SoundStructure Product Family
2 - 23
For additional flexibility in audio applications, there are four different
versions of the recording/ungated signal that can be selected through the
four-input router shown in the previous processing figures. This selection of
which type of recording/ungated signal to choose is performed on an input by
input basis within the SoundStructure Studio software as described in Chapter
5.
These four ungated versions are described in more detail below:
1. bypass version
2. line input version
3. noise cancellation version
4. sound reinforcement version
Recording/Ungated - Bypass
The recording/ungated-bypass version has no input processing other than a
fader gain control, input delay, and input mute. This version bypasses the
automatic gain control and dynamics processing as shown in the following
figure. This version can be used when it is important to have minimal audio
processing on an input signal.
Recording/Ungated - Line Input
The recording - line input version includes equalization, automatic gain
control, and the dynamics processing as well as fader gain control, input delay,
and input mute as shown in the next figure. This processing path is typically
used by line input signals such as program audio, and hence the name line
input path.
