PCM 81
OPERATIONAL PROBLEMS
The PCM 81 will not lock onto an incoming digital signal.
Check the cables that you are using. DO NOT USE ANALOG AUDIO
CABLE TO CONNECT DIGITAL AUDIO.
Also check to make sure that your input signal complies with
S/PDIF format standards. The PCM 81 will recognize AES
professional format signals from an appropriate connector, but will
not necessarily read and transmit encoded information accurately.
