Studio Technologies LL-3G-CA-075 with LL-3G-CR-075 – Live-Link Sr. Portable Fiber Transport System Studio Technologies

LL-3G-CA-075 (portable w/PL intercom) with LL-3G-CR-075 (portable w/4-wire intercom)

Designed to handle news, sports, and other day-to-day remote interfacing needs with ease, the Live-Link™ Sr. Remote Camera Interface System offers a comprehensive fiber-optic-connected solution for transporting digital video, audio, intercom, and data between a remote camera location and a truck or control room. The point-to-point system consists of a portable Camera End Unit and either a portable or rack-ready Control Room Unit. Both use industry-standard connectors that are clearly labeled for fast, intuitive setup.

Live-Link Sr. provides two digital video paths in each direction that support the 3G/HD/SD-SDI SMPTE®-standards. In addition, the system provides connectivity for mic/line level signals, talent cueing, 2-channel party-line intercom, GPI/GPO, RS-232/RS-422 asynchronous data, and Gigabit Ethernet. A full complement of status LEDs simplifies monitoring and troubleshooting. Live-Link Sr. systems are suitable for remote production or permanent installation and can be powered by a DC supply or battery.

Live-Link Sr. is a reliable and convenient way of linking a production camera crew to an ENG or OB van, SNG vehicle, or production trailer. The system’s portability and ease-of-deployment make it an ideal infrastructure solution for studio complexes, arenas, and campus environments. Live-Link Sr. units interconnect using two strands of single-mode fiber-optic cable and provide a transmission distance of at least 10 km (per SMPTE 297). Featuring the rugged opticalCON® DUO fiber-optic connectors from Neutrik®, units can also be ordered with ST optical connectors.

• Low power consumption allows extended battery operating time
• Industry-standard connectors for all inputs and outputs
• Available in portable or rack-ready versions

Live-Link Sr. Camera End Unit
The Live-Link Sr. Camera End Unit goes where the action is. Weighing less than 11 pounds (5 kg) the unit is truly portable. And with its rugged aluminum housing it’s built to withstand the rigors of field use. The intuitive I/O panel uses industry-standard connectors: BNC for digital video, 3-pin XLR for audio and intercom, RJ45 for Ethernet, and 9-pin D-Sub for asynchronous data. Status indicators and multi-segment audio level meters make setup and use a simple process. The 2-channel party-line intercom interface provides DC power for direct connection of intercom beltpacks. The 10/100/1000 Ethernet interface features an auto MDI/MDI-X input eliminating the need for crossover cables. An Anton/Bauer battery mount allows for battery-powered operation. A maximum power draw of 30 watts allows battery operating time of four hours or greater. As an alternate to battery operation a source of 10 to 18 Vdc can be connected.

Live-Link Sr. Control Room Unit
Typically residing in an ENG truck or at a control room location, Live-Link Sr.’s Control Room Unit serves as the I/O panel for signals going to and from the Camera End Unit. Two single-mode optical fibers carry WDM-multiplexed signals between the units. All video, audio, and data inputs and outputs use standard connectors. Multiple LEDs provide video, audio, and system status information. The Control Room Unit is available in a portable or rack-ready version. The portable version can be powered by a 10 to 18 Vdc source or via battery using the Anton/Bauer mount. Consuming a maximum of 20 watts, battery operation in excess of six hours is easily achieved. The rack-ready version is optimized for use in permanent (fixed or mobile) installations. Using the optional Live-Link Sr. Rack Mounting Enclosure, one or two units can be mounted in three spaces (3U) of a standard equipment rack.

Selected Live-Link Sr. Control Room versions provide 2-wire party-line support instead of 4-wire. Alternately, applications that require a 2-wire party-line circuit to be interfaced with the Control Room Unit’s 4-wire interface can use the Studio Technologies’ Model 45A Interface.
