If set the microphone preamp output is added to the ADC input signal.
If set the cell phone input is added to the ADC input signal.
If set the left stereo bus is added to the ADC input signal.
If set the right stereo bus is added to the ADC input signal.
Programs the closest expected sample rate of the mono ADC, which is a variable required by the
AGC algorithm whenever the AGC is in use. This does not set the sample rate of the mono ADC.
