• How DTS Effects other Cinema Processors
Dolby CP200 Operation
The automation should set the CP200 processor’s optical default to either “04” A-type
or “05” SR . When the DTS switches to digital, the normal signal paths of the CP200
are interrupted. The DTS-6 signals will be inserted just prior to the CAT64 EQ cards,
in effect taking over the CP200. When the DTS-6 switches out of digital, the CP200 is
released to function as normal and default to the format previously selected.
Unless modified, the CP200 does not have a subwoofer input. DTS normally inserts its
subwoofer signal after the CP200. As a result, the subwoofer level will not be effected
by the fader or mute.
Dolby CP55, CP65, CP500, and UltraStereo JS Operation
The DTS-6 will automatically pulse the audio processor to the digital format when it
starts to play a digital sound track. Whenever the DTS-6 drops out of digital, a pulse
will be sent to switch the audio processor back to the optical format. On units equipped
with a DTS D490, D496, or D497 logic board, the pulse to switch back to optical will
be blocked if the audio processor is not in the digital format. Example, if the
automation switches to non-sync, the DTS-6 will not switch back to optical. The DTS
D490, D496, and D497 logic boards also have a jumper which is used to select between
A-type or SR as the fall-back format.
The DTS-6 will only pulse the audio processor into the digital format when it first
switches to digital. After the show has started (or the show is re-started after a film
break) make sure the automation doesn’t switch the theater processor back out of the
digital format. Set the automation/cues so no audio format change takes place after the
DTS has switched into digital. Switching to nonsync at the end of the show is OK.
Dolby CP500
*
Must have the Cat. 685 (analog input card) installed.
*
JM21 on the DTS-6 50-pin cable uses the DTS D561 (interface cable) to connect to the “6 CH.
INPUT”
on the CP500. Format 11 is normally used to access this connector.
*
The DTS D715 (logic card) interfaces DTS BS22 (on 50-pin cable) and connects to the
“AUTOMATION” connector on the CP500. Logic for Format 11 is already programmed in on stock
units from Dolby.
Dolby DA10 / 20 SR-D
TM
System
The DTS-6 can be connected to the Dolby SR-D
TM
system without effecting its
performance. The DA20 connects to the DTS-6 JM11 connector through a special
adapter, *D462. When the DTS-6 is off, the DA20 output is routed through the DTS-6
from JM11 to JM21. When DTS is on and playing in digital, the DA10 / 20 connection
(to the cinema processor) is broken inside the DTS-6 (via relays) and the DTS digital
sound track comes out of JM21. SR-D should be powered down when playing DTS.
* Use the DTS D462-00 adapter with the Dolby CP200
* Use the DTS D462-01 adapter with the Dolby CP65
Sony SDDS
TM
The DTS system does not effect nor connects to the SDDS
TM
system.
