analog gain in 0.5 dB increments. There is also an option to enable 48 V phantom power on each input.
Finally, the analog input signal is digitized and ready for processing.

Continuing through the signal path as shown in the next figure, the input signal processing continues
through the automatic gain control (AGC), dynamics processing, an automixer, an audio fader, and finally
through the input delay.
Each analog input signal is processed to generate three different versions of the processed input signal that
can be used simultaneously in the matrix. The following are the three versions of processed input signal:
● Noise canceled
● Sound reinforcement
● Recording/ungated
The AGC, dynamics processor, and input fader are linked together on all three audio paths and apply the
same gain to the signal paths based on an analysis of the signal earlier in the signal path.
