What do all the numbers mean?
All measurements are taken and presented with reference to the light pulse, so if the audio is ahead of
the light the readings are positive. Should the audio be behind the video then the readings are negative.
Readings are given in milliseconds ( ms ), and frames ( F ) if a frame rate has been entered.
For example, in a home cinema environment, if the synchronisation error were detected as +100ms
then introducing that delay within the AV Receiver/Pre-Amplifier would bring things back into sync.
The results vary a lot, what’s going on?
This is, surprisingly, normal. With all the digital processing that goes on in modern equipment it is rare
to get a set of readings that all exactly match one another. That is why Sync-One2 calculates various
statistics to help with the analysis, details on these are given later within the guide.
What is all this Calibration business?
Whenever Sync-One2 goes into Measurement mode it will calibrate itself. It is measuring the current
ambient levels of light and background noise, and then automatically adjusting to be able to filter these
out for more accurate readings and fewer false readings.
Ideally, always have Sync-One2 in the measuring position (i.e. pointed at the light/sound sources) when
turning on, or going back to the Measurement mode, to obtain optimal results.
During calibration flags indicating if an external audio source is in use, or a reminder that a Mask Length
(the minimum time between measurements, see Mask Length command) above the standard
has been set.
External audio source is being used for measurements
A Mask Time other than the default has been set
