Chapter 4
Using the DP570 Features
This chapter covers each distinct feature of the DP570 in detail. The main power of the
Dolby
® DP570 is its ability to accept any program input and play it back over any
combination of speaker outputs using any combination of metadata parameters. This main
power is backed up by its ability to adjust virtually any of those variables on the fly.
As you listen, you can test your mix in different numbers and qualities of speaker in
different numbers of channels with different surround decoding strategies applied.
As you test, you can adjust metadata parameters to optimize the quality of the output. A
few of the most important metadata adjustments are discussed separately in later sections
of this chapter:
• Downmix monitoring
• Dialogue level
• Dynamic range control
4.1 Naming Programs
On the Dolby E tab you can assign a unique name to each program. You can use this feature
to make sure that the metadata stays properly identified throughout the production and
broadcast chain. Typically programs are named after their content; such as Game A or
Episode 5.
4.2 Adjusting the Monitor System
The monitoring system is fully configurable. You can modify any of its parameters at any
time, by clicking Setup, and viewing
the Monitor Setup Tab on page 62. Setting up your
monitoring system is discussed in full in Configuring a Monitor System on page 61.
4.3 Generating and Adjusting Metadata
You can choose to use internal metadata values generated by the DP570 or external values
supplied from one of the two metadata input connectors. You cannot use both external
sources in one program.
