Vancouver, B.C. Canada - October 14, 2008 - When John Riley, Chief Audio Technician for General Motors Place, had the daunting task of updating the sound system at GM place, he chose L- ACOUSTICS for its outstanding acclaimed performance.
The 16,900 seat arena recently went through a major upgrade of its sound reinforcement system utilizing world renowned L-ACOUSTICS line arrays, subwoofers and amplifier-processors. "We knew we needed to take this to a whole new level with a PA system that has outstanding accuracy and vocal intelligibility." says John Riley. "The dV-DOSC and dV-SUB arrays combined with the new SB28 subwoofers, provides an amazing range. The system delivers clear, perfect sound everywhere within the arena, with consistent, even coverage."
The new array-based installation was designed by Vaino Gennaro, Director of Live Sound Products for SENNHEISER CANADA (distributors for L-ACOUSTICS), in cooperation with Vancouver based ROCKY MOUNTAIN PRODUCTION SERVICES (RMPS) who provided a complete turnkey design for GM place. RMPS, an authorized dealer for L-ACOUSTICS, did an outstanding job with a team highly trained on L- ACOUSTICS gear. To everyone’s amazement they completed the install in three weeks, just in time for the first pre-season game
Using L-ACOUSTICS SOUNDVISION modelling software, Gennaro was able to verify coverage and create a detailed system model of the arena assuring acoustic accuracy and SPL levels deemed acceptable for the installation. Since the six dV-DOSC line-source arrays cover all audience and press levels of the arena, no delay speakers are required. The two dV-SUBs per array provide mid-bass reinforcement while the SB28s were included for enhanced sub-bass LF coverage.
What’s unique about L-ACOUSTICS is the patented DOSC waveguide technology used in dV-DOSC creates a precision cylindrical wave front that can be focused as accurately as possible above the glass to target just the seating areas. Since the main focus of the energy is above the boards, we can provide less interference for the players, broadcast engineers and an enhanced experience for the live spectator. All rigging parts and system components were included to minimizing fabrication and labour costs.
RMPS president - Fred Michael took Gennaro’s concept and built on it by adding several enhancements to the original system design, including adding additional dV-DOSC cabinets. "The new system comprises a total of six identical line arrays made up of 13 dV-DOSC cabinets topped with two dV-SUB subwoofers," explains Cory Allan, Western sales representative for Sennheiser Canada/L-ACOUSTICS. "The six line arrays are suspended from the high-steel rigging points and can be raised into the upper structure concealing them for concert events when necessary. Two arrays are facing the seating areas along the long sides of the arena, and one each for the ends. In addition, the design called for two groups of SB28 dual-18-inch subwoofer cabinets."
In total the new system comprises a total of 78 dV-DOSC active two-way, 12 dV-SUB and 16 SB28 enclosures, with complete rigging. Powered by a total of 23 L-ACOUSTICS LA8 four-channel/1800W amplified controllers.
L-ACOUSTICS' new LA Series of amplified controllers provides a unique combination of power amplifier, DSP, network control and comprehensive system protection in a single, ergonomic package. Using Microsoft Windows(r) operating system and GUIs, the LA Network Manager remote-control software provides command and monitoring of up to 253 LA4 and/or LA8 units within an L-ACOUSTICS L-NET network. The proprietary L-NET allows the configuration of multiple Ethernet network topologies across multiple zones, using CAT5e STP cables (or higher categories) and standard RJ45 connectors or IEEE 802.11 wireless.
