5.5.3.2. Check Automatic Fail-Safe (Default) Operation
This procedure will verify that, should the DTS timecode reader fail for any reason, the system will
automatically switch to optical sound format.
1. While the demo film is running, block the timecode at the reader or unplug the 9-pin connector at
the reader.
To block the timecode reader, insert a business card between the film and the lens of the DTS
Timecode Reader Head and keep it there for at least six seconds.
2. Verify that after 4 to 5 seconds of not seeing timecode, the DTS XD10 switches to the SR optical
sound format.
There should not be a dramatic sound level difference when the cinema processor switches from
digital to analog during dialog scenes. If there is a dramatic difference, check the cinema
processor’s levels first, then check the XD10 levels, and test again.
Remember, the XD10 output level must match the cinema processor’s buss level.
3. Now, restore timecode and XD10 should automatically switch the cinema processor to the DTS
digital format after about two seconds.
4. If a two-projector theater, repeat this procedure for Projector 2.
