program. The alarm will then be activated if the measured loudness
exceeds the Alarm Tolerance . For example, if Over or Both is
selected, and the Reference Level is exceeded by the Alarm
Tolerance , the Loudness Screen will appear as follows, with the
measured loudness backlighted in red:
• Alarm Tolerance: This setting adjusts how far above or below the
Reference Level will activate the Over or Under alarms. It also
affects the size of the green segment in the LU meter. When an EBU
standard is selected, this setting default to +/- 1 LU and when the
IEC standard is selected, it will default to +/- 2 LU. This control
will allow further adjustment according to actual needs. Turning
the Alarm Tolerance control will select one of six possible
settings:
• +/- 1 LU
• +/- 2 LU
• +/- 3 LU
• +/- 4 LU
• +/- 5 LU
• +/- 6 LU
• Loudness Window: Pressing this knob will select one of the three
possible settings:
• Momentary (0.4 seconds) (default): This setting will cause the
loudness measurement to respond quickly to sudden jumps
in audio loudness.
• Short Term (3 seconds)
• Custom (1 second to 120 minutes): If Custom is selected by
pressing the Loudness Window knob, then rotating the
knob will select the integration time of your choice.
