PRODUCTION DATA.
In the event that a microphone becomes disconnected from the inputs, the microphone bias resistors pull INxP to MICBIAS and INxM to ground. The combination of INxP shorted to MICBIAS and INxM shorted to ground for the same channel in a diagnostic sweep results in an open input fault condition.
