• Loudness Mode: Pressing this button alternately turns program
loudness mode on or off. You can define a measurement associated
with the ITU1770/1771 recommendations. The loudness level is
measured in LKFS.
• Channel Select: Pressing this button and then rotating the Balance
knob control moves the red box from channel to channel. Pushing
the control has no effect. The channels scroll left and right as
necessary.
• Loudness Contribution: Pressing this button and then rotating the
Balance knob moves the yellow dot among the radio buttons to
select this channel's contribution to the loudness measurement
within the contribution fields to allow you to select how the channel
contributes to the loudness measurement. When the Loudness
Mode
is Off mode, this control doesn’t function.
In Program Loudness Mode, there is no difference between the
contribution of a front channel or a center channel. However, the
software will allow you so select, at most, one channel to be
designated as a center channel. The software will allow a loudness
measurement to be defined with no center channel contribution.
