Menu Selection Descriptions

High Level Above : The High Level Above target alarm occurs when the integrated
loudness level is higher than the target value plus the range above the desired loudness
level for a period in excess of the duration setting.

Low Level Below : The Low Level Below target alarm occurs when the integrated
loudness level is lower than target value plus the range below the desired loudness level
for a period in excess of the duration setting.
These values are mode-dependent (ATSC A/85, EBU R 128, ARIB TR-B32, or Custom). When
you are in a specific mode you can only adjust the parameters associated with that
particular mode. When you change a loudness mode’s parameter, the High Level Above and
the Low Level Below target alarm parameters change also.
