Operational Problems
The PCM 90 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 90 will recognize AES professional format signals from an
appropriate connector, but will not necessarily read and transmit encoded
information accurately.
No Digital Audio Output
Check the Bypass state for any mute settings.
No Effects Output
Check the setting of Mix Mode at Control mode 1.1. Also verify that any
controllers patched to Input Level, or Mix are not turned off.
The PCM 90 performs a series of self tests each time it is powered on, then
displays the PCM 90 copyright notice. This should be followed by the display and
loading of the last loaded effect. If this sequence does not occur, contact Lexicon
Customer Service.
