Preferences may be stored as Presets, thereby having suitable settings for different
conditions easily at hand.
Loudness Scale
Can be set to either “Loudness Units, LU” or “Loudness Full Scale, LUFS”.
Note how LUFS is the same as LKFS. For more info, see paragraph about LKFS, LUFS
and LU.
When “LU” is selected, the radar and numbers appear as shown in Fig 4 Left. Note
numbers in the outer ring and the Program Loudness descriptor are based on a
relative scale with Target Level as 0 LU.
When “LUFS” is selected, the radar and numbers appear as shown in Fig 4 Right.
Note how numbers in the outer ring and the Program Loudness descriptor are based
on an absolute scale.
0 LU Equals
Sets the loudness required to obtain a 12 o’clock reading on the outer ring, which
is the same as the border between green and yellow on the Radar page. 0 LU is the
reference to aim at.
Low Level Below
Determines where the shift between green and blue happens in the outer ring. It
indicates to the engineer that level is now at risk of being below the noise floor.
True Peak Indicator
Sets the level at which the Peak indicator lights up.
