Operating the AD-2 as a clock master in D-D Mode may be desirable in a number of
situations, such as when processing the output of a digital audio workstation, or when
connected to an A-D converter with a poor-quality clock.
In either A-D or D-D mode, the question arises as to what output rates would be
assumed by Main or Aux output paths if they are set to ‘=DI’ but no external reference or
digital input is present (or if the Sync Mode is set to ‘Int’). In all such cases, the path’s
sampling rate defaults to 96kHz.
In all cases, care must be taken to ensure that the other digital audio equipment in the
system is either 'locked' to, or synchronous with, the AD-2.
