Getting Started
2.1 Dolby Digital Encoder and Decoder
The discrete 5.1-channel mix will encode and decode in a Dolby Digital 5.1-channel
system and remain discrete 5.1. When mixing and monitoring in 5.1, it is important to
have monitors set up and calibrated correctly so the mix will play properly when
decoded by the consumer.
Monitoring through an encoder and decoder is important in regards to downmixing
and Dynamic Range Control (DRC). Using a Dolby Digital encoder and decoder in a
monitor chain will allow quick examination of the variety of ways a consumer may
hear a mix. Dolby Digital offers many features to maintain backward compatibility as
well as to allow consumers the ability to customize their listening environments. For
best results, features such as downmixing, DRC, and bass management need to be
checked during content creation and delivery to see if they meet the intent of the
content provider as well as the needs of the consumer. Encoding with a Dolby
Laboratories Model DP569 Dolby Digital encoder and monitoring with a Model
DP562 Professional Reference Decoder provides monitoring capabilities for these
parameters in addition to being able to simulate almost any listening environment.
