indoor sports facilities represent the most challenging facilities in our industry. The shape is not conducive to high-quality sound.” The VLA601-WRC loudspeakers employ three 2431H 1.5-inch exit / 3-inch diaphragm high-frequency horn-loaded compression drivers with a 60º horizontal coverage pattern, two CMCD-82H 8-inch- cone midrange compression drivers and two 2226H 15-inch woofers loaded into JBL’s WRC weatherised enclosures. Derived from JBL’s VerTec Series line array systems, VLA Series loudspeakers are designed to provide high-SPL sound at throw distances beyond the reach of traditional loudspeaker designs and offer a choice of 30°, 60° and 90° horizontal horn coverage patterns. Wolfe explained: “Pattern control is the key to maximising the performance of a sound system in a large venue, and by ‘pattern control’ I mean control over as large a range of frequencies as possible. A tall line array helps with vertical pattern control and the VLA product does extremely well horizontally. No other product was available with these performance characteristics. Fortunately, Clair Brothers felt exactly the same way.” Devenney confirmed: “We use the VLA Series line arrays in a lot of stadium and arena projects because of the defined coverage they provide, and because good articulation is important in spaces like this.” Previously, the speakers were hung from the roof but with its retractable replacement, the clusters hang on winches. “We had to work closely with all the other parties involved in the renovation to coordinate the installation,” explained Jim. “We had very little time to hang the clusters because they were putting down the artificial turf at the same time. We actually built the clusters outside of the stadium and brought them in on a truck to set them up quickly.” A total of 157
Lab.gruppen PLM Series amplifiers have been specified - 112 PLM 10000Q and 45 of the Swedish manufacturer’s flagship model - the PLM 20000Q - which represents the largest single fixed installation of PLM power in the world to date. Both models support audio transport via Dante - Audinate’s digital audio networking protocol - which was central to the audio integration at

BC Place. The monitoring and the audio transport are all via Dante, across one network along with system control, on a fully-redundant network topology. The PLM Series’ on board Lake Digital Audio Processing speaks to Peavey’s MediaMatrix nWare software, which controls the MediaMatrix NION n3 audio processors. This was made possible by TechSpa’s development of the existing Peavey software. Regardless of their power capabilities, the PLM Series amplifiers come equipped with Dante networked audio distribution, Lake Processing and load verification with real-time monitoring. The PLM 20000Q was developed to deliver unrivalled power over four channels, with each channel rated at over 5,000W into 2.2 - 3.3 ohms. Originally created to meet the demands of high-performance touring, with Clair Global as a key early customer, it quickly gained a reputation as an equally potent solution for the installation market because of its very high power density, low mains consumption and its aforementioned smart system control and tuning features. The PLM 10000Q offers very similar functionality with four channels of 2,350W at two ohms. The PLMs’ network buddy where this system is concerned, the MediaMatrix NION n3, is part of a series renowned for stability, efficiency and robustness. It boast 448-channels of high-speed digital audio bus for seamless expandability and offers a low-latency audio path suited to projects as huge as BC Place. Discussing the collaborative nature of the project,
Lab.gruppen’s Josh Evans highlighted Peavey’s roll: “Peavey’s support was amazing - they were on the job site a lot. They also helped with the development and gave the thumbs up that we should do the Lab. gruppen / Peavey module.” Audinate’s Dante brings BC Place’s audio infrastructure together with minimal hassle and high performance. Regarded as a true plug-and-play digital audio network, it utilises standard internet protocols over Ethernet, and provides reliable, sample accurate, low latency distribution. Over 500 Dante channels have been used at BC Place. If a Dante network of that scale was translated into other
