Dolby DP591 Audio Encoder
Quick Start Guide
20 August 2018
1 Overview
The DP591 introduces the immersive audio to existing live production creation, contribution, and
distribution infrastructures.
The Dolby DP591 delivers live audio that includes Dolby Atmos audio content, and also supports 5.1
and stereo audio formats.
The DP591 enables the audio engineer to:
•Encode PCM audio and metadata to the Dolby ED2 contribution format, Dolby Digital Plus, or
Dolby Digital Plus with Dolby Atmos content
•Transcode Dolby E to Dolby Digital Plus and Dolby ED2 to Dolby Digital Plus with Dolby Atmos
content
•Decode Dolby ED2 content to its original PCM channels
This documentation describes how to prepare the DP591 unit for its first usage.
See
Dolby DP591 Audio Encoder User's Guide
for detailed instructions. The guide is available on the
DP591 UI under the Help > User Manual section.
