GUIDE TO INSTALLATION AND OPERATION
AMX-3981 | 49
Enable Loudness Monitoring turns all loudness monitoring functions ON or OFF
RESET resets the measurements, and places a segment marker in the log file (but only if User Event is selected in
the Segment Marker area).
• Note that you can also program a GPI to trigger a loudness reset - the control is located on the Metadata | GPI
tab (see section 5.3.2 on page 21).
RUNNING / PAUSE shows the current status of the loudness monitoring.
• Click the button to change the status.
• PAUSE stops the measurement until the button is clicked again, but keeps the last value for logging and
measurement.
Segment Marker
Select the checkboxes corresponding to the events for which you want a segment marker inserted in the loudness log
file:
• User Event – a manually-triggered RESET (but not a PAUSE).
• GPI – a RESET triggered externally via GPI input.
• Dialnorm change – a change in Dialnorm value in the incoming metadata stream.
• Coding Mode Change – a change in the coding mode, either through the manual settings or detected in the
incoming metadata stream.
Note that segment marker triggers in one PGM will generate segment markers in the logs for all PGMs.
