Bel Monitors at Australian Open Tennis


Gearhouse Broadcast recently purchased 52 Bel Digital Audio 3G HD compatible BM-A1-2SHD audio monitors/de-embedders and used them in their HD coverage of the 2012 Australian Open tennis championship in Melbourne.

Gearhouse Broadcast provides the technical facilities as the Host Broadcaster for Channel 7 which includes TV coverage from seven courts plus the World Feed and Channel 7’s unilateral facilities. They also provide uni-lateral facilities to ESPN and Tennis Channel from the USA and facilities to tennis Australia for their delivery to various platforms. The newly purchased 1RU units where used together with their current stock of the 2RU Bel boxes to provide all the audio monitoring in the entire facility.

The BM-A1-2SHD is a 1U high quality 2 channel audio monitor that de-embeds and permits the monitoring of the audio content of 3G, HD and SD SDI bitstreams but crucially maintains the simplest of control surfaces on the front panel. The unit was particularly suited to Gearhouse Broadcast’s requirements for this project because of its compact 1U size.

The BM-A1-2SHD accepts 2 x SDI sources and automatically detects between 3G, HD and SD SDI bitstreams, extracting the audio content appropriately. This automatic operation results in a very simple setup procedure and a very uncluttered and self explanatory front panel.

All available functions were accessible directly from the front panel via rotary controls, making operation extremely simple. A single 8-position rotary control enables the operator to monitor any channel pair from the selected SDI source. Two buffered loop-through outputs are provided for the SDI inputs.

The BM-A1-2SHD is suited to operation within Master Control Rooms, Outside Broadcast Vehicles, or indeed anywhere where audio monitoring of SD, HD and 3G SDI sources is required, especially when within a space conscious environment.
