Introduction
1.1 About the Dolby CP650 Cinema Processor
The Dolby CP650 is a self-contained, all-digital cinema processor capable of
supporting Dolby Digital, Dolby Digital Surround EX, Dolby SR, Dolby A-type, and
Academy mono film sound playback.
The CP650 provides inputs for two projector soundheads (both analog and digital), an
external six-channel processor, two nonsync sources, and a PA microphone. Its audio
outputs are balanced, with a multipin connector configured to the THX standard. The
CP650 is the first cinema processor to incorporate an Ethernet connection, enabling
theatre personnel to monitor the unit’s functions remotely from a PC.
For decoding analog soundtracks, the CP650’s state-of-the art design incorporates the
only digital implementations of Dolby A-type and Dolby SR decoding to meet Dolby
Laboratories’ own rigorous standards. Reductions in the cost of powerful DSP
circuitry have made it possible for the first time to replace the analog circuitry
previously necessary for the accurate reproduction of A-type and SR soundtracks.
An easy-to-read LCD screen, plus simple front-panel format selection and control
buttons make it easy to install, operate, and maintain the CP650. Installation is further
simplified by built-in test instrumentation that includes a real-time analyzer. Third-
octave equalization, plus bass and treble trim controls, are provided for up to seven
channels (Left, Center, Right, Left Surround, Right Surround, Back Surround Left,
and Back Surround Right). A digital parametric equalizer is provided for subwoofer
equalization.
Easily-programmed internal software manages most existing or likely future formats.
While an external PC is not required for setup, a full-featured software package is
available in a variety of languages to facilitate the setup process. A serial connector
for a PC, an input for a calibration microphone multiplexer, and a variety of test
points are all accessible behind an access door on the front panel. Built-in diagnostic
software runs automatically whenever the CP650 is turned on.
Calibration settings for a given theatre can be stored on a PC, and, if necessary,
transferred directly to another CP650, or other modules, minimizing the need for
additional calibration after repairs. As improvements to the CP650 digital control and
processing software are developed, the latest revisions will be downloadable from a
PC to the CP650. Updates to the digital processing used for Dolby Digital
soundtracks are included from time to time on Dolby Digital release prints, and
download automatically into the CP650 the first time such a print is played in the
cinema.

1.6 About Dolby Digital Surround EX
Dolby Digital Surround EX adds a third surround channel to digital film sound, a
concept first envisioned by sound designers at Lucasfilm’s Skywalker Sound post-
production facility. Jointly developed by Dolby Laboratories and Lucasfilm THX,
Dolby Digital Surround EX gives sound mixers a new level of creative freedom.
Dolby Digital Surround EX is fully compatible with all current 5.1 digital sound
formats and theatre systems. Prints that use it play normally with current systems, and
provide the extra surround channel when played using a CP650 cinema processor
equipped with the Cat. No. 794 board, or earlier Dolby cinema processors equipped
with the Dolby model SA10 adapter.
It has long been known that a center screen channel is necessary to ensure the precise
localization of front sounds for all viewers, including those seated to the sides of the
theatre. Dolby Digital Surround EX brings similar benefits to the surround
soundfield. With Surround EX, a back surround channel is reproduced by the speaker
array at the back of the theatre, while left and right surround is reproduced by the side
arrays. This means that sounds can now be positioned behind the audience, opening
the door to exciting new effects, such as true 360° pans.
The back surround channel also makes front-to-back and back-to-front transitions
more realistic. Flyovers really seem to pass overhead, rather than down the sides of
the theatre. Even ambient sound reproduction is improved, being less affected by the
width of the theatre. Equally important, the new back surround channel assures that
even viewers seated close to the left or right of the theatre experience the total
surround ambience intended by the filmmaker.
The UEX/650 kit upgrades the CP650D 5.1-channel digital cinema sound processor
to three surround channels that can play digital prints prepared with the Dolby Digital
Surround EX process. The installation requires wiring the surround speakers into left,
back (split into two groups), and right. Two power amplifier channels are required
for powering the two groups of back surround channel speakers. The figures on the
next page show the surround signal distribution for conventional 5.1-channel
surround and for Dolby Digital Surround EX format.
Auto Surround EX
On Dolby Digital soundtracks that contain a data bit signifying Surround EX
encoding, the CP650 will automatically switch to Dolby Digital Surround EX
decoding (operating software version 1.2 and above).

1.8 How to Identify Types of Soundtracks
Edge of film Dolby Digital soundtrack Analog soundtrack Picture area
Figure 1–2 Photograph of Film Soundtracks
A Dolby Digital, Dolby Digital Surround EX, stereo optical (Dolby A-type or SR), or
mono optical print should be identified as such on both the film can and the leader.
However, with handling, the identification may be lost. If neither is available, close
inspection of the film itself will help distinguish the various types. Digital data blocks
are printed between the perforations on the side of the film next to the analog (Dolby
SR) track.

Chapter 2
Installation
Do not connect the CP650 to mains power until all connections have been made.
If air-conditioning noise is audible in the theatre, arrange for lubrication of the motor,
fan bearings, adjustment of belts and drives, and cleaning of filters to reduce the
ambient noise to a minimum. If the air-conditioning cannot be repaired switch it off
while the CP650 is being aligned.
2.1 Replacing an Existing Sound System
If the CP650 replaces an existing cinema sound system, play a typical film before you
remove the old system so you will have a benchmark for comparison to the new
system.
2.1.1 Before playing the film:
•Verify that the existing power amplifiers are in good working order.
•Verify that the existing speakers are in good working order, and that there is no
loose or missing hardware, structural parts, or damaged drivers in the enclosures.
•Verify that all wiring is present and properly connected and that crossovers are
operating and are correctly adjusted.
•Check the polarity of the speaker connections.
•Verify that there are adequate ground (earth) connections.
•Verify that radio interference problems are adequately resolved.
2.1.2 While playing the film:
While you run the film, listen carefully in various parts of the theatre for audio system
problems, including:
•Hum,
•Noise, clicks, pops,
•Distorted sound,
•Poor tonal balance (lack of high-frequency or bass content),
These problems must be resolved before you can proceed with the new installation.

2.1.3 Disconnect the old system
• Disconnect power from the existing cinema sound equipment.
• Disconnect all cabling from the existing sound processor. Leave the cables
connected to the power amplifiers, booth monitor, etc.
2.2 Check Fuse and Bypass Mains Voltage Selector
WARNING: Check that the correct main fuse has been installed. To reduce
the risk of fire, replace only with fuses of the same type and rating.
The CP650 uses a universal switching power supply that can accommodate nominal
mains voltages from 100 to 120, and 200 to 240 VAC, at frequencies from 50 to
60 Hz.
Check Main Fuse
The main power supply fuse is a 6.3 Amp, 250V, 20 mm, time-lag, low breaking
capacity fuse (T 6.3 L). With a small flat-blade screwdriver, open the fuse
compartment door on the AC power input housing (see figure 2-1).
Figure 2–1 Main Fuse Assembly
Remove the fuse carrier and check that the fuse in the active (left position) is of the
correct rating. The fuse carrier must be inserted into the compartment with the fuse
oriented to the left. Do not force the carrier into the compartment. Damage will
result. The polarizing clip must be attached on the right side of the carrier at the rear.
Snap the fuse compartment door closed.
Check Bypass Supply Mains Voltage Setting
The bypass power supply mains voltage selector switch is accessible through a hole
in the top cover of the CP650. Use a screwdriver to set the switch to either 120 or
220 VAC. Figure 2-8 shows the switch location.
Caution: Be sure to check this setting. If the bypass voltage selector is set to 120 V and the
unit is connected to 220 V mains voltage, the bypass power supply fuse will blow.
