The PCM 80 can use its own internal clock as a timing reference, or it can reference an external clock source from the rear panel S/PDIF jack. Use ADJUST to select Ext (External), 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 80 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) or Cns (Consumer, also called S/PDIF).

Note: Although the PCM 80 will detect AES professional format signals, it is designed to be used with S/PDIF input. If your digital input is not S/PDIF, please be alert for locking problems and other potential errors, and be prepared to take the necessary steps to provide the correct for- mat input signal.
