Chapter 1

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.

2.2 Equipment Required

A PC running Windows® 98 or later is required for proper installation of the DMA8:

Model DMA™8 Installation Manual Installation

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.
