D) Lipsync Delay
Using the Lipsync Delay
setting, you can modify the
timing of the audio signal, to
allow for the time delay of the
video signal caused by the
system. Because of the digital
calculations required for the
picture signal in the plasma or
LCD screen, the sound signal
can get ahead of the picture
signal. This can be seen, for
example, when the lip move-
ments are no longer synchro-
nous to the sound. Using the
Lipsync function, the sound can
also be delayed sufficiently, that
the picture and the sound get
back in sync.
This time delay can be set in a
range from 0 – 170 ms.
The Lipsync function appears
as the last menu field within the
Amplifier menu and affects all
sources that the M51 can play.
The Lipsync function is not
available in the Pure Analog
sound field.
You can adjust the time delay in
steps of 5 ms using the two
softkeys – Delay +. To do this,
you are advised to select a DVD
which features drums or other
percussion instruments. This is
the easiest way to be able to
synchronise picture and sound
with each other.
Lipsync in Multiroom system
In Multiroom operation, the M51
and the rooms in Zone 1 share
a common audio source, i.e.
both play the same source. This
is particularly advantageous in
open living areas, where the
rooms in Zone 1 adjoin the main
room with the M51.
If the M51 audio signal ex-
periences a delay through the
5.1 Decoder module, the M51
will transmit its sound later than
that in the rooms of Zone 1.
This time delay will be per-
ceived as an echo in the
adjoining rooms.
