Education – Symetrix offers sound solution at Indonesian school

Andrew Brister 25 January 2012

Zion School recently completed construction of a brand new building in Makassar, South Sulawesi in Indonesia. The school serves over 700 students from kindergarten through high school and uses state-of-the-art technology to connect with pupils and to prepare them for an increasingly technological world. A case in point is the school’s 750-seat multipurpose auditorium. The auditorium will be used for seminars, meetings, graduation ceremonies, and performances. Symetrix distributor PT Gracia Auvindo supplied an adept, but cost-effective Symetrix Jupiter 8 to handle all of the audio processing in the auditorium. Local dealer JK Sound in turn furnished the unit to the school, and both companies helped install it. “The processing power of the Symetrix Jupiter is substantial, yet it’s easy to set up and very affordable,” said Hendra Halim, technical manager with PT Gracia Auvindo. “At the Zion School auditorium, just one Jupiter 8 handles everything.” Coda Audio full-range loudspeakers and subwoofers powered by beefy Camco amplifiers give the students at Zion School high performance fidelity and impact. Full stereo separation heightens the excitement.@page_break@ 
The school uses one of the Jupiter’s many apps, which creates a sound processing and mixing tool that is specific to the needs of the auditorium. “The app gives us feedback fighters, parametric equalisation, and full loudspeaker management processing, among other modules,” said Halim. “Everything – from the output of the mixer to the monitors to the mains – is handled by the Jupiter 8. The speaker manager provides the crossover between the full-range boxes and the subwoofer. Moreover, the Jupiter 8 sounds fantastic, and the school doesn’t have to worry about feedback or unintelligible audio.” In addition to the Jupiter 8, a Symetrix Zone Mix 760 handles school-wide paging and background music. Six zones comprise the school, and three strategically-located paging stations provide input. At each station, a wall-mounted Symetrix ARC-XLR push-button XLR input with an attached microphone allows for easy paging. The ARC-XLR’s four selector buttons combine with an ARC-SW4’s four selector buttons to direct pages to any or all of the building’s zones. Setting up the Zone Mix 760 to automatically duck background music for pages proved straightforward. QSC ceiling speakers and amplifiers complete the school-wide paging system. “We’re very excited about Symetrix’ Jupiter, Integrator, and Solus families of processors,” said Halim. “They provide a comprehensive and well-thought-out collection of solutions to every audio installation challenge. The products are functional, reliable, and great sounding. The installation at Zion School went smoothly for us. It took just over a day to get everything in place and tuned to perfection. After a brief training session, staff at the school are totally comfortable operating it.” www.symetrix.co
