UEX/650 Upgrade Kit

1 Introduction

The UEX/650 Upgrade Kit converts a Dolby® Model CP650D Digital Cinema
Processor into a CP650 with Dolby Digital Surround EXTM film soundtrack playback
capability. For a detailed description of the format, please see Section 7.

The kit also adds four S/PDIF digital signal inputs. These inputs accommodate PCM
audio at sample rates of 48 and 44.1 kHz, plus Dolby Digital (consumer) bitstreams.

The signal input/output 25-pin D-connector is located on the rear panel of the CP650,
labeled “Option Card I/O.”

Note: Your CP650 must be capable of decoding Dolby Digital film soundtracks to

play films with Dolby Digital Surround EX soundtracks. If your cinema
processor is a Model CP650SR, you must first install a Cat. No. 773 Dolby
Digital Decoder Board. The UD/650 Upgrade Kit is available for this purpose.

The UEX/650 kit consists of:

• A Cat. No. 790 Dolby Digital Surround EX Decoder/Digital Input Board

• Mounting hardware and connector

Check CP650 Software Version

Perform this step before you install the Cat. No. 790 board. The CP650 operating
system software must be version 2.1 or higher. With the CP650 operating normally,
follow these steps:

Press the left menu button multiple times to step
through the menus to About this CP650.

Note: You can also press and hold the left

menu button while rotating the front­panel fader knob clockwise to step
through the menu items.

About this CP650 has three menu screens.

The first screen displays the version number of the
installed operating system software. If the version
reads “2.0.x.x”(x = any number) or earlier, you
must update the operating system software to
version 2.1.x.x or higher.

Press the illuminated format button to return to the
top menu screen.

2 Handling PC Boards

This upgrade involves handling printed circuit boards. Many components are very
sensitive to static electricity and can be destroyed if static charge on your body
discharges through the component. You do not even have to touch the component to
damage it. Before touching the components on the PC boards, ground yourself by
rubbing the frame of the unit with each hand or wearing an earthing strap.

3 Installation Steps

1. Remove mains power from the CP650 by unplugging the rear-panel power cord.

2. Open the setup control panel access door.
