EAW OTTO ARRAY with two ports, that means double the Cat- 6 cabling to each one, double the network switches and ports, and so on. That made for a relatively complex integration process. “It’s about 250 Ethernet ports in total, so it’s a massive network, and then you have to run that Cat-6 to all the cavities throughout the building,” says Solotech’s Lemay. “I think some people were surprised at just how much cable infrastruc- ture we were dealing with.” He adds that the process was com- pounded by the project’s odd schedule. The initial plan was to handle the installation in the summer of 2019 between the Cana- diens’ seasons; however, the arena was still relatively busy, and the bowl audio system is tied into the emergency paging system for the building. That meant the system needed to be steadily operational so, as Lemay says, “We couldn’t just shut everything down for a few days and do it all at once.” As such, they broke the job into two phases. The first involved the installation of 22 EAW MKD1096 delays on custom brackets to cover the upper-bowl seats behind the ven- ue’s wrap-around press gallery and was done a week ahead of the 2019/20 NHL season. An additional four MKD1096s were hung under four of the Otto arrays to cover the ice surface 28 PROFESSIONAL SOUND for the players. All are driven by a complement of seven UXA4410 amplifiers with Dante. The second phase involved the Anna and Otto arrays covering the bowl, which was done over a few non-consecutive days in late 2019. On the first of those days, they got four of the 16 hangs in the air – which Lemay notes went rather smoothly – and then spent the rest of the day tying them into the net- work and getting their data verified by EAW. Two days later, they had another window to go in and match the EQ of the four new arrays with that of the previous system so that they’d work uniformly for a single game. “That was our ‘hybrid system,’” Lemay says with a laugh, noting the challenges of temporarily tying the two systems together. “The technologies are completely different, so it’s not like we could just change amps and plug in the same wires.” For that game, he was joined by SFM’s Paolo Bizzarro – the firm’s lead on the proj- ect from the outset – and a rep from EAW to assess and validate the system’s coverage and performance. A few days later, they flew the rest of the arrays, had everything configured, and did another assessment at the next home game. The day after that, they went in for fine-tuning and basically prepared to hand the rig over the Leveille and his team to assess on their own over the course of a few weeks. Ever since, they’ve been taking notes on performance and total coverage in preparation for commissioning in late Feb- ruary, at which point a SMAART engineer will come in for final tweaking. To ensure they were as lean and effi- cient as possible during their limited time in the arena, the team at Solotech went to great lengths to prep and test as much as they could in their Montreal headquarters ahead of the install. As Solotech’s Technical Project Manag- er, Ghislain Veronneau, explains, “The main reason it worked was that we prepped all the clusters in advance the week before the first installation phase, so everything was nearly pre-assembled.” That involved assembling all of the arrays, organizing all of the cabling, and testing each individual cabinet. They also set up the Q-Sys networking backbone to ensure it was running smoothly. After that, each Anna array was split in half and put onto pallets with their Otto counterparts to be trucked over to the venue. “Then, we basically just had to put one on top of the other and winch it up,” says Veronneau. “Like any AV project, the more energy you put in before the actual install,
