Audio Input Controls
Controls the AES Audio Input features for the eight AES
input 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.
1-13) in Chapter 1,“Introduction” for detailed
information regarding these functions.
• AES SRC Individual SRC Disable 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 by default. This mode is
preferred where the AES rate matches the input video rate. This
mode is necessary when embedding non-PCM AES data 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.
Note: AES audio must be nominally 48 kHz.
• Enabled: In this mode, AES SRC for the corresponding AES input
pair is enabled. SRC enabled allows the 9085 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 normal audio
routing. Gain and polarity control is not available when
AES passthrough is enabled.
• AES audio must be synchronous with video to use this
feature.
• 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 audio sync 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.
• AES audio must be synchronous with video to use this
feature.
