13 Chapter 1 Introduction The Dolby CP750 Digital Cinema Processor is a direct result of Dolby Laboratories continued leadership in the development of innovative cinema technologies. The CP750 is a self contained, all digital cinema processor. It supports PCM and Dolby Digital audio, as well as Dolby Digital Surround EX TM, Dolby Pro Logic, and Dolby Pro Logic II playback. With the CP750, you can present high quality audio from the following audio sources and formats: Dolby Digital Cinema system Onscreen advertising servers Digital VTRs Digital satellite or cable TV receivers Blu ray Disc TM DVDs PCM Dolby Digital consumer bitstreams The CP750 provides analog audio inputs for: An external six or eight channel processor A nonsync source A public address microphone Its analog audio outputs are balanced, with a multipin connector configured to the THX standard. Built in Ethernet, USB, and serial interfaces accommodate PC control and cinema network connectivity. An independently adjustable global audio delay is assigned to each input to ensure that sound and picture are perfectly synchronized during digital cinema presentations. Different delays can be assigned to different inputs, providing flexibility for alternative content sources, which often require different delays. The CP750 is compatible with existing theatre automation systems and ASCII command strings. Its ability to handle multiple formats and future upgrades make it an essential tool for an evolving digital cinema market. Installation is simplified by built in test instrumentation that includes a real time analyzer and signal generators for pink noise, sweep tones, tones, and a phase check thumper. Third octave equalization, plus bass and treble trim controls, are provided for all channels. A digital parametric equalizer is provided for the Subwoofer channel. Easily programmed internal software manages audio settings and configuration. The full featured software package facilitates the setup process. Dolby CP750 Digital Cinema Processor Manual 1

14 Introduction Calibration settings for one unit can be stored on a PC, and, if desired, transferred directly to another CP750, minimizing the need for additional calibration after repairs. As improvements to the CP750 digital control and processing software are developed, the latest revisions are transferable from a PC to the CP750. Options available for the CP750 include the Cat. No. 868 Remote Fader and Cat. No. 994 External Power Supply. 1.1 About This Manual This manual covers both installation and use of the CP750. Following this introductory chapter are six chapters that give details of various topics: Chapter 2 Installation Chapter 3 Installing, Launching, and Connecting the Setup Software Chapter 4 Configuring the CP750 Software Chapter 5 Playing Dolby Surround 7.1 Audio Chapter 6 Aligning the Auditorium Chapter 7 Remote Control and Monitoring Chapter 8 Technical Reference Chapter 9 Replacement Parts 1.2 CP750 Front Panel The CP750 front panel shown in Figure 1 1 includes the following components from left to right: Front panel menu navigation buttons. Status display. Mute button. Main fader knob. USB port for firmware upgrades and setup software. Seven buttons that select an input source: Digital 1, Digital 2, Digital 3, Digital 4, Multi-Ch Analog, NonSync, and Mic. Four LEDs that indicate the presence of a Valid signal on each digital input. Digital 1 and Digital 4 have valid signals in Figure 1 1. Figure 1 1 CP750 Digital Cinema Processor Input Select Digital 1 Digital 2 Digital 3 Digital 4 Multi-Ch Analog NonSync Mic.

16 Introduction Figure 1 2 Left Center Right Processing Volume Input Subwoofer Left Surround Right Surround Figure 1-2 Front-Panel Display Mute Button Pressing the mute button shown in red in Figure 1 1 fades the audio output to all channels without disturbing the current main fader setting. Fade in and fade out speeds are separately adjustable from 0.2 to 5 seconds, using the PC setup software. The mute button flashes red when activated Main Fader Knob Use this knob to adjust the sound level. A fader reading of 7.0 is the nominal correct operating level. The main fader knob rotates continuously with no end stops. The knob is also used to adjust parameters during setup operations. When the fader knob is rotated between readings of 0 and 4.0, the output level changes in 20 db steps between 90 and 10 db. When the fader knob is rotated between readings 4.0 and 10, the output level changes in 3.33 db steps between 10 and 10 db. Figure 1 3 shows the characteristic graph. 4 Dolby CP750 Digital Cinema Processor Manual

19 CP750 Rear Panel H/I OUT: RCA jack for hearing impaired output. This is a center weighted sum of L C R. MIC. GAIN: For adjusting the gain of the microphone preamp. MIC. INPUT: 3 pin female XLR connector for a PA or auditorium equalization microphone. Phantom power can be applied using the setup software. MAIN AUDIO OUTPUT: 25 pin female D connector balanced audio output to the auditorium sound system. See Section for pinout details. MULTI-CHANNEL ANALOG INPUT: 25 pin female D connector carrying eight balanced analog channels. See Section for pinout details AC Input This is a simple unswitched IEC power inlet module Backup Power Port This is a four pin female XLR connector for use with the Cat. No. 994 External Power Supply Ethernet Port This is an illuminated RJ 45 10/100 Base T Ethernet port with activity LEDs, which provides an interface to a Dolby Digital Cinema network and also ASCII string commands over TCP to port You can also use this port for setup software and firmware upgrades RS-232 Serial Port You can use this port for serial control using ASCII string commands. The equipment connected to this port should have its serial port set to 9600 baud, no parity, 1 stop bit. Use a pin to pin serial cable. The same control functions are available through the Ethernet port Remote Connector This is not an Ethernet connection, but an Ethernet cable is used to connect to the Cat. No. 868 Remote Fader xAES IN Connector This 25 pin female D connector, linked to the Digital 1 button, receives four AES/EBU streams. The four AES input signals must be time aligned with each other. Typically, this input connects to a Dolby Digital cinema server. It accommodates PCM audio at 96, 48, and 44.1 khz, and 32 khz (16, 20, and 24 bits) and Dolby Digital at all data rates and sample rates. The decoding of Dolby Digital is restricted to the first AES3 channel pair. This connector has a floating ground. Dolby CP750 Digital Cinema Processor Manual 7

21 Questions or Feedback If the 5.1 output configuration is selected: For the top output (labeled 7), the source is channel 7 of the 4 AES input. No equalization or level control is applied. For the lower output (labeled 8), the source is channel 8 of the 4 AES input. No equalization or level control is applied. If the Dolby Surround 7.1 output configuration is selected: For the top output (labeled 7), the source is channel 1 of the Digital 2 input. No equalization or level control is applied. For the lower output (labeled 8), the source is channel 2 of the Digital 2 input. No equalization or level control is applied H/I Out Connector The hearing impaired output signal, on the female RCA connector labeled H/I Out, is unbalanced. It is a center weighted analog sum of the L, C, and R channels Mic. Gain This multi turn trimpot adjusts the gain of the mic preamp. If you use the microphone input for public address purposes, adjust this control for the desired volume in the auditorium. If you use it only for cinema alignment purposes, the trimpot will be adjusted using the setup software Mic. Input This input is for use with a balanced output microphone. Phantom power is provided, and can be turned on and off under software control using the setup software Main Audio Output Connector This connector is an 8 channel analog output (L, C, R, Ls, Rs, SW, Bsl, and Bsr), which is present on a male 25 pin D connector (300 mv reference level). Bsl and Bsr channels are required for Dolby Digital Surround EX installations. For other installations these channel can be configured to represent channel pair 7/8 of the 4xAES input. These mutually exclusive options are configured in the setup software Multi-Channel Analog Input Connector This connector is an 8 channel analog input (L, C, R, Ls, Rs, SW, Bsl, Bsr) designed to receive 300 mv RMS (ref) inputs from external sources and inputs on a female 25 pin D connector. These inputs are balanced and floating, but the common mode voltage must not exceed ±6 V peak. 1.4 Questions or Feedback If you have questions or comments about this document, please contact technical publications.
