MADI in

Receives PCM signals. This input is an unbalanced 75Ωfemale BNC connector per

AES-10-2008. It can also be a clock source.

AES out

Outputs PCM audio, Dolby ED2, or Dolby Digital Plus with Dolby Atmos content through

four unbalanced, 75Ωfemale BNC connectors. Signal levels per AES3-4-2009.

Video in

A 75Ωfemale BNC connector that supports video reference input, including a clock

reference (based on a voltage reference (Vref) signal).

SDI in

Receives PCM audio, Dolby ED2, and Dolby E in up to eight embedded SDI pairs. This port

also receives video and can act as a clock source.

SDI out

Outputs Dolby ED2, Dolby Digital Plus, Dolby Digital Plus with Dolby Atmos content, and

PCM in up to eight embedded SDI pairs. Outputs also video.

Command port (Gigabit Ethernet)

Connects a network to administer the unit through a PC web-based user interface (UI).

2.5 Inputs and outputs

The DP591 supports metadata input through the Ethernet connection, or PCM signal through

the input SDI or MADI port.

This table lists the available inputs and outputs, and their descriptions.

Input/output name Functional description

MADI input Receives up to 16 channels of PCM audio from an in-stream console for

encoding.

SDI input Receives HD-SDI and 3G-SDI Level A video with Dolby ED2, Dolby E, or PCM.

Command port Receives metadata over IP from a Dolby DP590.

AES output Transmits encoded Dolby ED2 and Dolby Digital Plus (with Dolby Atmos

content) bitstreams.

SDI output Transmits HD-SDI video, 3G-SDI Level A video, and Dolby ED2, or Dolby

Digital Plus with Dolby Atmos content bitstreams to a broadcast stream

component. When in decoding mode, transmits PCM decoded audio.

2.6 Clock source priority

Clock sources are prioritized in a pre-programmed order.

The clock reference source for DP591 is selected automatically, based on a pre-programmed

priority scheme and the availability of the particular sources. The priority is:

1. SDI

2. Vref

3. MADI

The highest available input becomes the clock source. For example, if SDI clock source is not

available, then DP591 attempts to sync with Vref, and so on.
