without losing a sample in the outgoing audio signal.

ICC switches the clock source between word clock, MADI optical, MADI coaxial, and
internal, seamlessly, when the MADI optical, coaxial or word clock inputs fail and the other
port is locked - or to internal. ICC will not fall back to an AVB sync source and also will not
affect a chosen AVB master clock.
