Each digital home video delivery method, be it cable, satellite or DVD, can often introduce artifacts that create delays between picture and sound. This is often noticed as a speech / lip-sync error when the actors voice becomes audible before lip movement. This abnormality can be so pronounced that the affected DVD or broadcast is unviewable.

The Primare Delay Box, when inserted between the signal source and processor, has the ability to detect and correct sync as well as make delay corrections in very small increments. The Delay Box will restore perfect lip-syncing to virtually any digital audio output device.
