4.1 Connecting audio from a cinema server with a 25-pin D-
connector output
You can configure the audio from a digital cinema server with a 25-pin D-connector audio output to connect
with the Dolby Accessibility Solution Server.
Procedure
1. Connect the 25-pin D-connector to RJ-45 adapter to the digital cinema server AES output.
Note: The 25-pin D-connector to RJ-45 adapter comes unpinned. The 25-pin D-connector female
to 25-pin D-connector female adapter (gender changer) is necessary when configuring a Dolby
DSP100, DSS200, or DCP2000 to use the 25-pin D-connector to RJ-45 audio adapter. You may need
to consult the cinema server documentation AES audio pinout information to pin this adapter.
2. Connect the AES channel 1-8 end of the audio Y-cable to the 25-pin D-connector to RJ-45 adapter AES
channels 1-8 (side A) port, and then connect the RCA cable end to the CH 7-8 input on the Dolby
Accessibility Solution Server.
3. Connect the AES channel 9-16 end of the second audio Y-cable to the 25-pin D-connector to RJ-45 adapter
AES channels 9-16 (side B) port, and then connect the RCA cable end to the CH 15-16 input on the Dolby
Accessibility Solution Server.
Typically, the accessibility tracks are on channels 7, 8, 15 and 16. The audio Y-cables are designed to pass
channel 7 and 8 for Hearing Impaired and Visually Impaired tracks, and channel 15 for Sign Language
Video to the Dolby Accessibility Solution Server. If you are using any audio mapping in the digital cinema
server to remove audio signals from channels 7, 8, 15 or 16, then the audio Y-cables will not function in
your scenario. We recommend that you leave channels 7, 8, 15 and 16 unchanged. Alternatively, you
could build an audio Y-cable that matches your setup needs.
4. Connect the AES channel 1-6 output end of the audio Y-cable to the AES channels 1-8 input on the cinema
audio processor.
The audio Y-cable routes channels 1-6 to the cinema audio processor and routes channels 7 and 8 to the
Dolby Accessibility Solution Server.
In case the AES channels 1-6 end of the audio Y-cable cannot reach the audio processor, a coupler is
provided to extend the audio Y-cable.
Note:
If the cinema audio processor AES input is a 25-pin D-connector as opposed to RJ-45, then you
need to use a 25-pin D-connector to RJ-45 adapter. The 25-pin D-connector to RJ-45 adapter
comes unpinned. You may need to consult the cinema audio processor documentation AES audio
input information to pin this adapter.
