Recognized as a valuable problem solver in many post production studios throughout the world, the SR-15+ provides three essential functions in one compact unit.


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 audio 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-15+ accurately monitors the phase between time code and video and reports even slow drifts.

    • Printed time code report:
A comprehensive report that includes format, video phase and time code errors can be sent to an external printer or computer via the rear panel parallel and serial ports.


While analyzing, the SR-15+ distributes and reshapes time code through a 1x5 distributor:

    • Buffered outputs:
The 5 time code outputs are balanced and buffered, avoiding the problems caused by multing a single source.

    • Output Levels:
Output levels are adjustable individually via front panel pots. Since the signal is reshaped, output levels always remain constant.

    • 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-15+ eliminates amplitude distortions and input level fluctuations.


    • Source Select:
The Stripper can extract a synchronous Pilot Tone from time code, video or power line AC.

    • Selectable Waveform:
The Pilot Tone can be a sine wave or a square wave.
