Sign Off By Kari Taylor, associate editor May 1, 2004 12:00 PM Do you remember? In 1981 Applied Technology offered two audio processors with digital control capabilities.
The Maximod digital peak limiter used a digital processor for peak limiting control. It was designed to enhance the overall loudness of the sound, or to clean up the audio. The Discriminate Audio Processor III offered multiband leveling. Settings for the crossover, compression, attack and release were variable. Radio magazine is looking for more information regarding these products. If you have additional information, please send it to ktaylor@primediabusiness.com. Note: These products are not connected to Dorrough Electronics. We already tried that. That was then
In this 1947 photo, Jack Mullin (left) shows Murdo MacKenzie, Bing Crosby's technical producer, how to edit tape using a pair of scissors. The equipment shown in the photo is the Ampex model 200 prototype. In 1945, Mullin had sent two German AEG Magnetophons and 50 reels of BASF/Agfa tape home to San Francisco, where he modified them with ac bias as well as made other improvements. Mullin's Magnetophons later inspired that first Ampex machine. It all began when Mullin was stationed in England during WWII. Then-Lieutenant Mullin was assigned to help improve the performance of Allied radar and other electronics, working mainly on solving a series of radio-frequency interference problems. In January of 1946, the electrical engineer entered into a business partnership with filmmaker W. A. (Bill) Palmer, a pioneer of 16 mm sound-film, who provided financial and mechanical engineering assistance for their project: to greatly improve Magnetophon performance. Bing Crosby's technical producer, Murdo MacKenzie, heard about the Mullin-Palmer machines from two of Bing's agents and arranged for the singer, his manager-brother Everett Crosby, and the rest of Bing's organization to hear the recording breakthrough.
