  • Identifies time code, reports errors (rate, type, drop outs)
  • Monitors time code / video phase
  • Outputs a complete report via Ethernet
  • Eliminates level fluctuations
  • Buffered outputs; balanced or unbalanced
  • Adjustable Output Levels
  • Repairs errors such as drop outs or video phase
  • Generates new Time Code with or without video reference
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.


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.


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.


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
Connectors: Time Code in: XLR Female (x 1)
Video Ref: BNC (x 1)
Time Code outputs:
    - DB25 (1x) - Tascam/Avid analog pin configuration: outputs 1-8;
    - XLR Male (2x): outputs 9-10;
    - 1/4" jacks (2x) - TRS: outputs 11-12
Ethernet: RJ45 jack (x 1)
Power: 4 pin circular (x 2)
Power: 12VDC @ 5A
Redundancy: two separate supplies can be connected to the 2 separate power inputs. If one supply fails, the other takes over and an error is reported. The faulty supply can be swapped without having to power down.
