7.5.2. Fallback Format for Soundtrack
The Soundtrack Fallback menu is used to choose the “fallback” format selected by the XD20 when the
DTS soundtrack stops playing.
When the XD20 starts playing in DTS playback, it pulses the cinema processor to the DTS format. When
the XD20 stops playing in DTS playback—either due to loss of timecode, missing audio file, or another
unexpected error—it pulses the cinema processor to switch to an optical format. In many cases, it
switches to the SR optical format on the film, but this menu can be used to set it to different fallback
formats.
The pulse to the DTS format occurs when the Audio LED becomes illuminated, provided that the
conditions of the format automation mode are met (See Section 7.5.3). The pulse to the fallback format
occurs when the Audio LED goes off, and is dependent on the conditions of the Soundtrack Fallback
mode, shown below.
Note
: XD20 fallback format is always Nonsync (1) at the end of a feature film. The end of the
film is defined as the last two minutes of the last reel of film for the feature.

Fallback Format.
Automatic
The fallback format is selected by the header information in the DTS audio
file that is playing. Possible definitions are
SR
,
A
, or
MONO
. These
definitions are intended to reflect the optical format on the film. Almost all
DTS audio files will have SR
defined as the fallback format. XD20 pulses
the SR (1) pin for the SR signal – not SR (2).
None
There will be no fallback format pulse when the DTS audio stops.
Others
The fallback format will be the selected pin. Table 14, above, provides
options for a selected pin.
Note
: If the fallback format is set to SR (1) and that pin is not defined as one of the format
pins in the Pin Format menu, then XD20 will pulse the A format pin. If there is not an A
format pin, then it will pulse the MONO format pin.
7.5.3. Automation Operating Mode
This menu allows the operating mode of the format switching to be set to one of three ways. The default
setting is DTS-6D Emulation. The operating mode defines the conditions that need to be met for XD20 to
switch the CP to the DTS format. The operating mode applies only to format switching for film
soundtrack playback. It does not affect format switching for the video playlists soundtrack.
