The new Live-Link Jr Remote Camera Interface System from US-manufacturer Studio Technologies is a compact interface system for single-camera capture of events, concerts, corporate meetings, ENG and uplink vehicle applications. Carrying on from the company’s original Live-Link system, Live-Link Jr. transports one SDI video signal in each direction: camera end-to-truck end and truck end-to-camera end, supporting SD-, HD- and 3G-SDI data signals. All audio and support signals are transported between the two units as embedded SDI data. Performance can be maintained over distances due to two single-mode optical fibers which link the system. The camera end unit allows for remote powering using hybrid fiber/copper cable, 12 volt DC or Anton/Bauer or “V-Mount” batteries. The truck/studio end unit also offers both AC and DC powering capabilities, with failsafe operation from the DC input, should the AC mains fail. Two mic/line inputs, which are compatible with microphone or line-level signals, are offered from the camera end unit. Related features include adjustable input sensitivity, phantom power and level metering. 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). 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. Furthermore two additional balanced line-level outputs are also located on the truck end unit’s back panel to provide de-embedded analog signals associated with group 1, channels 1 and 2 of the transported SDI signal. 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/studio end. A 2-channel party-line intercom interface is provided on both the camera end and truck end units, allowing beltpacks to be directly connected and powered.. Additionally, a “4-wire” input and output allows direct interconnection with matrix intercom systems. Two line-level audio signals can also be transported from the truck end to the camera end via fiber connection, allowing for IFB communications. The balanced line/IFB inputs are located on the back panel of the truck end unit and allow the connection of a variety of analog audio signals, including talent cueing.
