If the timecode LED is blinking, and the XD20 is dropping out of digital after the items listed
above have been checked, call your theater technician for a system test. Ask the theater tech to
refer to TN-E698, which is posted on the free online Support site at
www.datasatdigital.com/support.
Note
: Later versions of the reader head do not require adjustment. These heads can be
identified by the “RoHS” sticker on them.
4.3.4.2. Timecode LED is Solid, but Audio LED is not Lit
If the XD20 timecode LED is on solid, but the blue Audio LED is not lit, then check the following:
1.
Verify that the soundtrack is loaded on the XD20 hard drive. From the Ready message on the
LCD screen, press

Features
to view the list of all
soundtracks loaded in the XD20 hard drive
2.
If it is not listed, find the disc and load it. The soundtrack must be loaded onto the hard drive
before you can play in the DTS digital format.
3.
Verify that the DTS soundtrack discs match the film by checking the feature title on the disc label
and the feature language.
4.3.4.3. Blue Audio LED is Flashing at Regular Intervals
If the Audio LED is flashing at regular intervals, then XD20 is reporting that it is not in the DTS format.
This would occur in the following situations:
•
The automation system may have selected a different audio format after XD20 had switched
to the DTS optical formats before switching to the DTS format.
•
If the automation mode is set to auto-switch, then XD20 expects that the automation system
first selects one of the optical formats—Mono, A, SR(1) or SR (2)—before switching to the
DTS format. If one of the optical formats is not selected, then XD20 does not pulse the DTS
format, and the DTS Playback
LED blinks.
•
If the automation mode is set to pre-select, then XD20 expects that the automation system
first selects the DTS format. If the DTS format is not selected first, then XD20 does not pulse
the DTS format, and the Audio LED blinks.
4.3.5. XD20 Switches Out of DTS Digital
1 If XD20 does not see timecode for four seconds, XD20 automatically switches the Cinema
Processor to the default analog (usually SR). Verify that the green LED on the D600 Timecode
Reader Head is glowing brightly and steadily while the film is running.
2 If the Timecode LED on XD20 or on the reader head is blinking, check the reader’s voltage,
using TN-E550. TN-E550 is posted on the online support site located at
www.datasatdigital.com/Support/
3 If the timecode light still does not illuminate steadily while film with timecode is running, use
TN-E698 to troubleshoot the problem. TN-E550 is posted on the online support site located at
www.datasatdigital.com/support.
4 Verify that all sound cues from automation are completed before timecode starts or after it ends.
If the sound format switches back to SR after the feature starts, then it is possible that automation
is switching the cinema processor and overriding the XD20 pulse to digital. To avoid this, add
some black leader before the start of timecode for the feature. It will give automation time to
pulse the cinema processor to SR. Then when DTS timecode is seen, XD20 will pulse the cinema
processor to digital, and it will stay there as long as valid timecode is seen by XD20.
