The Sync-Generator user manual and Sync-Generator Manager applications for Windows and Apple Macs are available from the buttons below.

To measure the audio-video sync in a system, you can attempt to do it visually from the pulses from Sync-Generator.  For accuracy without the guesswork, the recommendation is to use a Sync-One2 for system measurements.  This will show you the error in real-time.

Sync-Generator comes with a 2-year warranty.
