Playing Dolby Surround 7.1 Audio
Preparation of a Dolby ® CP750 Digital Cinema Processor for Dolby Surround 7.1 audio
requires four steps:
1. Upgrade the cinema processor and server software, if necessary.
2. Make any necessary changes to the AES audio cable connecting the server and
processor.
3. Manually change the audio output of the DSP100 Dolby Show Player (if your
auditorium uses one).
4. If necessary, make changes to surround speaker wiring to accommodate Dolby
Surround 7.1 audio.
This chapter provides details of the setup processes for auditoriums using Dolby cinema
servers. If your auditorium does not contain a Dolby cinema server, contact the server
manufacturer to ensure you have 16 ‐ channel playback capability and to obtain the
necessary digital audio pinouts of the server. Sixteen ‐ channel playback is required because
the Back Surround Left (Bsl) and Back Surround Right (Bsr) audio channels are carried on
channels 11 and 12 (AES pair 6).
5.1 Required Software
The Dolby Digital Cinema server requires, at a minimum, software release v.4.2.1.
The CP750 requires software version 1.2.6.5 or later.
Install all required software updates before proceeding.
5.2 Cable Connections
Each combination of server and sound processor has its own cabling requirements. Refer
to the section that matches your equipment. The combinations are:
• Connecting a DSP100 to a CP750
• Connecting a DSS200 to a CP750
