Sound Meter Monitors Audio for 2010 EXPO, 2010 Asian Games and Other Major Events

BEIJING, CHINA, 30 AUGUST, 2010 ─ RTW, a leading manufacturer and distributor of professional audio metering and control devices, proudly announces that Sony China Professional Solutions Group has deployed the company’s SurroundMonitor 10800X-PLUS for use on its new HD OB van. In one of its first applications, the RTW sound meter is helping production team members on the van quickly and easily monitor audio for live broadcasts of some of Asia’s biggest events, including EXPO 2010 and the upcoming 2010 Asian Games.

The SurroundMonitor 10800X-PLUS is the ideal monitoring tool for the fast pace and tight turnaround times typical for the live broadcast of such mega-events as EXPO 2010, the “World’s Fair”-style exposition currently taking place in Shanghai until 31 October. It conveniently displays all surround sound information on one split screen, allowing busy sound engineers to check at a glance a broadcast’s multichannel ppm level, phase, sound balance, center presence and overall volume. The Sony OB van’s SurroundMonitor 10800X-PLUS is also equipped with the latest firmware update, which enables it to measure loudness in accordance with the ITU BS.1770 recommendation.

“The Sony OB van was designed to handle live broadcasts of some of China’s most high-profile events, which makes for a very frenetic production environment,” says Ma Jianguo, general manager, Beijing Viaudio Tech Co., Ltd., which performed the van’s audio system design and integration for Sony. “It was essential that any equipment going into the van made it as easy as possible for the crew members to do their jobs. The fact that the SurroundMonitor 10800X-PLUS displays all necessary information on one screen has made this possible. It offers excellent audio monitoring and a level of convenience that is very much appreciated by the sound engineer and other staff members.”

The SurroundMonitor 10800X-PLUS also lends a great deal of monitoring flexibility to the Sony OB van. It can handle up to eight channels of measurements, for both analog and digital signals, enabling monitoring for virtually any type of broadcast production. The meter also features other useful tools, including a 10-way correlator, an audio spectrum analyzer able to measure 31 bands of audio, a real-time audio vectorscope and AES/EBU status display.

“At RTW, we specialize in offering easily implemented solutions to complex production challenges such as the live broadcast of EXPO 2010, the 2010 Asian Games and other high-level events,” says Andreas Tweitmann, managing director, RTW. “We understand that when it comes to monitoring sound in these types of high-stress situations, customers need equipment that is easily accessible and easy to use. We are proud that Sony China Professional Solutions Group has recognized this and has chosen to implement the SurroundMonitor 10800X-PLUS for the many prestigious events it covers.”

RTW’s SurroundMonitor 10800X-PLUS was the first audio visualization system to use RTW’s unique Surround Sound Analyzer, featuring a fast and easy graphical representation of surround signals. Today, it is known around the world as an invaluable aid for monitoring peak levels, ITU loudness, channel balance and surround sound in broadcast, recording, post production and mastering. For many of the existing units, a software upgrade kit with partial ITU loudness measurement functions is available.

Once the Sony OB van finishes broadcasting EXPO 2010, it will move on to cover the 2010 Asian Games, taking place 12 through 27 November, 2010, in Guangzhou, China.
