Digital Audio Lip-Sync Corrector
The definitive answer to lip sync error for up to four
sources! Do you sometimes get frustrated by the lip-
synch errors when viewing? It occurs because of a
delay introduced by the processing of the picture. The
audio doesnt go through the same processing hence
the audio appears ahead of the image. If you use an
AV amplifier for your sound then we have a solution -
the Felston DD740 digital audio delay module. It
allows easy adjustable audio delay allowing you to get
everything back in perfect sync. There are four inputs
and you can switch and adjust from your armchair
with the supplied remote.
