“Blackbird Studio C was already equipped with stereo ATC SCM300ASL Pros so adding a matching center was a natural choice. The ‘base’ specification for Dolby Atmos music systems is 7.1.4 (7.1 plus four overhead ‘top’ speakers), but because Studio C is larger than average, the surround speaker count was increased by four to make the system 9.1.6. The choice of surrounds speaker model and the number of subs was based on the room size, listening distance, and target SPLs at the listening position. Dolby’s DART tool helped select suitable monitors based on the room and acoustic data input into the tool.” Four of the ATC SCM0.1/15ASL subwoofers are positioned along the front of the room and two are positioned on the side walls closer to the back, as determined by a judicious combination of measurement and expert opinion.
“John [McBride] called me to describe a full ATC Dolby Atmos room at Blackbird, and I was impressed by his vision and also by the amount of gear it would require,” recalled Brad Lunde, founder and president of TransAudio Group. “Then he said he wanted it all delivered in two weeks to allow a week of installation ahead of a critical deadline. I love John, but I said, ‘you’re out of your mind, there’s no way!’ But of course I called ATC’s UK manufacturing facility and asked if it would be possible to deliver six flyable SCM100ASL Pros, six stand-mounted versions, a single center SCM300ASL Pro, and six subwoofers. They would have to work miracles to get them all built, but they made it happen!”
“Given how few Dolby Atmos mixing rooms exist in the world and given John’s very high standards, it was strategically important to do an outstanding job, with plenty of insurance against any conceivable problem,” Lunde noted. In addition to Zach Winterfeld, who has deep experience with precision measurement systems, TransAudio Group sent Tony Marra, who operates the TransAudio Group in-house repair shop, to Nashville for installation and tuning knowing that between the two, they had the wherewithal to diagnose and repair anything that might need it. ATC sent Ben Lilly, who worked closely with the TransAudio Group team. The team dug into the analog processing capabilities of the integrated ATC amplifiers to make subtle adjustments to Blackbird’s existing SCM300ASL Pros, which had been in continuous use for nearly a decade, to match the new center channel SCM300ASL Pro. Ceri Thomas and Christine Thomas from Dolby saw to it that all of the Atmos specs were dialed in to perfection.
, so I guess no 5.0 releases then
