  1. Hello, I have a 35 year old Dolby 372 unit that needs some servicing. I contacted Dolby and unfortunately they do not service their older instruments anymore. Everything on the left channel works but the right channel has a shrill thinning sound when playing back a 320 wBn test, encode in record with NR on has no problem, however, playback "NR off" produces a distorted,/scratching sound. I feel like I have exhausted my options besides constant cleaning etc. Do any of you leaders have any advice for troubleshooting or suggestions of whom I could contact to inspect/repair this unit. I am using a Nagra X4S at 15ips with Stellavox AMI48 mixer. As always, any advice will be greatly appreciated. Thank you MarkC
  2. Back when the crackling of a record doubled as ambient noise, Ray Dolby conceived the unthinkable—that he could provide the public with crisp, clean sound. So, in the mid ’60s, he began work on a state-of-the-art noise-reduction system that would not only revolutionize tape and album recording, but also change the way we listen. Dolby, a Portland-born, Stanford-educated engineer, worked with Ampex Corporation on the world’s first videotape recorder throughout his collegiate career. He then enrolled at Cambridge University, where he earned a Ph.D. in physics, and briefly served as a technical advisor for the United Nations. But in 1965, he branched out on his own to launch Dolby Laboratories—and the Dolby Sound System was born. The Dolby A, a professional broadband noise reduction for recording studios, was the company’s first product. It reduced the amount of background noise and hissing often heard in professional tape recordings, without interfering with the original material. The machine accomplished this by separating the softer signals from the louder ones, and processing only the former. The Dolby B, a comparable version for consumers, was introduced in 1968. By this time, the film industry had taken notice of Dolby’s advancements and demand grew for quality sound in the world of movie production. A Clockwork Orange was the first film to use Dolby sound. A Clockwork Orange (1971) was the first film with Dolby sound, though it only incorporated the use of sound reduction. Over the next several years, several films such as Callan (1974) and A Star Is Born (1976) would incorporate other Dolby technologies. The 1977 box-office smashes Star Wars and Close Encounters of the Third Kind marked the first time that a film was released entirely in Dolby Stereo, providing audiences with true noise-reduction technology. This also signaled a change among smaller movie theaters across the country, which began installing stereo equipment for better audio quality. Star Wars was the first film to be released entirely in Dolby Stereo. As the film and music industry continued to evolve, so did Dolby’s technology—introducing Dolby Surround in 1982, improving analog recording in the mid ’80s, and elevating the home-cinema experience with four-channel sound. In 1991, Dolby Digital became the official sound format for films. Since then, Dolby has continued to provide innovations for everything from headphones to video games to the creation of Dolby 3D, Hollywood’s Dolby Theatre and 2012’s latest audio upgrade, Dolby Atmos—which is currently featured in 25 cinemas around the world. At 80 years old and with 50 patents to his credit, Ray Dolby has retired from his namesake business, but his imprint on quality sound innovation will undoubtedly be felt heard for years to come. The Kodak Theatre was officially renamed the Dolby Theatre May 1, 2012. Link: https://www.doyouremember.com/news/the-incredible-birth-of-dolby-sound
  3. I just saw a screening of “The Impossible,” an extraordinary film about the experiences of a family swept up in the 2004 Tsunami while vacationing in Thailand. Ewan McGregor and Naomi Watts play the parents and Tom Holland their eldest son, Lucas. I’ve not heard much about this film but viewing it was a riveting experience with excellent performances. It’s a 23.1 mix and the sound design is an important element in the experience. See it in a theater with a good audio system if you have the choice. David
