Dolby Laboratories Inc. worked with The Recording Academy for the fifth year in a row to deliver a surround sound broadcast of the 49th Annual Grammy Awards on Sunday, February 11, 2007 on CBS and CBS HDTV. The worldwide broadcast featured live musical performances from the industry’s hottest artists and was broadcast in Dolby Digital 5.1 on HDTV, and Dolby Pro Logic II on analog channels.
“The Recording Academy sets out every year to establish new industry benchmarks for technical excellence at the Grammy Awards,” says Recording Academy President Neil Portnow. “Once again, we thank Dolby for its remarkable contribution to the high quality of our broadcast audio. Dolby’s support has been instrumental in achieving these superior results, especially during the last five years that we have offered high-def and surround sound on our Grammy Awards show production.”
Dolby supplied equipment for multiple mix rooms and provided on-site engineering support. Backstage, Dolby engineers worked closely with the show’s audio mixers, coordinators, Recording Academy representatives and production company personnel.
The show’s mixing engineers created a 5.1-channel program to accompany the HDTV broadcast, which was sent to Dolby DP563 Pro Logic II Encoders to automatically create the Dolby Pro Logic II soundtrack for analog stations. Dolby DP570 Multichannel Audio Tool units enabled the mixers to emulate a wide range of home environments for monitoring.
The 5.1 and Pro Logic II signals were encoded together into Dolby E, a Dolby professional audio technology designed for broadcast audio distribution, and sent from the Staples Center in Los Angeles to CBS master control in New York City.
