input basis.

As described in Chapter 2, there are four different types of ungated signal pro-

cessing paths that may be selected for each input. The different signal

processing paths for the four ungated signal types are summarized in the fol-

lowing table.

The default ungated type depends on the type of input signal as shown in the

following table.

Most applications benefit from the Line Input ungated signal processing path

for program audio and other non-microphone audio that is not usually

automixed.
An example of using the line input processing is shown in the following figure
