If a Sync Source is chosen where a valid clock signal is not detected, then the Aurora will revert to Internal until a valid signal is present for the chosen Sync Source. To correct:
- Verify that the clock source is powered up.
- Verify that connecting cables are securely attached.
- Verify that the clock source has been set to operate off of its internal clock.
- Verify that the clock source is generating a sample rate that the Aurora can use (44.1, 48, 88.2, 96. 176.4 or 192 kHz)
