When CCTV, China s major public broadcaster, launched an initiative to update its OB trucks to 4K, it turned to CSS Group to supply the most suitable equipment for the station s upgrade. For audio monitoring, CSS Group relied on its 15-year-relationship with Wohler Technologies, a leading manufacturer of video, audio and data monitoring solutions, to provide its high-quality audio signal monitoring and metering solutions. Wohler s iAM-AUDIO, which monitors a mix of analog, digital and IP signals easily and transparently, was implemented into the truck to monitor CCTV s various audio signals in the field.
CCTV provides top news and content to China and around the world. The channel s programming includes a broad range of variety shows, sports and travel programs. When CSS was tasked with designing and equipping the station s upgrade to fully 4K capable vehicles, the group trusted in its longstanding relationship with Wohler and knew that it could rely on the company s well respected product range and set of advanced technologies to enable accurate, high fidelity monitoring of multiple audio signal formats.
"We have a great relationship with Wohler and have been using its products for many years, says Song Xuan, general manager of CSS Group s Audio Division. "We had previously recommended Wohler s AMP2-16V and AMP1-S8MDA solutions extensively. Wohler s exceptional quality and attention to detail is something that we have grown accustomed to. When upgrading CCTV s truck to 4K, we knew we needed a reliable but versatile solution that could support Dante, AES67, SMPTE 2022-6, SMPTE 2110, MADI, AES, analog and SDI formats, and we didn t have to look any further than Wohler Technologies and its iAM-AUDIO solution. The equipment s interface allows CCTV to accurately monitor a variety of signals within a single unit and ensures its 4K OB truck can produce the best programming possible."
Wohler s iAM-AUDIO is seamlessly integrated into CCTV s 4K OB audio system, which is based around a suite of products from Lawo. iAM-AUDIO monitors AES67 audio from its Lawo mc266 console, along with analog and AES signals. Audio is being routed using Lawo s Nova73 and its DALLIS remote and desktop interface system. CCTV also utilizes Lawo s sapphire mixers connected to a Cisco Gigabit Switch in addition to an audio-follow-video (AFV) switch. Using Wohler s API, the iAM-AUDIO units have the further option of being centrally and remotely controlled by Gefei (or other control solutions, such as Lawo s VSM).
iAM-AUDIO is designed to be easy to operate yet powerful enough to provide high-quality, intuitive monitoring of multiple signal types within a compact form factor. iAM-AUDIO s touch screen panels allow for intuitive control, with simple to navigate menus and configuration. All iAM Series monitors are built with an on-board web server and can be updated, monitored and controlled via a browser-based user interface that supports fast configuration with role-based authentication that protects critical configurations from unauthorized alteration.
