An example of using the line input processing is shown in the following figure where a program audio source
can be processed with parametric equalization, automatic gain control, dynamics processing, fader, delay,
and input mute.

The Sound Reinforcement path is selected by default for microphone audio because that processing path
includes the full echo and noise cancellation, but the path does not include the non-linear processing
associated with the acoustic echo canceller to avoid the application of any echo canceller suppression (or
ducking) to the signal. The application of using this path is shown in the following figure where a microphone
is connected and echo canceled and feedback reduced, but not automixed
