Calrec Artemis - Controlling Loudness Meters

CALREC Putting Sound in the Picture 147
Controlling Loudness Meters
Once Loudness meters have been set up
in the Main application, controls for each
Loudness meter can be accessed from
the surface.
In the Layers row of any panel, select
TOOLS, then METERS. The top section
of the top right hand button cell on the
functions row shows the LOUDNESS
option. Pressing this puts that panel into
Loudness Meters mode and populates the
Fader panel control cells with individual
controls to start, pause and reset each
individual loudness meter. See Fig 2.
The path width, path label and time since
last reset are also displayed.
As well as individual control cells for
each meter, there is a global control cell
within the fader row which starts, pauses
and resets all loudness meters together.
This global control cell is duplicated on the
Monitor/Spill panel.
