Originally posted in the April 1977 issue of Recording Engineer/Producer (RE/P). Abadon/Sun Studio was located in San Antonio, TX. By Woody Smith & Galen Carol We at Abadon/Sun decided to write this article because we felt a large number of small studio owners required more information to properly design and build their first studio. What we’ve tried to do is to simplify things as much as possible and provide the builder with the design fundamentals. Since most small control rooms are rectangular in shape we’ll detail the design considerations for a room of that shape. Our primary goal is...Read More

by John Eargle James Bullough Lansing was born James Martini, 14 January 1902, in Macoupin County, Millwood Township, Illinois. His parents were Henry Martini, born in St. Louis, Missouri, and Grace Erbs Martini, born in Central City, Illinois. The elder Martini was a coal mining engineer, and his work required that the family moved about quite a bit during Lansing’s early years. Lansing was the ninth of fourteen children, one of whom died in infancy. For a short time, Lansing lived with the Bullough family in Litchfield, Illinois. He later took their name when he changed his from Martini...Read More
by Keith Clark Editor’s note: This interview was conducted in the early 2000s. When noting the contributions of Don and Carolyn Davis to the professional audio industry, it’s hard to know where to even start. Their book, Sound System Engineering, originally published in 1973 (and since updated), remains a standard audio and systems resource. Founders of SynAudCon, Don and Carolyn established the industry’s pre-imminent and most respected (and independent) educational resource, teaching thousands the essential concepts of audio and acoustics that in turn has led to remarkable advancements in systems and sound quality that we all enjoy. Now consider...Read More

By Keith Clark Editor’s Note: This article was written in the early 2000s. So just how does one neatly summarize the history of a company that’s contributed a steady stream of advancements that have helped form an industry over the course of more than 70 years? The answer comes largely from the people who have created the company’s story; in this case, Electro-Voice (EV), which on July 1 of this year marked its 71st anniversary. As part of my research for this project, I interviewed Jim Long, who’s been with EV for nearly 40 years. Many of you probably...Read More

by Frederick J. Ampel Using our Stephen Hawking approved design for a real time machine, we journey to the dawn of the last century. It’s the summer of 1905 and in under a year the mechanical age will give way to the dawning of the electrical age. At this time the world is dominated by giant machines that can truly be called “heavy iron.” Machines like this: These 200-plus-ton behemoths are the quintessential embodiment of the leading edge of engineering and technology, and have already dramatically changed the world by making it possible to go to far away destinations...Read More
