SoundStructure C-Series Signal Input Processing
C-Series Input Processing
Mic or Line A/D Parametric Acoustic Echo
Analog
Input Gain Converter Equalization Cancellation
Continuing through the signal path, as shown in the next figure, the input signal continues through the
automatic gain control (AGC), dynamics processing, an automixer, an audio fader, and finally through the
input delay.

Cancellation
Each analog input signal is processed to generate three different versions of the processed input signal that
can be used simultaneously in the matrix:
● Conferencing version
● Sound reinforcement version
● Recording/ungated version
