QSC & Adaptive Technologies Group Tackle Big Room Immersive Sound at CinemaCon

Immersive Overhead Cinema Mounts

QSC, a leading global manufacturer of cinema solutions, and Adaptive Technologies group, a provider of professional installed audio and video solutions, teamed up as part of the effort to temporarily convert the Colosseum at Caesars Palace into one of the largest cinemas equipped with Dolby Atmos immersive sound.

CinemaCon is a global tradeshow geared specifically for the motion picture theatre owner. The show expects to attract more than five thousand industry professionals. The Colosseum is where multiple studios promote their upcoming releases to the world’s theatre operators.

One of the great challenges inherent with a project of this magnitude is temporarily and safely installing all of the required overhead surround loudspeakers high above the floor without impeding sightlines for patrons sitting in the upper mezzanines. This year at CinemaCon, it was decided to raise the trusses (to which the overhead loudspeakers are attached) even higher to a “trim height” of 70 feet off the floor, to minimize visual obstruction for the upper level seating areas.

At that distance, even very high power cinema surround loudspeakers would lose pattern control and sound pressure level at the floor seating area, to the point where it would be difficult to meet the Dolby Atmos specification for SPL and coverage.

Fortunately, the extensive QSC loudspeaker catalog offered a solution. Sixteen pairs (32 loudspeakers in all) of WL2102-w WideLine-10 loudspeakers are clustered together, each pair operating as a single unit. The big challenge was that a pair of these speakers weighs over 160 pounds, and there exists no bracket that can support that kind of weight and also offer the precise aiming angle required to create the narrow vertical pattern of the combined unit. Working with Adaptive Technologies Group, a custom yoke-style bracket was designed that could safely support the load.

“Adding sixteen small line array clusters to the system created a level of complexity that rippled through the entire system design,” says Jon Graves, QSC product manager and the project leader for the audio system in the Colosseum at CinemaCon. “In order to accommodate all of these loudspeakers in their new positions, we had to re-engineer the Q-SYS network and add up to 77,000 more watts of power.”
The ultimate solution now uses two long ceiling trusses running front to back, with each truss suspending eight pairs of the WideLine-10 loudspeakers working as Dolby Atmos overhead surrounds.

“When Jon Graves approached us a few months ago, we didn’t hesitate one second to come up with the best suitable solution for this impressive temporary Dolby Atmos installation,” said Olivier Frans, Global Cinema Solutions Manager at Adaptive Technologies Group.

“We’re absolutely thrilled to partner with QSC and CinemaCon to make this extraordinary immersive sound experience happen.”
Adaptive Engineers designed an adjustable yoke mount that supports two speakers from one single point. Since minimal mounting points were available they had to use the M6 inserts on both top and bottom of the speakers. Yoke arms are secured on these top and bottom inserts. By means of slotted holes on the arms, the speaker allows for 0 degree, 2 degree and 3 degree tilt angles. Due to the minimal size of the inserts, a 3rd and 4th attachment was required to fully secure the speaker to the yoke mount. A heavy-duty safety cable was then attached to an eyebolt in the back of the speakers, and the other end was wrapped around the box truss for use as a redundant safety.
