meter will show less signal activity.
Since the level_pre meter position is before any processing has been applied to
the signal, even if the signal is muted within the SoundStructure device, the
level_pre input meter will show any signal activity on that input.
The level_post meter is after any processing as shown in the following figure.
In the example above, if the input signal is muted the level_post meter will not
show any signal activity.
The exact location of the meter in the signal processing path depends on the
type of signal that is viewed as described next.
Microphone level_post
Microphone channels post level will measure the signal level at the conferenc-
ing output of the input processing as shown in the following figure.
The fader on the bottom of the input channel can be used to adjust the gain of
the output of the input processing. The fader will change the level of all three
outputs going to the matrix. The meter activity will show the affect of any gain
