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.
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 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.
DISTRIBUTOR/ RESHAPER
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.
STRIPPER
• 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.
