The new facility in Hangzhou will feature Ravenna infrastructure and Lawo gear

Zhejiang Radio and TV Group (ZRTG), located in Hangzhou, China, has established a new production facility, the Zhejiang International TV Centre. The centre comprises a 42-storey main building housing several TV studios, and additional studios for music and film production

The facility’s audio relies on a RAVENNA digital network, controlled and monitored by Lawo’s Virtual Studio Manager (VSM), making this the first full networking of broadcast studios in China, with central routers distributing every signal required to be accessed by all of the studios within the center.

The ZRTG International TV Centre has two studio networks that are already in use. The main studio network comprises four large studios of 2,500, 1,200, 600 (A), and 600 (B) square metres. All studios are interconnected via centrally installed Lawo Nova73 routing system and video routing systems controlled and monitored by VSM. Each audio and video signal can be shared and distributed to the control room where it is required.

The audio network is designed using a Nova73 central router and four 56-fader mc²66 consoles in each control room. The studio control rooms have access to ten centrally installed DALLIS stageboxes that are connected redundantly to a Nova73 router via RAVENNA, which makes signal sharing extremely convenient with no local stageboxes required. 

The Studio A 600sq m control room also serves as the control room for the smaller 200sq m studio, where bands are mixed using a Pro Tools HDX and Pyramix DAWs. The 56-fader mc²66 can control the virtual faders of both DAWs simultaneously. There is also a Waves SoundGrid system at the Studio A control room, which is designed to be mobile so that it can be used in any of the other three studios if required.

The studio's new audio infrastructure includes Lawo mc²36 and mc²66 digital mixing consoles, along with Lawo DALLIS stageboxes, Nova37 and Nova73 central routers.

Owned by the local Government, ZRTG operates 12 television channels and eight radio channels, providing a total of 450 broadcast hours each day. Its satellite channel is the most successful in China, airing popular programs including “Sing China!” and ”Running Man”.

Beside the Lawo audio infrastructure, ZRTG has also invested in consoles from Lawo for its new 4k OB Van and Audio Truck. An mc²66 and two mc²56 mixing desks will be installed in the vehicles, whose coachwork is presently under construction in Netherlands. The OB trucks are scheduled to enter service in summer 2018.
