XD10 Cinema Media Player, Installation and Operating Guide Version 2.1

5.3.5. Dolby
®
CP200 Operation
When the XD10 switches to digital, the normal signal paths are interrupted, and DTS signals are
inserted just prior to the Dolby
®
EQ cards, in effect taking over the cinema processor.
CP200: Program the automation optical default format to either “04” A-TYPE
or “05” SR, whichever the film requires.
When the XD10 switches out of digital, the cinema processor is released and reverts to the format
previously selected.
Unless modified, these cinema processors do not have a subwoofer input. In this case, DTS inserts the
subwoofer signal post-fader; the fader or mute will not affect the subwoofer level.
Check diagrams for sub connection.
5.3.6. XD10P Operation
XD10 units with the digital option should connect to the digital input on the XD10P using a double
shielded digital out cable. In this configuration, XD10 Ext2 is the format used for the XD10. (See the
diagram for DTS XD10 P Digital on page B-3 of Appendix B, Cinema Processor Interface Wiring
Diagrams.)
XD10 units without the digital option should connect to the analog input on the XD10P using the
standard 25-pin cable. In this configuration, XD10P Ext1 is the format used for the XD10. (See the
diagram for DTS XD10 P Analog on page B-2 of Appendix B, Cinema Processor Interface Wiring
Diagrams.)
5.4. XD10 Calibration and Setup
This section describes procedures for XD10 audio level adjustment, timecode reader sync adjustment,
sound performance verification, and fail-safe operation verification.
5.4.1. Equipment Requirements
Complete checkout and adjustment of the XD10 requires (as a minimum) a multimeter, a SPL meter,
and the DTS Demo film (which is part of the DTS Technician’s Kit).
The “B-Chain” calibration must be completed prior to adjustment of the XD10.
5.4.2. Setting and Adjusting Audio Output Levels
Channel setup tests and tones are pre-recorded onto the XD10 hard drive.
The audio playback level of the XD10’s built-in 1 kHz test tone has been fixed at 300mV RMS. This
level should match the audio buss level on the cinema processor that the XD10 is connected to. Verify
the buss level by consulting the manufacturer of your cinema processor.
The pink noise tests that are built into the XD10 are used only to make A-B comparisons to an
alternate sound source, such as magnetic sound track or analog sound.
Be aware that some external pink noise generator cards used on some cinema processors—
such as CP65 and CP55, which do not have internal pink noise generators—may have a level
discrepancy of as much as 1.5 dB. For this reason the 1 kHz test tone is used for setting the
XD10 audio output levels.
