Left Descriptor parameter
Parameter settings:
Off
Program Loudness (I)
Sliding Loudness
Loudness Range (LRA)
Max Momentary (M)
Max Short Term (S)
Max True Peak (TP)
Peak/Loudness Ratio (PLR)
Use this parameter to define what Descriptor
should be shown in the lower left corner of the
Radar page and the Stats page. See “Descrip-
tors” on page 18.
Selecting Max Momentary (M) or Max Short
Term (S) will automatically set the Max Loudness
Time parameter to 0.4 sec or 3 sec.
Right Descriptor parameter
Parameter settings:
Off
Program Loudness (I)
Sliding Loudness Sliding L.
Loudness Range (LRA)
Max True Peak (TP)
Peak/Loudness Ratio (PLR)
Use this parameter to define what Descriptor
should be shown in the lower right corner of the
Radar page and the Stats page. See “Descrip-
tors” on page 18.
Target Loudness parameter
Parameter range: -6 to -36 LUFS (or LKFS, de-
pending on name setting) in 0.5 steps
The Target Loudness parameter specifies the
loudness level to generally aim at. It affects a
number of functions and displays in LM2n /
LM6n, and must be set according to the stan-
dard you need to comply with.
Current broadcast standards require Target
Loudness to be in the range between -26 and
-20 LUFS. For instance, EBU R128 calls for -23
LUFS while ATSC A/85 specifies -24 LUFS.
The Target Loudness parameter affects these
functions and displays:
It sets the reference point for loudness
measurements in LU. If the Loudness Unit
parameter is set to LU, Program Loudness,
Sliding Loudness and Loudness Max will be
shown in LU relative to LU Reference. Conse-
quently, measurements that a on precisely on
target will consequently read “0.0 LU”.
It defines the “12 o’clock” value of the Ra-
dar meter.
Radar Speed parameter
Parameter settings: 1, 4, 12, 30 min,1, 2, 4, 12,
24 hours
Radar Speed controls how long each radar rev-
olution takes. Select from 1 minute to 24 hours.
You may “zoom” between the settings without
loosing data as long as the history isn’t reset.
The radar remembers up to 24 hours. Clicking
