Time code enables different pieces of studio gear to work together but it has become a source of problems and frustrations for many engineers. The SA-1 can eliminate these frustrations by identifying quickly and accurately time code errors and providing a comprehensive report.
• 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 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 is included which 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 SA-1 accurately monitors the phase between time code and video and reports even slow drifts.
• Printed Time Code Report:
A comprehensive report can be sent to an external printer or computer via the rear panel serial port. This report includes format, video phase and time code errors.
