channel set-
tings in the Preset Setup menu affect only the
source, or sources, to which the preset number
is assigned. The settings add or subtract up to
12dB from the channel level settings you made
in the “Speaker setup” – “Level setup” submenu page when you calibrated the system.
Note:
The factory default settings for these channels = 0 and Lipsync = Off.
Note:
When you select Exit at the bottom of this page you will return to the higher level menu
to proceed to the next setup page or review a previous setup page.
Lipsync
Lipsync
adjusts the audio to match the video
images. When the image you see on your screen
and the sound you hear from your speakers aren’t
synchronized the phenomenon is most noticeable
and annoying when actors are speaking. Correcting this problem is called Lip sync. An example
of video processing that can delay the video signal is the de-interlacing which trans-codes a 480i
(interlaced) signal to 480p (progressive scan). Video processing can occur in the DVD player, in an
external line scaler, or in the TV or video monitor. However, this processing comes at a price: it
delays the video signal so that you hear sounds a fraction of a second before you see its
matching image.
You may adjust
Lipsync
in precise 1 mS (millisecond) steps, up to 150 mS in a Preset for each
source that requires it.
Note:
The factory default setting = Off
THX Audio Setup
THX features
are called “post-processing”
because they are enhancements, not replace-
ments, for Dolby Digital and DTS modes. THX
provides further realism with most sources (see
the Mode Table on pages 33 – 35). With THX switched on, THX Surround EX is selected auto-
matically if a Dolby Digital soundtrack includes the digital “flag” that identifies it as carrying this
information for back speakers. You also need to select Back speakers in the
Speaker setup
menu,
Size setup
page,
>
Back speakers
(see pages 20-21).
