The Dolby

Processor provides a configurable platform that provides the
unique ability to reconfigure analog I/O in the field, as well as allowing for future
upgrades through expansion cards. The base platform provides native-digital
processing with both AES/EBU and S/PDIF inputs and outputs. This chapter provides
an overview of each hardware configuration supported by the Processor.
2.2 Factory Configurations
Five Dolby Lake Processor configurations are available from the factory. These are
the most common configurations that will satisfy most system requirements. Each has
a unique code name to distinguish it.
2.2.1 Configuration Naming Conventions
At the beginning of the name is the acronym LP for Lake Processor . The letters and
numbers following LP define the input and output configuration. LPD stands for Lake
Processor Digital , where Digital represents both inputs and outputs. Since the
Processor has both AES/EBU and S/PDIF digital I/O native to the platform, the base
acronym is LPD. As an example, the code name LP4D8 represents the configuration:
Lake Processor, four analog inputs, digital I/O, and eight analog outputs. The letter
D
separates inputs from outputs. This code name is also used as the stock keeping unit
(SKU) for sales and support purposes.
