Input Audio Status
Displays signal status and payload for embedded and
discrete audio received by the card.
Individual signal status and peak level displays for embedded audio input pairs, and AES/analog input pairs as described below.
AES pair status also shows sample rate.
• 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
®
E encoded data.
• Dolby Digital: Indicates embedded channel or AES pair contains Dolby
®
Digital encoded data.
Note: • Dolby status displays occur only for valid Dolby
®
signals meeting SMPTE 337M standard.
• 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.
