METERING
Loudness Meters
Loudness meters provide a way to monitor and regulate average loudness levels over the duration of a program.
Loudness meters are displayed as part of the meter they are assigned to on the External Meter Panel. There are
two loudness meters available on Brio 36.

Loudness Metering Modes
There are six loudness metering modes available on the console, the details of which are displayed in the table in Figure 5
on next page.
The loudness meter mode is set globally for the console: Tap METERS in the Show menu and tap the MODE button to
view a drop-down list of loudness modes to choose from. An appropriate loudness metering scale can also be set from
this screen, which alters the scale of all loudness meter bar graphs.
Loudness meter modes relate to standards set by organisations in different geographical regions. EBU (European
Broadcasting Union) relates to Europe, ATSC (Advanced Television Systems Committee) to North America and ARIB
(Association of Radio Industries and Businesses) to Japan. These are currently the main standards and are being widely
adopted in other geographical regions.
Two extra modes called DPP Live and DPP Non-Live have been added to provide additional guidelines in Live and Non-
Live production environments. This was set up by various broadcasters in a group known as the DPP (Digital Production
Partnership).

Controls for Loudness metering can be accessed from the Active Show>Meters>Loudness Meters page
