Installing a Dolby Digital Cinema System
3.3 Installing the Hardware in a Single Auditorium
This section shows you how to install the Dolby Digital Cinema hardware in a single
auditorium.
3.3.1 Unpacking the System
You should inspect the DSS220 and its shipping package and contact Dolby immediately if
you find any damage.
Identify a suitable location for the rack unit that will hold the DSS220. It should be situated
in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise,
and electromagnetic fields are generated. You will also need to place it near a grounded
power outlet. Read all of the precautions listed in Section 3.3.2.
3.3.2 Preparing for Setup
The DSS220 ships with a front-panel cover that you should install after installing the unit
in its rack, as described in Section 3.3.3.
Choosing a Setup Location
Leave approximately 30 inches of clearance in the back of the rack to allow for sufficient
airflow and ease in servicing.
Rack Precautions
Be sure to take these precautions when installing the rack:
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor
with the full weight of the rack resting on them.
• In a single-rack installation, attach stabilizers to the rack.
• In multiple-rack installations, couple the racks together.
• Before extending a component from the rack be sure the rack is stable.
• Extend only one component at a time: extending two or more simultaneously may
cause the rack to become unstable.
