Once a Dialogue Level value has been selected, either short‐term or infinite measurements
can be used depending on your preference. Again, see
Section 4.7.2 to understand the
differences between them.
5.2.3 Monitoring Downmixes
Once a Dialogue Level value has been set and a measurement mode selected, check
downmixes and make any adjustments necessary so that the mix translates best across the
appropriate listening environments.
A full dynamic range 5.1 mix may sound more pleasing than the same mix that is stereo or
Pro Logic downmixed. In some cases, a compromise on downmixes must be made to
ensure that the 5.1 mix remains the best.
Use the downmix parameters to help create the best downmix possible from your original
multichannel mix.

Check both compression modes on the full 5.1 mix as well as on downmixes. This is an
important step because you cannot be certain which mode consumers may be using. See
Section D.3 for detailed information on the DRC modes.
5.3 Using the DP570 with Other Dolby Equipment
The Cat. No. 549 GPI/O Controller provides a quick method to change downmix and
compression modes while monitoring. The DP570 can be used either with the DP569 Dolby
Digital or DP571 Dolby E Encoders by attaching the metadata connectors, and also with the
Dolby Media Encoder software application.
Note: Remember to prioritize your mixes.
