As the host broadcaster supporting 14 international networks, CTV's Olympic post sound supervisor Mike Nunan has continued his use of Optocore in critical International Broadcast Centre applications by creating a 100-plus channel routing network at the International Broadcast Centre between his edit suites and his post sound control room, utilising DD4ME MADI interfaces, DD32E AES network devices, X Series remote preamp/converters and YG/YS interface cards. Additional signal transport and remote control via Optocore is the interfacing of numerous Neumann Solution D digital microphones.
For the opening and closing ceremonies at Vancouver's BC Place, Norwest Productions, Australia's largest audio company, were tasked with various responsibilities including remote preamps for FOH, monitors and East, West and Centre stage positions. Consoles chosen this time around included a Digico D5 at FOH and a PM1D for monitors, receiving a mix of AES and MADI signals. In addition to those five positions stadium locations, the eight-node ring was completed with Broadcast, Communication and FOH analogue patch network addresses.
Specifically an Optocore DD4ME MADI interface was used with the D5, Optocore YG/YS cards for the Yamaha PM1D DIO8 rack, and six distributed Optocore DD32E AES-capable network devices with combinations of X6 Series Optocore A/D converter modules.
Le Studio Mobile was awarded the challenge of capturing the opening and closing productions. Effortless integration was accomplished via a single DD4ME dual channel MADI interface with BNC connection.
In preparation for hosting all the Olympic hockey events, the17,000 seat Canada Hockey Place (GM Place) arena, located next door to BC Place, recently underwent a complete audio refit based on an extensive Optocore network that included their expanded broadcast facilities. The innovative design circling the building carries audio, video, intercom and data for all DSP-based products such as signal processing and wireless microphones.
The reconfigurable network allows staff to position their Soundcraft Vi6 console at one of three mix positions around the building with instant connection to the remote preamps located in central patch at ice level, offering their clients flexible set-ups.
