082 VENUE
The design brief for the Sohyang Arts Center was to create an ambient acoustic environment, which could switch from mimicking an intimate music hall to a vast performance space. The PA system design was handled by Meyer Sound’s Bob McCarthy, who also handled Seoul’s Sang Nam Hall, LG Center.

The system uses a total of 157 small mid-high loudspeakers, these are a combination of Meyer Sound MM-4XP, UPM-1P, UP-4XP, UPJunior and UPJ-1P VariO loudspeakers, all of which are precisely positioned in the auditorium to guarantee an optimal reverberation system. The loudspeakers are supplemented by 12 Meyer Sound UMS-SM compact subwoofers that are concealed within the side- walls and over the stage.
A total of 40 miniature microphones complete the Constellation sys- tem, which is built on Meyer Sound’s D-Mitri digital audio platform.
The D-Mitri core of the system comprises 17 frames, including four DVRAS processors - for the four acoustical zones - plus addition- al frames for core processing, input/output, GPIO, mixing, and WildTracks digital recording and playback. As acoustical fl exibility was a high priority for this space, Song Dae- young made some specifi c requests. “I asked the Constellation team to provide six presets with enhanced reverberation times from 1.3 to fi ve seconds,” he said. “I know fi ve seconds is not necessary, but it does demonstrate to some guests how dramatically Constellation can change the reverberation time.” Avix Tech’s Lee Sung-bok admitted that the installation of the system itself did prove diffi cult, purely from a lack of experience point of view. However, with guidance and support from Meyer Sound HQ, he - along with his team Eric Han and Tom Jung - were able to ensure that each and every element of the Constellation system was installed according to the exact specifi cations and that the wiring and cabling between the loudspeakers and the processor platforms was truly accurate.
Alongside the Constellation system is a sound reinforcement system, the two are usually combined when jazz or classical rock concerts take place at the arts centre. The SR system comprises two hangs of four Meyer Sound UPQ-1P loudspeakers per side - with a wide operating frequency range of 55Hz to 18kHz - left and right of the stage and a central line array cluster featuring 10 Meyer Sound Mina curvilinear array cabinets - which are ideally suited to a high-fi delity sound reinforcement system - coupled with two Meyer Sound 700- HP subwoofers.
The FOH console at Sohyang Arts Center is a DiGiCo SD7, supplied by the manufacturer’s Korean distributor, Soundus. Although General Director Song Dae-young was originally looking at an analogue mixing desk, upon reviewing the performances the console would need to cater for (including the Busan International Film Festival once a year) the decision was made to opt for a digital desk instead. The SD7 has integral I/O of 12 analogue inputs, 12 analogue outputs and 12 AES I/O mono channels meaning the desk is equipped with a total of almost 1,400 audio connections. Its fl exible worksurface also makes it user friendly for touring productions that perform at
