Meter Types
There are typically two types for meters that are available for each input chan-
nel - a level that is before, or pre, any processing known as a level_pre and a
level that is after, or post, any input processing known as level_post.
The level_pre meter always shows the signal level just after the A/D con-
verter. This meter shows the effect of the analog signal gain before any digital
processing takes place as shown in the following figure. Chapter 8 discusses
how the analog gain should be set for best performance. The level_pre for all
input signals is shown in the following figure.
Within SoundStructure Studio, the level_pre signal meter is adjacent to the
analog input gain slider in SoundStructure Studio, as shown in the following
figure. Adjustments to the gain slider will be reflected in the meter - add more
gain and the meter will show more signal activity. Lower the gain and the
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.
