Working with LM2 presets
LM2 presets define parameters such as target
loudness, noise floor, and overload conditions.
You can use TC Icon’s Library functions to re-
name, store and recall presets – see “Recalling,
storing and deleting settings” on page 67.
LM2 – Radar Page
Fig. 49.: Fig 3.: The LM2 Radar page
Outer Ring: Current Loudness
The segmented outer ring of the Radar page
displays Momentary loudness. The “12 o’clock”
position represents the 0 LU point (i.e. Target
Loudness). Values above this point are shown
in yellow. The “LU Reference” parameter can be
found on the LM2 Main page.
The Low Level point is marked by the transition
from green to blue. The “Low Level Below” pa-
rameter can be found on the Setup page.
The user should be instructed to keep the out-
er ring in the green area, and around the “12
o’clock” position on the average. Excursions into
the blue or the yellow area should be balanced,
and not only go in one direction.
The numbers associated with the outer ring may
be referenced at either maximum loudness or
have a zero point set at Target Level. You can set
this on the LM2 Main page using the “Loudness
Unit” parameter. Either way of looking at loud-
ness is valid.
LUFS reading is in line with how peak level is typ-
ically measured in a digital system, and compat-
ible with Dolby AC3 and E metadata, while the
LU approach calls for a certain Target Loudness
to have been predetermined, like e.g. a VU meter.
