The PCM 81 can use its own internal clock as a timing reference, or it can
reference an external clock source from the rear panel S/PDIF or AES jacks.
Use ADJUST to select Ext XLR (AES), Ext Coax (S/PDIF), Int: 48kHz or Int:
44.1kHz. When either Internal rate is selected, the digital input is disabled. To
process audio from the digital input, you must select Ext.
When External clock is selected, and the PCM 81 detects valid digital audio, the
rate of the External word clock will be displayed with a label indicating the digital
audio format type: Prf (Professional [AES]) or Cns (Consumer [S/PDIF]).
