CheongShim Peace World Center relies on Optocore system

SOUTH KOREA: Fibre transport technology from Optocore has been installed at the
CheongShim Peace World Center, located just over 21 miles outside of Seoul in the Gapyeong District in South Korea’s Kyunggi province. CheongShim Peace World Center is owned by Unification Church (also known as Moonism), and is the largest multipurpose hall in the area.
The 127sq-m steel-frame structure boasts a 9m high arena that is put to use for various activities by the Unification Church’s general assembly, as well as for a range of corporate events, concerts, plays or commercial shooting. Paired with Yamaha equipment, the recently installed Optocore fibre system transmits audio digitally from the centre’s microphones to the FOH and the PA system to its large constituency. Without it, the size of the venue would be too big to transmit microphone signals over analogue lines.
‘We chose Optocore for its reliable optical transmission system, in order to ensure the audio would be heard throughout our large arena,’ said Kim Hanchoon, audio/video technical director, CheongShim Peace World Center. ‘Traditional cabling was just not going to be reliable enough, and while Optocore is still a rather new technology to many here in South Korea, we were happy to expose the team to Optocore’s fibre optic transmission method and all of the benefits that can be reaped from it.’
The equipment has been installed to support the sound control room as well as FOH. The Optocore DD32E system consists of three X6P-16IN units in the stage rack, each with 48 channels of analogue mic inputs to digital and one X6-16OUT with 16 channel digital to analogue converter. In addition, the DD32E provides AES/EBU feeds to the system’s loudspeaker DSP controllers at the main mix position, with a Yamaha PM5D mixing console loaded with one Optocore YG2 fibre optic card and two additional Optocore YS2 Slave cards that allow for up to 48 inputs and outputs to/from the Optocore network to the mixing console, as well as control of the X6 Optocore microphone preamps.
A Yamaha DM2000VCM mixing console resides in the sound control room loaded with an Optocore YG2 fibre optic card and two Optocore YS2 slave cards, which allow for up to 48 inputs and outputs to/from the Optocore network to the mixing console, as well as control of the X6 Optocore microphone preamps. Rounding out the system, the technical team uses speakers and a speaker control unit from Meyer Sound.
‘Having the Optocore system in place enables us to transmit signals by a fibre optic cable without noise or any audio loss,’ explained Mr Hanchoon. ‘When our audio is passing through small outputs such as at the microphone level, there is no noise to distract our constituents; they are hearing the sermon, loud and clear, which is something that’s very important to us.’
Mr Hanchoon added that he is pleased with the long-distance capabilities that fibre optic transmission has afforded to the church. ‘It’s often the case when using a multi-cable setup for a long distance signal, that there might be a loss of signal transmission caused by the circuit size that is over 200m, such as in our case. By utilising Optocore and fibre optics instead, we can overcome the distance barriers, ensuring smooth, reliable transport every time.’
‘We are so pleased to provide such a complete solution to the A/V team at CheongShim World Peace Center,’ enthused Tine Helme, director, Optocore. ‘The fact that our system can be used in three ways – as an electrical transmission system by multi-cable (analogue), signal transmission of console and stage box (using PM5D and DSP50) by UTP cable, as well as optic transmission – is further proof of the unprecedented benefits that fibre transport can bring to even the most challenging of situations, such as CheongShim’s large venue.’
