CCTV turned to CSS Group to update its OB vans
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 Wohler Technologies 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, was implemented into the truck to monitor CCTV’s various audio signals in the field.
“We needed a solution that could support Dante, AES67, SMPTE 2022-6, SMPTE 2110, MADI, AES, analog and SDI 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).
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 configuration with role-based authentication that protects critical configurations from unauthorized alteration.
