EXTERNAL CABLE ASSEMBLIES
•
••
• 6-Track Cable Assembly - D434
The 6-track cable is broken into three parts: JM11, JM21, BS22. The white dot on
plugs indicate pin 1.
- JM11 is used as an input from other sound sources (such as the CP200 pass through)
to the DTS-6. This includes other digital sound sources such as Dolby SR-D
TM
.
- JM21 is used as an output from the DTS-6. When the DTS-6 is playing in digital,
only the DTS-6 output appears at JM21. If the DTS-6 is powered off or if it is not
playing in digital, then any signal fed into JM11 appears at JM21, and if no signal is
fed into JM11, then no output will be seen at JM21.
- BS22 is used to control some logic circuits on cinema processors.
•
••
• Stereo Cable Assembly - D436
The stereo cable is currently being used for only subwoofer output to some cinema
processors. A relay built into the DTS-6 will pass the analog subwoofer or play the
DTS subwoofer.
•
••
• Timecode Cable Assembly - D435
This cable connects the DTS Timecode Reader Head to the DTS-6 Processor. On
single projector (platter) systems, this cable has a single connector at both ends. For
dual (change-over) projector systems, this cable has a single connector at one end and
two connectors at the other end. See D477 for assembly diagram.
EXTERNAL BREAK-OUT BOARDS
•
••
• Generic Logic Break-out Board - D431 - Connects to BS22 on D434 if a “special
logic” board is not used.
•
••
• Special Logic Break-out Boards
These boards are used to block the pulse that selects the optical format when the
processor is in nonsync. You may select the default format to SR or A-type. These
boards are used with the following cinema processors:
- D490 is used with the Dolby CP55
- D496 is used with the Dolby CP65
- D715 is used with the Dolby CP500
- D497 is used with UltraStereo
•
••
• Audio Break-out Boards
- D437-00 is our generic audio breakout board. Wires must be soldered to the board for
connections to the cinema processor. Has no spade lugs. Generally used for testing
the audio output from the DTS-6.
- D437-01 is used with the Dolby CP55 and CP65. Has spade lugs which are intended
to slide under the terminal strip of the cinema processor.
- D458-00 is used with the Dolby CP50. See D459 wiring diagram for connection.
- D458-01 is used with the Dolby CP100. See D460 wiring diagram for connection.
- DTS10B is used to attach the DTS-6 to UltraStereo processors.
