5.2.5. Two Projector (Change-over) Theaters
Use a timecode “Y” cable to connect two readers to one XD20. Be sure to place each reader at the same
location on each projector. This is to ensure the soundtrack plays in sync. The timecode offset values
(distance from D600 reader to the projector’s picture gate) must be the same for each projector.
5.3. Connection to Cinema Processors
The following instructions are generic procedures intended to supplement the processor installation
instructions for your specific manufacturer's system. Cinema processor interface wiring diagrams are
located in Appendix B of this manual. They show connections and sub-connections.
Refer to the Installation Checklist on page xiii near the beginning of this guide.
5.3.1. Dolby
®
CP45, CP55, CP65, CP500, CP650, UltraStereo JS Series,
Panastereo and SMART Operation
The XD20 will automatically send one pulse to the cinema processor, changing the format to DTS.
Whenever the XD20 drops out, a pulse will be sent to switch the cinema processor back to an analog
format (usually SR).
Set the automation/cues on the film so they will not override the format change once the DTS has started
to play, which can result in switching to an incorrect format. Be aware that after a film break, the cinema
processor may drop out of digital format. In this case, the blue Audio LED on the XD20 will begin to
blink and you may have to manually select the digital format (on the cinema processor) for DTS
playback.
•
CP500 : Must have the Cat. 685 (analog input card) installed. DTS is accessed through
Format 11.
•
SMART : Mod VI and VII uses DDE interface cable E709.
For other SMART cinema processors, contact SMART directly at (800) 45-SMART or
+1.770.449.6698.
5.3.2. Dolby
®
DA20 SR-D
®
System
The XD20 can be connected to the Dolby SR-D
®
system without affecting performance of the Dolby
system.
The DA20 connects to the appropriate XD20 breakout board. When the XD20 unit is off, the DA20
output is routed through the breakout board. When the XD20 system is on and playing in digital, the
DA20 connection (to the cinema processor) is switched out on the breakout card and the DTS digital
soundtrack is output to the cinema processor.
In most instances, the SR-D
®
system should be powered down when playing in DTS.
5.3.3. Sony SDDS
®
The XD20 system cannot connect to the DFP-D2000 and DFP-D2500. It can connect to the DFP-D3000
and DCP1000. See the interface and cable and interface drawings in Appendixes B and D.
5.3.4. Panastereo CSP1200 and SMART
There is an Automation Preset for Panastereo CSP1200 and SMART CP. For information, see section
7.5.1.2 Predefined Formats,
