This uses two modes of Sync-One2, Measurement mode and Menu mode. Measurement mode takes
the readings and stores the most recent in a memory buffer. Always take a number of readings to
determine the error, to smooth out the variances in signal processing.
Once several readings have been taken, enter Menu mode and choose the Show Stats option.
This displays the average and span of the readings and gives the best indication of the situation in any
given system.
For example, if after a series of measurements, the Show Stats menu gives the following screen. The
low span indicates the system is stable but suffers from a video delay of about 32ms. If this were a
home cinema, adding an audio delay of 32ms and re-testing should result in a synchronised solution.
Should the span reading be high, say over 25ms this may suggest there could be inaccurate/anomalous
results within the memory buffer. Details of how to go through the memory buffer and remove any
suspect readings is given in the Show Stats menu item section of the guide.
If any adjustments have been made to the system under test, then always run the test again to confirm
the adjustments have brought things back into synchronisation. (Note, remember to clear the memory
buffer via the Clear All Stats menu item or the results could be confusing).
Depending on the various possible input paths, e.g. Blu-Ray players, network streamers, games
consoles etc. it might be required to configure a delay for each of the input devices if the audio
processor supports multiple values. If it is not possible to configure the individual input channels, pick
the most commonly used input, which is able to play suitable test file.
