Acuma Labs RTA-31 User Manual page 10

In the INPUT column of the Plugin Configuration screen, select an
input source for the RTA-31. This can be an auxiliary send, a Pre-
or Post-DSP channel insert, or the main left or right mix. In this
example, we've chosen the Pre-DSP insert point for Channel 1.
If you wish to deactivate
the plug-in from a UFX
card slot, select none
from the PLUGIN
column's pull-down menu.
