Dolby Laboratories CP950 - Configuring the Equalization Parameters

Configuring the equalization parameters
This chapter describes three methods for configuring the Dolby CP950/CP950A equalization (EQ)
parameters. You can use any of these methods, depending on your requirements:
1. Equalize an auditorium with the Dolby CP950 real-time analyzer by using a default room
configuration, and then use the standard one-third octave equalization (EQ) (internal real-time
analyzer), which is similar to the Dolby CP750 EQ (or the Grossman eq, which allows you to zoom in
and make finer adjustments).
2. Configure an auditorium with crossovers or a mix of analog and digital outputs using Dolby Atmos
Designer (DAD), and then upload that room configuration to the Dolby CP950/CP950A, and use the
standard one-third octave EQ, which is similar to the Dolby CP750 EQ (or the Grossman eq, which
allows you to zoom in and make finer adjustments).
3. Create a room configuration using DAD and use Dolby AutoEQ, which is similar to the Dolby CP850
EQ, to equalize the room.
Note: To use internal crossovers or both analog and digital outputs at the same time,
you must use the DAD soware.
Before using any of these methods:
• Use the front panel user interface (UI) (FPUI) to change the default IP address to your cinema
networking standard and connect to the Dolby CP950/CP950A web client using Google Chrome
version 71.x or later (for best results).
• Check the Dolby CP950/CP950A soware version by clicking info at the upper le corner of the web
client. If the version is not up to date with the current Dolby CP950/CP950A soware on https://
customer.dolby.com, download and install the current version. This provides the best environment
for performing the installation.
If you want to use DAD for the installation, you must use DAD version 3.3.7 or higher.
Aer upgrading the CP950/CP950A to the latest version, you can download the current version of
DAD soware by clicking downloads in the Dolby CP950/CP950A navigation bar. You can also
download the current version of DAD soware, release notes, and manual at https://
customer.dolby.com. In addition, you can access the DAD manual from the DAD soware Help
menu.
