CP950A
The Dolby CP950 and CP950A are the next generation cinema processors from Dolby Laboratories,
which continues its leadership in the development of innovative cinema technologies. The Dolby
CP950 and CP950A feature modular designs that enable ease of maintenance and future upgrades. The
Dolby CP950 and CP950A support multichannel PCM, Dolby Digital, Dolby Digital Plus, Dolby E, and
Dolby TrueHD. The CP950 is designed for use in 5.1 or Dolby Surround 7.1 auditoriums or spaces. The
CP950A supports Dolby Atmos when the required enablement (license) is installed. Dolby Atmos vastly
expands the palette for content creators and enhances the audience experience in cinematic
presentations. You can upgrade a CP950 to a CP950A by purchasing part number CP950-UPG from
Dolby. This upgrade includes a CAT1710 Media Block and a CAT1741 Power Supply. In addition, to
perform this upgrade, you must purchase a Dolby Atmos enablement for the CAT1710.

1.1 About this documentation
This documentation shows you how to install and operate a Dolby CP950 and CP950A.
With the Dolby CP950 and CP950A, you can present high-quality audio from the following audio sources:
• Dolby Digital Cinema playback systems
• Onscreen advertising servers
• Digital video tape recorders (VTRs)
• Digital satellite or cable TV receivers
• Blu-ray Disc
• DVDs
• Compatible servers supplied by any party other than Dolby
The Dolby CP950 and CP950A provide the following audio input connectors:
• 8 × Audio Engineering Society (AES) 16-channel digital AES3 audio input
• HDMI input
• Stereo nonsync inputs (RCA)
• Microphone input (XLR)
• Two 1 × AES BNC input connectors
• CAT1710 media block board with Dolby Atmos Input Ethernet port (included only with CP950A).
The Dolby CP950 and CP950A provide the following audio output connectors:
• Dolby Atmos Connect output using either AES67 or BLU Link protocols
16-channel digital on the CP950
64-channel digital on the CP950A
• 16-channel analog audio outputs
The analog audio outputs are balanced TASCAM female DB25 connectors.

serial interface also supports ASCII commands.
You can configure the Dolby CP950/CP950A with macros that accept audio using the system inputs. An
independently adjustable global audio delay is assigned to each macro to ensure that sound and picture are
perfectly synchronized. You can assign unique delays to dierent macros using the same input. This provides
flexibility for alternative content sources, which oen require dierent delays.
The Dolby CP950 and CP950A utilize high-resolution multiple-rate equalization (EQ) for all channels. You can
perform the setup manually using the Dolby CP950/CP950A web client user interface (UI) through the
standard one-third octave EQ (internal real-time analyzer). Advanced users can run the automatic EQ process
in Dolby Atmos Designer (DAD) v3.3.x or later soware. You can download the current version of DAD
soware by clicking downloads in the Dolby CP950/CP950A web client. Authorized users can download the
current version of DAD soware, release notes, and manual at https://customer.dolby.com. You can also
access the DAD manual in the DAD soware Help menu.
You can back up Dolby CP950/CP950A settings to a PC and restore the backup to another Dolby CP950/
CP950A if you experience a hardware or soware failure. This minimizes the need for additional calibration
aer repairs or unit replacement.

1.2.3 Booth monitor speaker
With this front-panel speaker, you can monitor the audio on any active input or speaker channel. The speaker
channels are sampled prior to speaker crossovers or the LCR downmix (which mixes Le, Center, and Right
channels). The speaker channel is attenuated by 10 dB. Input sampling is not supported with macros that
support encoded audio.
The LCR downmix is the default option, which you can change in the FPUI or web UI .
1.2.4 Booth monitor speaker volume
With this smaller right-side volume knob, you can adjust the booth monitor speaker volume. The booth
monitor speaker volume defaults to the lowest setting (silent) each time you start up the system. The system
does not support automation or remote control of the booth monitor speaker fader.

1.3 Dolby CP950 and CP950A rear panels
The following figures show the Dolby CP950 and CP950A rear‑panel components.
Figure 10: CP950 and CP950A rear panels
1.3.1 CAT1700 input and output connectors
The Dolby CP950 and CP950A receive analog and digital audio through the input connectors. The system
processes audio and applies equalization. Audio output is available using the analog or digital connections
or a combination of analog and digital. The CP950/CP950A input and output connectors are all located on
the CAT1700 main board, except for the CP950A CAT1710 media block, which is a separate board that enables
the system to receive and play back Dolby Atmos Digital Cinema Package content.
The Dolby CP950 supports a maximum of 16 channels. The CP950A supports a maximum of 64 channels. You
can mix analog and digital outputs, but you cannot exceed the maximum number of channels.
• Analog audio output is transmitted via two DB25 connectors: channels 1–8 on one connector and
channels 9–16 on the other connector. Both connectors are female and follow the TASCAM pinout.
• Digital audio output is transmitted via the Dolby Atmos Connect ports. These RJ45 Ethernet connectors
support audio in either AES67 or BLU Link protocols. The system can use only one Dolby Atmos connect
protocol at a time. Mixing AES67 and BLU Link devices on the same network is not possible.
Warning: To avoid exposure to dangerous voltages and to avoid damage to the unit, do not connect
any RJ45 ports to telephone circuits.
Installing a Dolby CP950 is similar to a Dolby CP750 installation. You can choose between the following
default room configurations in the web client user interface.
• 5.1, all analog outputs
• 5.1, all digital outputs (AES67 or BLU Link)
• 7.1, all analog outputs
• 7.1, all digital outputs (AES67 or BLU Link)

When using these default room configurations, the system uses full-range audio to feed external amplifiers or
crossovers. If needed, you can use Dolby Atmos Designer soware, version 3.3.7 or later, to create more
advanced 5.1 or 7.1 room configurations. This includes the use of internal crossover filters and changing the
routing parameters to use both analog and digital outputs (which cannot exceed 16 channels on CP950).
Installing a CP950A is similar to a CP850 installation, where you use Dolby Atmos Designer soware to create
a room configuration with up to 64 channels.
Caution: You can use all digital channels, or all analog channels, or a mix of analog and digital
channels, but you cannot exceed 16 channels of output on a CP950 or 64 channels of output on a
CP950A. In addition, if you use crossovers, you cannot split the output of a speaker between analog
and digital. For example, if the le speaker is three way, all outputs must be of the same type.
Following is a description of the Dolby CP950/CP950A CAT1700 input/output (I/O) components, from le to
right.
Channels 1-8 analog out/Channels 9-16 analog out
These 25‐pin female Tascam output D‐connectors can provide up to 16 channels of balanced analog audio
output.
Hearing Impaired (HI) connector
You can use this RCA analog audio output for HI, or for any input selectable in the macro editor, although the
standard usage is for HI output. By default, the system routes AES channel 7 from a digital cinema playback
system to this output. Audio is heard only when activity is present on AES channel 7. You can configure
routing to this output using the web client macro editor. Changing the AES assignment for channel 7 to not
used changes the system so that it generates a mix of Le, Center, and Right channels, which is sent to the HI
connector. This is useful if you play content that does not have a dedicated HI track (trailers or advertising).
You can also enable audio delay changes for the 8× AES IN connector using the macro editor. This can help
you to accurately synchronize the HI audio with the auditorium sound when the HI audio is routed through
an external device with dierent audio-delay requirements. Similarly, in the macro editor you can use the HI
output as a more generic analog output by clicking the analog output selection tab, selecting the Analog
Output A / HI, configuration, and unchecking the Auto checkbox in the configure analog output screen. For
more information on this option, see Section 3.2.7.
Visually Impaired (VI) connector
You can use this RCA analog audio output for VI narration, or for any input selectable in the macro editor,
although the standard usage is for VI output. By default, the system routes AES channel 8 from a digital
cinema playback system to this output. Audio is heard only when activity is present on AES channel 8. You
can configure routing to this channel using the web client macro editor. You can also enable audio delay
changes for the 8× AES IN connector using the macro editor. This can help you to accurately synchronize the
visually impaired narration audio with the auditorium sound when the VI audio is routed through an external
device with dierent audio-delay requirements. Similarly, in the macro editor you can use the VI output as a
more generic analog output by clicking the analog output selection tab, selecting the Analog Output B / VI,
configuration, and unchecking the Auto checkbox in the configure analog output screen. For more
information on this option, see Section 3.2.7.
Microphone or real-time analyzer input
This MIC / RTA XLR connector allows you to connect and use a microphone with the Dolby CP950/CP950A for
public address announcements. You can also use this connector with a microphone for calibration when
using the internal Dolby CP950/CP950A real-time analyzer (RTA).
Note: When using the internal RTA, you must not use the microphone macro. Feedback could
damage the speakers.
