When they restarted the competition in early 2019, EAW and the brand’s Canadian distributor, SFM, were among the suppliers invited to take part by first proposing a system design that would meet the venue’s extensive criteria. From there, three man- ufacturers were invited to come into the building with a demo system and showcase its capabilities in a real-world setting. It was a sizeable investment, after all, and Groupe CH wanted to interface directly with the suppliers to ensure they’d have full support throughout the lifespan of the system. A consulting team was assembled at the outset of the process that included: Arthur Skudra, the owner and principal consultant with Ontario-based Sightsound Consulting; Las Vegas-based audio industry veteran and Truth in Audio founder Bernie Broderick, who spent 12 years with EAW from 2006-2018; previous A1 Michel Leveil- le, considering his unparalleled knowledge of the building and its audio requirements; and Solotech sales rep Mario Lessard. Owing to the Montreal-based AV and en- tertainment technology giant’s longtime partnership with the Bell Centre, Solotech had been selected as the integrator for the winning system from the outset. Sylvain Lemay, Solotech’s lead for the physical installation, also joined the fold for the final-three shootout. He and Leveille were close from their touring days and Leveille specifically asked that he head up the install. Arguably the biggest stipulation for the new solution was that it occupy the same 16 cavities in the overhead arena-wide walking grid as the previous one since reengineering that grid would be cost- prohibitive. It needed to work in various smaller configurations, including a left-right performance system for a half-bowl setup as the Bell Centre is one of the busier NHL are- nas in terms of the amount of non-hockey events it hosts. It also needed to be state- of-the-art in terms of its sonic performance, feature set, operation, and maintenance in order to deliver the desired 20-plus-year lifespan like the previous system. Of course, those were in addition to a notable improvement in coverage and clarity from the first row of rink-side seats to the very top of the upper bowl. That meant pushing enough air to overpower a crowd that can approach 110dB with relative ease – especially when the Bruins or Leafs roll into town. Ultimately, the Adaptive Series solution from EAW and SFM won the day by check- EAW ANNA ARRAY ing all of those boxes and then some. Key to that are features like Adaptive Performance, which manages coverage and directivity parameters electronically via EAW’s Res- olution 2 control software, thus forgoing vertical splay angles to achieve the desired coverage, and Adaptive Healing, which can self-detect any component failure within the enclosure – say a driver or port – and compensate for it automatically. The remote control of directivity meant that the EAW solution – comprised of the mid-sized Anna three-way, fullrange array enclosures and Otto Adaptive subwoofers – could easily and effectively occupy the ex- isting 16 grid cavities while negating the need for curved arrays. That meant fewer total boxes to cover the entire arena. Each Anna array encircling the ice sur- face from above includes six modules for a total of 96. Some arrays are paired alongside hangs of two or three Otto subs for a total of 36. A unique and attractive feature of the Adaptive subwoofers is that each individual module can be configured in omni, cardi- oid, and hyper-cardioid modes (or anything in between) by internally and automatically balancing its output with cancellation. The adaptable directivity combined with the sheer number of cabinets was a big advantage in meeting the objective of reconfigurability. “The fact that we’ve got so many boxes and that they’re self-powered makes the system very flexible in terms of different configurations for different types of events,” offers Leveille. “We can build in presets and recall them as needed without actually moving anything, so it’s not just easier; it also helps reduce costs and set-up time for events.” Redundancy was a key consideration for every component of the system as well. In addition to the Adaptive Healing capabil- ities of the Anna and Otto boxes, the QSC Q-Sys network (essentially acting as the system’s distribution matrix, since the DSP is handled within the cabinets themselves) is fully redundant thanks to a pair of identi- cally-configured Core 510i integrated pro- cessors. Since each cabinet is also equipped PROFESSIONAL SOUND 27
