Studio Technologies Live-Link Jr. 10X Series - Camera End Unit Optcon Duo

Product Code: ST-LLJR-CA-101

Key Features

Live-Link Jr. is a highly-integrated camera extender system optimised for electronic news gathering (ENG), uplink truck, and specialised broadcast applications. The portable camera end unit and rack-mounted truck end unit provide all the resources needed for a single-camera live event. Linked using just two single-mode optical fibres, the same excellent performance will be supplied whether the units are hundreds of feet or miles apart. Notable features of the Live-Link Jr. system include performance flexibility, support for high-quality on-air (program), talent cue (IFB) and intercom audio, and ease of use.

Studio Technologies Live-Link Jr 10X Series - Camera End Unit Optcon Duo

Video Transport

Live-Link Jr. transports one SDI video signal in each direction: camera-end-to-truck-end and truck-end-to-camera-end. 3G-, HD-, and SD-SDI signals are fully supported. A "loop" output is associated with each SDI input. This provides a signal that follows the embedding process within Live-Link Jr. This "post-embedder" signal can be valuable for "confidence" monitoring, transport of signals via coax, or as an aid during testing or troubleshooting. At the truck end the SDI signal originating at the camera end unit is provided as two independent, buffered SDI outputs.

Audio Transport

The camera end unit has two "mic/line" inputs that are compatible with microphone or line-level signals. Related features include adjustable input sensitivity, phantom power, and level metreing. Each input stage can be independently set for compatibility with line-level signals (0 dB gain) or mic signals (gain of 15, 30, or 45 dB). The provided phantom power is 48 Vdc to ensure correct operation with professional-grade microphones. Extensive filtering on the mic/line inputs minimizes the chance of audio performance issues occurring due to the presence of radio-frequency signals. Protection against damage due to ESD ("static") discharge is also incorporated.

Two balanced line-level outputs are provided on the truck end unit's back panel and are associated with the camera end unit's mic/line inputs. Two additional balanced line-level outputs are also located on the truck end unit's back panel. These outputs provide de-embedded analog signals associated with group 1, channels 1 and 2 of the transported SDI. These "convenience" outputs allow audio embedded, for example, by a camera connected to the camera end unit to be accessible without the need for an external de-embedder unit at the truck end. They can be very useful when connected to inputs on an audio mixer, speaker monitor panel, or RF transmission system.

Intercom

A major strength of Live-Link Jr. is its integrated 2-channel intercom system. With its extensive resources and capabilities the typical hassles and limitations associated with intercom system implementation should be a thing of the past. A 2-channel party-line intercom interface is provided on both the camera end and truck end units. This allows user beltpacks, such as the ubiquitous RTS® BP325, to be directly connected and powered. A fully functional camera-end-to-truck-end "comms" system can be up and running in just minutes. The advanced 2-wire-to-4-wire converter circuitry provides simply excellent audio performance. Adjustment of the converter's "nulling" is user activated by pushbutton switches on both the camera end and truck end units. The pushbuttons allow both the local and alternate-end nulling process to be started.

The Live-Link Jr. truck end also provides a 4-wire interface that is associated with intercom channel 2. An audio input and audio output allows direct interfacing with local and remotely-located matrix intercom systems. In this manner intercom users at the camera end unit, truck end unit, and remote locations can be part of the same intercom circuit.

The party-line interface on the camera end unit provides a power source and the required signal terminations. This allows direct connection of user beltpacks; a typical application could use up to three BP325 units. With its selectable operating mode the truck end party-line interface offers additional resources. Most applications will have the truck end configured for stand-alone operation where power and signal terminations are required. In this mode up to five BP325 beltpacks could be connected. Alternately, the truck end's power source and signal terminations can be disabled allowing interfacing with an existing party-line intercom system. This will allow the truck end's party-line interface to become just another "user" on an already installed system.
