INTRODUCTION
Thanks for purchasing this AP-411 Lip Sync Corrector from the AV Toolbox division of
tvONE. The AP-411 is a compact device used to correct audio/video timing mismatches that
result in the loss of synchronization of the two components of A/V program content. Since
this problem is virtually always caused by the program’s video component arriving after
the audio component, the AP-411 Lip Sync Corrector provides up to 300 milliseconds of
delay for the audio component to restore A/V synchronization to the program material. AV
Toolbox offers a wide range of video, audio and multimedia products.
