One of three convention facilities in the Boston area, the 23-year-old John B Hynes Veterans Memorial Convention Center is several years into an on-going, multi-phase renovation project.
The venue is currently completing an upgrade of its audio systems, courtesy of Boston-based Adtech Systems. The project incorporates acoustical treatment and sound system upgrades to bring the exhibit halls up to US NFPA72 code standards for voice evacuation and speech intelligibility. ‘There are four exhibition halls on two floors,’ says Adtech’s Charles Crane. ‘Halls A and B are on one floor and can be combined; Halls C and D are on another floor and they can also be combined.’
When the entire facility is booked for a large event like MacWorld, the system has the ability to page in all spaces, it is able to use a matrixable environment that allows any source can go anywhere.
The new system was designed by Communications Design Associates, who also performed the needs analysis and qualified the system. This is based around Community R-Series loudspeakers in Halls A, B and D. Halls A and B used a total of 165 R2-94Z three-way loudspeakers fitted with TRC400 transformers. A total of 31 R.5-66TZ two-way loudspeakers are installed in exhibit Hall D.
More than 60 Crown CTs amplifiers with PIP modules power the system, with signal processing covered by BSS London DSP. Online monitoring and control of the amps, the London DSP, and even the SurgeX IT power conditioning is handled via HiQnet System Architect software.
Crane credits the defined coverage of the R-Series as a major factor in their selection for the project: ‘Their radiation patterns fit the bill for coverage,’ he says. ‘We wanted proper direct field coverage, and the customer wanted to ensure high speech intelligibility. The consultant modelled it out and they hit a home run in coverage.’
