INPUT BOOST
The input path to the ADCs is via a boost stage, which can mix signals from the microphone PGAs
and the line inputs.
The boost stage can provide up to +29dB additional gain from the microphone PGA output to the
ADC input, providing a total maximum available analogue gain of +59dB from microphone to ADC.
The microphone PGA path to the boost mixer is muted using LINMUTE and RINMUTE as shown in
Table 4. Microphone PGA to boost gain settings are shown in Table 5.
