The New Macedonia Baptist Church in Riverdale, GA sports SymNet 8×8 DSP units to handle routing and signal processing in its audio system. Riverdale, GA (August 28, 2007)–New Macedonia Baptist Church in Riverdale, GA, hired United Technology Service, Inc. (UTS) to design and install an audio and infrastructure system for its brand-new, 1,300-seat facility which opened this past spring. The result was based around a trio of SymNet 8×8 DSP units which field appropriate routings and signal processing for all of the church’s common uses.
UTS systems design engineer, Tony Crabtree, led the project. “We demo’d all the major brands,” he reported. “The SymNet 8×8 DSP was obviously the most musical.” It was also CobraNet compatible via the SymNet CobraLink, allowing it to be connected to a local VLAN network and accessed remotely for servicing. Crabtree explained, “If a New Macedonia staff member calls me on Sunday morning because they’re not getting any sound out of their main speakers, I can hop on my computer from the office or home and get access to everything in the system. I can see signal flow, trace the good signal to where it’s broken, and fix the problem, as long as it’s not something physical.”
The three SymNet 8×8 DSP units are augmented by a SymNet BreakIn12 and BreakOut12, which provide 12 A/D inputs and 12 D/A outputs respectively in addition to the 24 that come with the three 8×8 DSPs. The system combines live audio with the church’s AV system via a Crestron touch-panel controller. Via the controller, users can select between a Sunday service setup and meeting setup. Selecting meeting setup causes the system to bypasses the 40-channel Soundcraft MH4 console so that no sound engineer is needed. The SymNet 8×8 DSPs take over with automatic mixing of five Shure wireless mics, as well as CD player, cassette player, and video system inputs. Using the touch-panel, users simply select their program source and adjust the program and speech audio levels.
Crabtree chose to amplify the EAW left and right line arrays, the EAW center horizontal cluster, and the massive block of EAW subwoofers below the stage with QSC CX and PL series amplifiers because they are CobraNet linkable. “We tried to keep the system as small as possible without sacrificing fidelity or usability,” Crabtree added. “The trick was in picking the right equipment and positioning the speakers. I modeled the room in EASE and discovered that while the left and right line arrays would work nicely, a center cluster using asymmetrical horns was needed in place of the center line array that was initially called for.”
Crabtree added, “I programmed a Super-module for the EAW line array that is composed of a number of SymNet’s nearly 300 smaller modules. The next time I put in an EAW line array, all I have to do is drag and drop the Super-module from the New Macedonia system into the new system. That will save a lot of time down the road.”
