CCTV scales up on live multi-track mixingMarch 15, 2017
Chinese state broadcaster recently added Merging Technologies’ Pyramix 10 digital audio workstation to its arsenal
When working on large events and variety shows, live multi-track mixing is an “extremely important” part of the production process for Chinese state broadcaster CCTV.
Needing “highly stable and reliable” equipment that would allow long duration, high track-count multi-track recordings, CCTV turned to Merging Technologies’ Pyramix 10 digital audio workstation, equipped with Horus networked audio interfaces.
For a Chinese folk song competition held last year in Beijing, CCTV used Pyramix V10 systems for the first time and recorded 128 tracks for more than 12 uninterrupted hours.
This was followed by the deployment of Pyramix in September for the coverage of the opening ceremony of the 2016 G20 Hangzhou summit.
Yuan Xuechang, recording engineer at the audio department of CCTV, said: “Pyramix has a clever DSP (digital signal processor) architecture. Its hardware, software and file format compatibility is very comprehensive. It has the ability to deliver stable ultra-long recording and playback of over 100 tracks and is able to handle all large and critical events.
“In addition, Pyramix provides us with an excellent compact audio interface, great clock for synchronisation and has a user-friendly monitor control. For that reason, Pyramix was able to successfully perform at the G20 summit — the programme was recorded and edited for live TV broadcasting.”
CCTV is also in the process of commissioning a new OB truck that is based on a total IP solution for video and audio. The audio part will feature a console from Lawo, while another Pyramix MassCore 128 will be used as its main recording system.
