Input Audio Status

Individual signal status and peak level displays for embedded audio input pairs, and AES/analog input pairs as described below.
• Absent: Indicates embedded channel or AES pair does not contain recognized audio PCM data.
• Present - PCM: Indicates AES pair or embedded channel contains recognized audio PCM data.
• Dolby E: Indicates embedded channel or AES pair contains Dolby
• Dolby Digital: Indicates embedded channel or AES pair contains Dolby
Note: • Dolby status displays occur only for valid Dolby
• AES Dolby-encoded inputs that are routed directly to card are directed via a special path that automatically bypasses
SRC. However, AES inputs to other destinations (e.g., AES embedding) are first applied through SRC. These paths
disable SRC if Dolby-encoded data is detected. To avoid a possible "Dolby noise burst" if an input on these paths
changes from PCM to Dolby, it is recommended to set the AES SRC control for the pair to SCR Off for an AES input
that is expected to carry a Dolby signal.
