Introduction
Thank you for purchasing the Dolby®Model DMA™8 Digital Media Adapter™. This
new cinema audio tool, a direct result of Dolby’s mission to develop technologies that
improve sound recording and reproduction, allows you to stay at the forefront of
quality entertainment presentation now and into the future.
The DMA8 expands the use of a cinema beyond traditional film applications. It
equips any theatre for a wide variety of uses, providing capabilities far beyond that of
simply showing movies to the general public. The DMA8 enables theatres to provide
audio solutions to today’s alternative programming challenges, such as pay-per-view
events and digital broadcasting.
The unit provides a straightforward interface with existing Dolby cinema processors
CP650, CP500, CP65, CP55, CP45, and CP200. High-quality audio can be presented
from a wide variety of the audio sources:
•High-definition video server
•PCM
•DVD
•Dolby Digital (consumer, non-film-based)
•Broadcast
•Dolby E
The DMA8 is compatible with existing theatre automation. Its accommodation for
multiple formats and future upgrades make it an essential tool for an evolving digital
cinema market.
When the DMA8 is in Film mode, standard six-channel analog signals from any
source, such as a DA20, are routed through the DMA8 to the six-channel input of a
cinema sound processor. In Digital Media mode, the DMA8 decodes and routes
signals from a variety of non-film sources (PCM, DVD, broadcast, Dolby E, and with
an optional Cat. No. 767 card, SDI) to the existing cinema sound processor. The
DMA8 software enables the user to select programs for applications that contain
multiple audio formats.
Like all Dolby cinema sound products, the DMA8 is fully supported by hundreds of
factory-trained technicians worldwide, on-call emergency assistance, and the most
experienced distributor network in the industry.

2.3 Mounting—Proper Grounding
Various types of noise may be present in and around the projection booth without
audible signs of anything being wrong. Proper mounting and wiring of booth
equipment helps ensure trouble-free performance.
We recommend that star washers be installed on all rack-mounting screws to ensure
good ground contact. This helps prevent electrical noise problems.
Figure 2-1 Use Star Washers
The DMA8 must be mounted in the same rack as the cinema processor to avoid
potential problems with ground loops, radiated interference, and so on.
WARNING: Follow all local codes and regulations covering electrical wiring.
2.4 Fuse Information
WARNING: To reduce the risk of fire, replace fuses only with the same type
and rating.
The DMA8 uses a universal switching power supply that handles the full range of
nominal mains voltages between 100 and 240 VAC, and any frequency between
50 and 60 Hz.
Check Main Fuse
The main fuse rating is:
T 1A L (time-lag, 1 amp, 250 V, 20 mm, low breaking capacity) for all operating
voltages.

2.5 Digital Audio Sources
The DMA8 accepts a wide range of digital audio sources including:
• High-definition video server, player, or receiver
• Professional digital video tape recorder (VTR)
• Digital satellite or cable television receiver
• DVD player
• Terrestrial digital television broadcast
• CD player
A range of digital audio formats are also accepted by the DMA8 including:
• Dolby®Digital (consumer, non-film-based)
• Dolby E
• PCM (digital stereo audio)
All of these sources and formats use one of the following three methods to package
the digital data into a physical connection.
Professional Interface Standards for Digital Audio
There are two professional interface formats used for digital audio: AES/EBU and
AES3. These formats stream the same digital data and professional audio header
information over copper conductor links, but use different types of conductors and
connectors.
AES/EBU uses a balanced connection (two conductors plus shield) with a
characteristic input impedance of 110Ω, nominal peak-to-peak signal level of 5 V,
and most commonly, XLR connectors. AES3 uses an unbalanced connection (one
signal conductor plus shield) with a characteristic input impedance of 75Ω, peak-to-
peak signal level of 1 V, and BNC (“push and twist”) connectors.
Professional digital audio equipment usually uses the AES/EBU format because
balanced operation yields superior noise immunity, as it does with analog audio
signals, and because XLR connectors have been standard on analog professional
audio equipment.
Professional video equipment usually uses the AES3 variation of this interface, with
BNC connectors. Like the use of XLR connectors on pro audio equipment, the
adoption of BNC connectors for the audio on professional video equipment stems
from their existing use for the video signal. Also, the unbalanced AES3 signal can
connect to more than one piece of equipment with the loop-through connectors that
are available on some devices. Lastly, it is robust for long cable runs.

Model DMA™8 Installation Manual Installation
2-5
Consumer Interface Standards for Digital Audio
The consumer interface standard for digital audio is S/PDIF (IEC61937). S/PDIF is
found using either coaxial unbalanced connections (one signal conductor plus shield)
with a characteristic input impedance of 75Ωwith RCA (phono) connectors, or a
fiber-optic cable with Toslink®connectors. The unbalanced coaxial connection has a
peak-to-peak signal level of 0.5 V. Although S/PDIF-specific cables with suitable
connectors can be purchased, good results can also be obtained using high-quality
75Ωvideo cable with the appropriate connectors and/or adapters.
Cable Issues
Even in digital audio, noise-free signals are still very important. The cable used for
digital signals is specifically designed for digital audio use even though it appears to
be the same as that used for analog audio or video signals. Any professional audio
equipment or broadcast supply company can provide 110Ωcable with connectors (or
without, if you wish to terminate them yourself) for AES/EBU connections and high-
quality 75Ωvideo cables with BNC connectors for AES3 connections. Use of cables
or connectors with incorrect impedance or those not designed for digital transmission
compromises the integrity of the bitstream and may create an unreliable link between
pieces of equipment, particularly with long cable runs.
Multiple Sources—Conversion Between Interface Standards
Although some details of the bitstreams used in the AES and S/PDIF standards differ,
the audio information is exactly the same. As a consequence, most audio equipment
accepts either standard with no need to convert the bitstream itself; this is the case
with the DMA8. However, if you intend to connect sources across different types of
digital audio inputs, do not attempt to convert a digital interface type by, for example,
directly wiring an XLR connector to a BNC or RCA plug. This causes an impedance
mismatch and signal reflections, resulting in degradation of the digital waveform. It
may seem to work, but the results are unreliable and dropouts occur.
For conversion between the AES3 and S/PDIF formats you can use high-quality RCA
(phono plug)-to-BNC adapters, since the cable and impedance are the same (75Ω).
For conversion between the AES/EBU and AES3 or AES/EBU and S/PDIF formats,
a simple and economical method is to use inline transformers. These devices perform
the necessary impedance and balanced/unbalanced conversion. The following table
shows some examples of suitable adapters. The unbalanced connector in these
examples is a BNC. BNC-to-RCA adapters can be added to connect to consumer
S/PDIF connections. The units listed use passive circuitry.

Higher-priced units incorporating active circuitry are also available. These offer
additional features like multiple inputs, inputs for Toslink digital connections, and
multiple outputs.
2.6 Connections
Refer to the connection diagrams in Section 2.7 for installation wiring to your cinema
processor. The diagrams are located at the end of this chapter. Use the appropriate
page for your cinema processor model. Pinout information on each connector is listed
in Section 5.4
To provide proper operation in locations where there is a large RF or other
interference field, ensure that the cable types, lengths, and pin assignments are strictly
adhered to. Shields must connect only to the chassis and should not be paralleled with
the “–” side of inputs or outputs.
Figure 2-3 Rear-Panel View
2.6.1 Digital Media Automation Connector
The DMA8 provides a ground-switching interface for connecting to a theatre
automation system. The automation system can switch between film sound (pass-
through) and a digital media source. The connector can be wired to automation
systems to switch the DMA8 in and out of Digital Media mode. This function is a
duplication of the front-panel Digital Media and Film buttons.

Model DMA™8 Installation Manual Installation
2-7
2.6.2 RS-232 Serial Control Port
The rear-panel RS-232 connector can be used for serial control of the DMA8 using
ASCII character strings for remote switching and testing. See Section 5.3 for a listing
of the available serial commands. An expanded command set will become available
in future software releases.
2.6.3 Serial Data In/Out—Auto Dolby Digital Surround EX Control
The Serial Data In connector accepts the film sound data bitstream from a
Dolby DA20. The Serial Data To SA10 connector outputs the bitstream to a
Dolby SA10 equipped with an Cat. No. 814A Surround EX™auto-switching board.
Note: SA10s equipped with the original Cat. No. 814 (non-A) board do not need
wiring to this connector. Automatic switching of Surround EX does not
function.
If you have an SA10 equipped with a Cat. No. 814A board, disconnect the existing
serial data cable from the DA20 rear panel and connect it to the DMA8’s Serial Data
To SA10 connector. Add a jumper cable to connect the DA20 Serial Data output to
the DMA8’s Serial Data In connector.
When in Film mode, the film sound data bitstream passes directly from the DA20 to
the SA10, allowing the DA20 to control the Surround EX switching function in the
SA10.
When in Digital Media mode, the DMA8 controls the automatic Surround EX
function of the SA10 by inserting (or not inserting) the Surround EX data flags in the
bitstream to the SA10.

Notes:
1. Follow all local electrical and building codes.
2. Use earthed (grounded) conduit wherever
possible. Avoid routing signal wiring near electric
motors, rectifiers, power wiring, dimmer wiring or
other sources of electrical noise.
3. For two conductor with shield wiring, use
Belden 8451 2-conductor shielded cable or
equivalent: tinned copper, twisted pair, 22 AWG
stranded tinned copper drain wire, aluminum-
polyester shield, 100 percent shield coverage,
conductor to conductor (111pF per meter).
4. All shields must be connected to the CHASSIS
of the CP500 or DMA8 rather than to circuit
(audio) ground. This achieves the RF interference
immunity .
For D-connectors, a metal housing must be used
and the shields must be connected to the housing.

Notes:
1. Follow all local electrical and building codes.
2. Use earthed (grounded) conduit wherever
possible. Avoid routing signal wiring near electric
motors, rectifiers, power wiring, dimmer wiring or
other sources of electrical noise.
3. For two conductor with shield wiring, use
Belden 8451 2-conductor shielded cable or
equivalent: tinned copper, twisted pair, 22 AWG
stranded tinned copper drain wire, aluminum-
polyester shield, 100 percent shield coverage,
conductor to conductor (111pF per meter).
4. All shields must be connected to the CHASSIS
of the DA20 or DMA8 rather than to circuit (audio)
ground. This achieves the RF interference
immunity .
For D-connectors, a metal housing must be used
and the shields must be connected to the housing.
required by European EMC standards
5. Re-attach existing cables (Dolby part No’s
83134 and 83135) to the DMA8 as shown.
(Cables are included in CDA/65 cable set).
6. Shielded cables (Dolby Part No. 83442) are
included in the CDMA/A cable set.
