Chapter 1
Overview
This document will help users correctly install Dolby pro audio products into broadcast, postproduction, and other environments. (Operation of each unit is not covered in this document; for this information, refer to the dedicated user manual supplied with each unit. Additional copies of user manuals can be also obtained from Dolby Laboratories.) Upon purchasing a new Dolby product, please register it on www.dolby.com. Doing so will enable us to notify you of product upgrades and send other information of interest.
The units detailed in this document are the DP562, DP563, DP569, DP570, DP571, DP572, and DM100.
1.1 DP562
The DP562 is a multichannel reference decoder incorporating both Dolby Digital and Dolby Surround Pro Logic decoding. When producing material in Dolby Surround, the unit allows the effects of the encode/decode process to be monitored. When used for monitoring Dolby Digital encoding, it allows the effects of metadata to be auditioned, and the various downmixes to be heard.
1.2 DP563
The DP563 is a fully digital implementation of the Dolby Surround matrix encoder used in the analog SEU4 Dolby Surround Encoder. It has six digital inputs so that 5.1 material can be automatically downmixed to four channels before it is encoded. This unit is usually used in conjunction with a DP562 or DP570.
1.3 DP569
The DP569 Dolby Digital Encoder takes up to six input channels (for 5.1-channel operation) and outputs an encoded Dolby Digital bitstream. The DP569 can use metadata generated by another unit and can be controlled by a Windows PC using the supplied DolbyRemote software. A DP562 is used to monitor the encoded Dolby Digital bitstream.

Dolby Installation Guidelines Overview
1.4 DP570
The DP570 Multichannel Audio Tool allows users to generate metadata for input into either a Dolby E or Dolby Digital encoder, and to monitor the effects of metadata on an audio source in real time. It also includes features such as multiple speaker selection, audio channel routing (which eliminates the need for an external router), and separate inputs for Dolby Surround Pro Logic decoding and 5.1-channel monitor configuration.
1.5 DP571
The DP571 Dolby E Encoder encodes up to eight PCM audio channels plus Dolby Digital metadata into a single AES3 channel pair. Its one-frame PCM audio delay keeps linear PCM audio in sync with Dolby E encoded audio.
1.6 DP572
The DP572 Dolby E Decoder decodes up to eight channels of high-quality PCM audio plus Dolby Digital metadata from a single Dolby E-encoded AES3 pair, or from two audio tracks on a digital videotape, digital audio tape, or video server.
1.7 DM100
The DM100 Bitstream Analyzer is a very useful tool for installation engineers. It is a handheld, portable diagnostic tool that can monitor Dolby Digital, Dolby E, and PCM bitstreams. It can also generate test streams in any of the above formats. Structure of this Document
Chapter 2 of this document details the connectivity of each unit, including input and output formats, and signal levels of the status ports. Physical dimensions for each unit are also detailed in this section.
Chapter 3 covers typical installation issues, such as setup and calibration procedures for some of the units.
Chapter 4 discusses redundant operation between Dolby products, useful in broadcast and other applications.
Chapter 5 provides descriptions of common applications for Dolby pro audio products. This chapter also includes wiring details for these applications.
Chapter 6 discusses units that can be controlled remotely via serial port connection. It also covers details of the auxiliary data ports and metadata connections that can be required between the units.

Dimensions
The DP562 occupies one rack unit and measures 45 × 483 × 305 mm (1.75 × 19 × 12
inches). Its net weight is 4.5 kg (9.9 lb).
2.2 Audio Connections
The digital audio input is a 3-pin female XLR connector. The input will accept either PCM in AES/EBU format or Dolby Digital (AC-3) in IEC 1937 format (formerly IEC 958 Annex B) as specified in ATSC A/52 Annex B.
The digital audio outputs are 3-pin male XLR connectors. The outputs are PCM in AES/EBU format (5 Vp-p, 110Ω).
The analog audio outputs are balanced and use 3-pin male XLR connectors (0 dBFS = +24 dBu). The output impedance is 25Ω.
The headphone output is a ¼-inch standard audio headphone jack with +11.5 dBu maximum output into 600 nominal.
2.2.1 Serial I/O
The DP562 has a rear-panel RS-232 port. This port is used for software upgrades and can also be used to control most of the functions of the DP562. The unit must be in Remote Control mode before it will accept commands through the Serial I/O port. Remote Control mode is enabled in the User Menu, which is entered by holding down

Dolby Installation Guidelines Unit Connections and Dimensions
the User button for three seconds. The LED on the User button will illuminate when the user option is selected. This option is only available in version 2.5 or later of the unit software. See Section 6.4 for further information.
The DP562 communicates at 9.6 kbps and has a fixed unit address of 8282.
2.2.2 Status Activity and Remote Level Control
The Status/Remote connector on the rear panel allows remote monitoring of the status output activity and remote control of the analog output level. When the remote level control is enabled, the internal master level control is disabled.

The table above contains details of the pin connections for the Status/Remote port. The test box shown in the figure below can be used as an example for monitoring
Status/Remote port activity and controlling the analog output level remotely. A 10k
potentiometer is often used for the remote level control.
