As a replacement for the industry standard SR-15+, the SR-112 reshapes and distributes time code, while analyzing it. A large 8 digit reader is included on the front panel and an error report can be sent via the ethernet port. All modern SMPTE and EBU SD/HD rates are supported. But, unlike the SR-15+, the new SR-112, with the optional generator software (TCG), can also repair bad time codes and generate new ones.
TIME CODE ANALYZER
Eliminates frustrations and downtime by identifying quickly and accurately errors with a powerful time code analyzer:
• Time code format & Frame Rate:
The front panel displays separately the format (24, 25 or 30), the drop frame status and the frame rate of the incoming time code.
For example: 30 drop at a rate of 29.97. No more guessing!
In addition, the frame rate counter can show potential problems such as jitter or wow and flutter.
• Time code errors:
Time code errors such as repeated frames, drop outs etc. are detected and reported on the front panel along with the faulty addresses. A buzzer sounds whenever the analyzer detects an error.
• Video Phase:
In post production, it is essential that time code be synchronous with video (i.e. the video frame must be perfectly aligned with the corresponding time code word). The SR-112 accurately monitors the phase between time code and video and reports even slow drifts.
• Time code report:
A comprehensive report that includes format, video phase and time code errors can be sent to a computer via the rear panel Ethernet port.
DISTRIBUTOR/ RESHAPER
While analyzing, the SR-112 distributes and reshapes time code through a 1x12 distributor:
• Buffered outputs:
The 12 time code outputs are balanced and buffered, avoiding the problems caused by multing a single source.
• Output Levels:
Output levels are adjustable individually via the Output Level menus. Since the signal is reshaped, output levels remain constant, regardless of the input level.
• Reshaping:
The Brainstorm Time Code Distributors are more than audio DA’s: they reshape the signal before distributing it. By reshaping the signal, the SR-112 eliminates amplitude distortions and input level fluctuations.
TIME CODE GENERATOR - OPTIONAL SOFTWARE: TCG
An optional software (TCG) can be purchased that adds a time generator module to the SR-112. This TGC has 2 main functions: Repairing time code and generating new time code.
• Repairing Time Code:
In REPAIR mode, the SR-112 fixes drop outs by regenerating the incoming code (jam-sync). It can also correct video phase when it is missaligned.
• Generating new Time Code:
In GENERATE mode, the SR-112 generates new time code. Start time, format and frame rate can be set. The generator can also be genlocked to external video.

Time Code Reader:
The 8 digit LED Display indicates hours, minutes, seconds and frames.
The display also flashes error descriptions when detected.
LCD Display:
In addition to being used for SET UP, the 32 carachter LCD display indicates the following:
- Format and rate of the incoming time code
- Format and rate of the video reference
- User Bits
- Video Phase
- List of errors
Dual redundancy: two separate 12VDC supplies can be connected to the 2 separate power inputs. In the event one fails, the other takes over and an error is reported. Then, simply change the faulty supply.
Power supply requirement: 12VDC @ 18w min.
