Generally speaking, the RV1106/RV1103 differential mode
via 1-MIC can meet the needs of most users. If the user
has other ADC mode usage requirements, you can configure
the corresponding ADC mode before starting the recording.
Please do not switch during recording as it will cause
pop noise due to the need to deinitialize the ADC.
Also, the RV1103 does not support full-differential
inputs for both ADCs.
