Brainstorm SR-112 Plus SR-TCG SR-112 Distripalyzer with Time Code Generator
Used extensively in live applications, the SR line hasbecome a standard for show control.
The SR-112 reshapes and distributes timecode through its 12outputs, sending it over long lines with no signal degradation. It analyzes thesource for quick diagnostic and generates or repairs timecode, locked to videoif required.
The industry standard SR-112 is designed to distribute timecode through its 12 buffered outputs while analyzing it. The reshaper sendsclean time code, even over long cables, making it ideal for live environments.
The front panel includes a large 8 digit reader and an LCDdisplay showing the units status and reporting errors as they are detected. Allmodern SMPTE and EBU SD/HD rates are supported.
With the option TCG, the SR-112 can also generate new timecode or repair exisitng one.
Distributor / Reshaper
The SR-112 distributes and reshapes time code through a 1x12distributor.
Reshaping
The Brainstorm Time Code Distributors are more than audioDA’s: they reshape the signal before distributing it and by doing so, theSR-112 eliminates amplitude distortions and input level fluctuations.
Output Levels
Output levels are adjustable individually via the OutputLevel menus. Since the signal is reshaped, output levels remain constant,regardless of the input level.
Time Code Generator (TCG) Included Firmware
The included TCG module has 2 main functions: Repairing timecode and generating new time code.
Repairing Time Code
In REPAIR mode, the SR-112 fixes drop outs by regeneratingthe incoming code (jam-sync). It can also correct video phase when it is misaligned.
Generating new Time Code
In GENERATE mode, the SR-112 generates new time code. Starttime, format and frame rate can be set. The generator can be genlocked toexternal video.
Please Note: The SR-112-SR-TCG is the SR-112Distripalyzer with Time Code Generator Only.

Redundancy
two separate supplies can be connected to the 2 separatepower inputs. If one supply fails, the other takes over and an error isreported. The faulty supply can be swapped without having to power down.
