China’s Largest Intercom


Beijing Television (BTV) picks Riedel’s Artist intercom system for its new studio complex.

The system, which is currently being installed by Beijing based system integrator ATC Technology, will include 6x Artist frames connected over a redundant fiber ring and over 170 panels, making it currently the largest intercom installation in the country. “We were very impressed with what Riedel has to offer,” said Mr. Zhou Xuhui, Director of Technical Equipment Department of BTV. “It was the combination of features and flexibility that lead us to our choice.”

The new installation will serve 12 studios and 1 master control room using mainframes of various sizes including 5x Artist 64 frames and one Artist 32 frame. All six frames will be linked via fiber to form a single decentralized non-blocking intercom matrix. For the system BTV decided on Riedel’s 2000 series LCD display panels.  The 2000 series panels provide 8 character LCD displays, the ability to individually adjust the volume of any source and a digital connection to the matrix via either CAT-5 or coax cabling.  “For us the panels offered the best balance between functionality and cost,” commented Mr. Zhang Jing, Producting Technics Project Manager of BTV.

In addition to the matrix frames and control panels, BTV added a number of other components to the system.  12x C44 digital partyline interfaces, 50 x C3 two-channel digital beltpacks and 16 CD-2 desktop speaker stations provide broadcast quality digital audio to all partyline intercom locations on industry standard XLR cable.  Five Connect Solo analog telephone hybrids integrate telephone lines while four Connect IP interfaces bring VoIP functionality to the system. “We’re very pleased and look forward to working with Riedel in the future,” said Mr. Li Xun, Vice Chief Engineer of BTV.
