Greenhill School, founded in 1950 and whose 14 buildings are situated on 75 acres in Addison, Texas, places a good deal of emphasis on both athletics and civics, so a scheduled memorial ceremony for the anniversary of 9/11 was important to students, teachers and parents. However, the sound system in the school’s gymnasium wasn’t up to the task anymore. But Guitar Center Professional (GC Pro), the outside sales division of Guitar Center that focuses on the needs of professional users, was able to fix that, and quickly, too. Once GC Pro’s team had evaluated the situation, made their recommendations and bid, and brought in a member of their GC Pro Affiliate Services Program as the systems integrator, the new sound system was put up and in place within a single day, ready for the observance ceremony. Integrator Trinity Group International installed a GC Pro-provided QSC WideLine line array sound system consisting of two hangs each with subs attached below.
