 this year! TOA Electronics was celebrating two anniversaries; its 50th in Japan and it's 10th in the United States. TOA celebrated by restructuring its U.S. corporate divisions and remodeling its San Francisco headquarters. Those party animals. …

Reproduction of the midrange frequencies (400Hz to 3500kHz) was the topic of discussion in David Scheirman's column “Reinforced Audio.” In it he discussed the importance of the mid frequencies and how speaker systems dealt with them. Also included was an overview of how four companies — Community Light & Sound, Emilar, Renkus-Heinz, and Turbosound — applied their technologies for midrange reproduction.

Aiphone ran an ad on the inside front cover promoting its intercom systems and accessories. Aiphone continues to thrive in the area of video and audio door answering intercom systems for security applications. Its U.S. headquarters is still at the same address in Bellevue, Wash., as it was 20 years ago. Panasonic touted its 1410 series of Vidicon and Newvicon cameras for security applications. Crown International introduced the PCC-160 boundary microphone. This mic, pretty much an industry standard, is included in Crown's current lineup of microphone offerings. AMX urged us to “Take Control” with its wireless and Softwire remote control systems.

In people news, Bogen Division, Lear Siegler appointed Carl C. Dorwaldt vice president, marketing, and Andrew M. Musci sales engineer, Engineered Sound Systems. Currently, Dorwaldt is marketing manager for Renkus-Heinz and Musci is the president of Altel Systems in Brewster, N.Y. Musci also serves on the NSCA board of directors as secretary/treasurer.
