pressed the following screen appears on the right hand LCD display.
2.10.2 MADI Source Select
The MADI Src button is used to select which MADI source is active and effectively toggles
between the Coaxial (BNC) or Optical input port. The active input signal will be ‘reclocked’ out of
both Coaxial and Optical output connections regardless of the chosen input format.

however it is strongly advised that all digital input connections to SAM1 3GM and SAM1 MADI are
referenced to the same timing system.
