Audio Input Controls
Controls the AES Audio Input features for the eight AES pairs,
and displays signal status for the AES pairs and the 16
embedded audio channels. Also provides global unity routing/
parameter control resets.
Note: Also refer to AES Audio Input Advanced Features (p.
1-19) in Chapter 1,“Introduction” for detailed
information regarding these functions.
• AES SRC Individual SRC Disable/Enable control for each AES pair (1 thru 8)
disables or enables Sample Rate Conversion (SRC) bypass as follows:
• Disabled: In this mode, AES SRC for the corresponding AES pair is
bypassed. SRC is set to Disabled (bypass turned on) by default.
This mode is preferred where the AES rate matches the input video
rate. This mode is necessary when embedding undecoded,
non-PCM AES audio such a Dolby
®
E or Dolby Digital™ audio
streams.
Note: • In this mode AES rate must match the input video rate or
audio dropouts will occur.
• AES audio must be nominally 48 kHz.
• SRC is automatically disabled when Dolby ® E is
received.
• Enabled: In this mode, AES SRC for the corresponding AES input
pair is enabled. This allows the 9035 to interface with
asynchronous AES sources (sources in which the AES timing does
not match the video reference timing). SRC can be used to
compensate for minor clock rate differences in the AES stream and
the input video stream.
• AES Passthrough Individual AES Passthrough On/Off control for each AES pair (1 thru 8)
disables or enables Passthrough as follows:
• Off: Disables AES passthrough for the selected AES input pair.
Passthrough is set to Off by default.
• On: Passthrough is turned on, with the corresponding AES output
pair to act as a bit-for-bit copy with zero delay of the corresponding
AES input pair.
Note: AES Passthrough set to On overrides the normal audio
routing and delay. Gain and polarity control is not available
when AES passthrough is enabled.
• AES Zero Delay Embedding Individual AES Zero-Delay Embedding On/Off control for each AES pair
(1 thru 8) disables or enables Zero-Delay Embedding as follows:
• Off: Disables Zero-Delay Embedding for the selected AES input
pair. Zero-delay embedding is set to Off by default.
• On: The selected pair directly embeds into its corresponding group
(AES Pair 1 embeds into embedded channels 1 and 2; AES pair 2
embeds into embedded channels 3 and 4, and so on) with the
normal frame sync audio delay being bypassed.
Note: Zero Delay Embedding overrides the standard audio
routing system. For example, if AES Pair 1 is selected,
then the controls to route into embedded channels 1 and 2
will not apply. Gain and polarity control is not available
when zero-delay embedding is enabled.
